Erosion Control | American Excelsior

Erosion Control Overview

Have you ever wondered why Curlex® is so popular?

If so, find out by viewing our Curlex Features and Benefits document.

Rolled Erosion Control Products (RECPs) are fibrous products, manufactured out of either natural materials (e.g. Curlex® aspen excelsior wood fibers, straw and coconut fiber), synthetic materials (e.g. polyester) or a mixture of natural and synthetic materials. Erosion Control Blankets (ECBs) are degradable RECPs and Turf Reinforcement Mats (TRMs) are RECPs that contain synthetic components. RECPs are used primarily to slow water runoff, provide effective sediment and erosion control, and enhance re-vegetation. These products are commonly applied to channel and ditch linings, slopes, culvert inlets and outfalls, riverbanks, and levees amongst many other applications.

RECPs are classified as short term, long term, or TRMs. Sediment Control Products assist when soil particles become entrained in runoff.

American Excelsior offers a wide variety of erosion control blankets under the Curlex® brand and other specialized products, like the QuickGRASS® Pro, to meet a plethora of needs.

Short-Term Erosion Control Blankets

The Original Curlex® Erosion Control Blanket

Designed using cuts of Great Lakes aspen fibers, these blankets were developed in the early 1960s to provide ideal conditions for grass seed growth, while simultaneously shielding the topsoil from water and wind erosion. These blankets also have a built-in swell factor, which allows the fibers to expand and form a stronger matrix when wet.

Curlex® CL Blankets

A cheaper, lighter version of the original Curlex Erosion Control Blanket®, this blanket promotes superior vegetation establishment support when compared to straight-lined fiber blankets (e.g. straw).

AEC Premier Straw® Blankets

Top quality agricultural straw fibers, which are certified weed seed free, are stitched in single or double netting to the top side or on both sides of the erosion control blanket.

Curlex® NetFree™ Blankets

A 100% biodegradable erosion control blanket made from sturdy, interlocking, curled and barbed Great Lakes aspen fibers which require no netting to support the structure, resulting in little to no incidences of tripping and animal trapping.

Long-Term Erosion Control Blankets

Curlex® Double Net (Curlex® II)

An organic, consistently thick, specific cut of Great Lakes Aspen curled wood excelsior with at 80% of six inches or greater fiber length.

Curlex® III

Made from Great Lakes Aspen excelsior fibers, these blankets encourage ideal growing conditions and provide seed and topsoil protection for up to 36 months.

AEC Premier Coconut™

Made from the finest quality strands of coconut fiber, this erosion control blanket is stitched together using a special UV-enhanced heavy black net on top and bottom.

AEC Premier Straw/Coconut™ Blankets

70% of the finest quality weed seed-free agricultural straw and 30% top quality strands of coconut fiber are intertwined and evenly distributed in the erosion control blanket and stitched with a UV-enhanced black net on top and a UV-enhanced green net on the bottom.

Turf Reinforcement Mats (TRMs)

Permanent turf reinforcement mats, for long-term protection against wind and water erosion, are a natural choice in place of stone or riprap in swales, ditch bottoms, and on long, steep slopes.

TriNet® Family of TRMs

TriNet® Family of TRMs: Three-netted heavy-duty TRMs for permanent protection in critical areas where vegetation alone requires extra protection from shear stress forces.

Curlex® Enforcer®

A bio-composite turf reinforcement mat designed for service of at least 36 months or more, this erosion control blanket is made from naturally seed-free Great Lakes Aspen excelsior fibers bound by 2 layers of extra heavy-duty black UV-enhanced netting to ensure permanent reinforcement between root systems and the established vegetation.

Recyclex® TRM and Recyclex® TRM-V

The first environmentally responsible turf reinforcement mat made from 100% recycled post-consumer goods designed to meet the most difficult erosion and sediment control challenges.

Sediment Control Devices

Curlex® Bloc

A naturally seed-free and nontoxic alternative to coir logs, these Blocs are high-density, natural filters designed to start degrading during the first year of its 3-year lifespan to allow seed and sediment into the Curlex fiber matrix.

AEC Premier Straw® Wattles

Made from certified weed-seed-free straw fibers, the dense nature of the finest quality agricultural straw fibers encased in durable netting allows water to pool instead of filtering through.

Curlex® Hi-Vis Excelsior Logs

Curlex Hi‐Vis Excelsior Logs are easy to move with their durable handles. But, the best part of them is what you don’t see. These are the only high‐visibility logs filled with the naturally seed‐free Great Lakes Aspen Curlex fibers that you know and trust.

Curlex® Sediment Log®

Designed to reduce the velocity of flowing water and filter out sediment, these environmentally-friendly, degradable sediment logs are made up of intricate, interlocked fiber log matrices.

Curlex® SiltTRAP™

A temporary buffer strip that offers a unique way of trapping and capturing sediment before it is washed away, filling gutters and clogging pipes. The naturally seed-free SiltTRAP™ fibers filter soil from the runoff and offer a mess-free alternative to silt fences.

Erosion Control Blanket (ECB) Netting

Each of the products containing the FibreNet trademark contain a 100% Biodegradable Jute netting. Single-netted products have a top net consisting of biodegradable jute and double-netted products have a top and bottom net made of biodegradable jute. Stitching that binds the fiber matrix to the FibreNet is also 100% biodegradable.

Curlex Fiber Matrix

The Curlex brand name signifies a quality product that is naturally seed-free Great Lakes Aspen curled excelsior fibers. Great Lakes Aspen is grown in the United States as a manageable, renewable forest crop.

The unique nature of the ECB fiber matrix is due to the engineered Curlex fiber. Curlex fiber matrices are composed of a specific cut of Aspen designed specifically for erosion control and revegetation benefits.

The engineered fibers have thousands of microscopic barbs that interlock with one another within the matrix. This feature contributes to intimate contact between Curlex products and underlying soil. In addition, Curlex fibers expand when wetted during hydraulic events, which cause the fibers to dig and anchor themselves into the soil. Another added benefit to the Curlex fiber matrix is that it provides ideal ”greenhouse-like” growing conditions for seeds, which results in enhanced germination for increased vegetation establishment. Curlex is considered the industry standard by many because of the plethora of Curlex Features and Benefits.

Responsibly Sourced and Environmentally Friendly Curlex Great Lakes Aspen Excelsior.pdf

Straw and Coconut Fibers

AEC Premier Straw consists of agricultural straw that is certified weed seed-free. Agricultural straw fibers are commercially grown in the United States.

AEC Premier Coconut consists of top quality coconut fibers. It should be noted that most, if not all, coconut fibers for use in the erosion control industry are imported fibers, so they are not native to the United States.

AEC Premier Straw/Coconut is a blend our AEC Premier Straw and AEC Premier Coconut fibers.

Functional Longevity

All degradable fiber matrices break down; however, some degrade in place faster than others. Functional longevity of ECBs varies because of differences in climatic conditions. In general, straw ECBs have functional longevities of ≤ 12 months, Curlex ECBs 15-36+ months (depending on the product selected), and coconut ≤ 36 months. Straw fibers are flat by nature and do not naturally form an interlocking matrix so, after the netting material degrades, essentially unanchored blown straw remains on the soil surface. On the other hand, Curlex fibers are engineered to be curled fibers with soft barbs that provide a continuous, interlocking matrix even after the net material degrades. Straw/coconut products are typically 70% straw and 30% coconut fibers by weight. Thus, if the functional longevity of straw is ≤ 12 months, approximately 70% of the straw/coconut product will be gone in less than one year.

It is important to consider how long the ECB is needed or desired to be on the site(s). Some projects may want or need the biodegradable product to degrade in one growing season, but other projects may desire a product that lasts two to three growing seasons. In general, product performance capabilities, climatic conditions, and estimated vegetation establishment rates of selected species dictate the type of ECB selected for environmentally sensitive jobs.

Environmentally Sensitive Areas Must Demand Biodegradable Anchors

American Excelsior Company’s E-Staple shall be installed to anchor ECBs for a complete 100%, biodegradable solution to your environmentally sensitive projects. E-Staples shall be utilized to anchor the biodegradable ECBs in place. E-Staple will completely degrade in 8 to 24 months as compared to common steel staples that will still be in the soil several years after installation. E-Staples are a ”natural plastic” derived from plant sugars and oils, which allows them to biodegrade in soil. Natural plastics eliminate the use of petroleum-based materials, which ultimately helps reduce our dependency on oil.

Trout streams, lakes, and ponds are home to a diverse ecosystem that needs a system in place to protect all aspects of wildlife. Such a system necessitates a properly designed SWPPP that considers the protection of snakes, endangered frogs, and other wildlife species. Sediment-laden runoff entering streams can kill aquatic species; using 100% biodegradable erosion control products for project applications can greatly reduce instances of sediment loads entering our precious waters.

Bindex BFM

Bindex BFM is a one-step erosion control system that provides intimate protection. Bindex BFM combines natural wood fibers, including Curlex fibers, with a cross-linked binder, tackifier, and dye that is mixed with water and applied hydraulically. The resultant matrix becomes water-insoluble, allowing for maximum protection and effective germination immediately after drying.

All ingredients are pre-measured into each bag of Bindex BFM. This one-bag system reduces inventory needs, simplifies compliance, allows for convenient mixing, and helps to ensure consistent quality.

Bindex BFM Highlights

Hydraulically applied slurry ”binds” to almost any soil surface and dries to form a bonded fiber matrix that can be hydrated repeatedly

Matrix helps reduce surface erosion by holding soil, seed, and amendments in place while promoting vegetation establishment

Matrix protects from rainfall and wind erosion while releasing moisture to the soil below it

Made from wood fibers (including Curlex fibers), a natural binding agent, and a mixture of organic and mineral activators

Formula is non-toxic and biodegradable (see Bindex BFM Fish Toxicity Report)

Self-contained one-bag system

Does not require two-step application

how easily Bindex BFM with Curlex Fibers mixes with mechanically agitated hydroseeders (Bindex BFM is not designed to be installed with jet agitated equipment).

In addition, watch how Bindex BFM sprays uniformly from a mechanically agitated hydroseeder.

VIDEO: Straw Vs. Curlex®

Curlex® is considered the industry standard by many because of the plethora of Curlex® Features and Benefits. Remember, there is only one Curlex®. Accept no imitations.

American Excelsior Company is the inventor of biodegradable erosion control blankets. Developed in the early 1960s, Curlex® excelsior blankets are specifically designed to actually promote ideal growing conditions for grass seed, while simultaneously protecting topsoil from wind and water erosion. Curlex® excelsior blankets have long passed the test of time. By design, Curlex® blankets have a built-in swell factor — wet curled excelsior fibers slightly expand in thickness and interlock to form a strong, fiber matrix. This allows the fibers to provide intimate contact with local terrain. Water flow is trained to follow the curled fiber matrix. The roughness of the curled excelsior matrix slows the velocity to a point where gravity takes over, which allows moisture to slowly seep into the topsoil to promote ideal growing conditions.
Typical Applications

Highway embankments, ditch bottoms and slopes, bridges, approaches, and medians

Residential, commercial, & industrial developments

Urban drainage, stream banks, and waterways

Golf course fairways, roughs, waterways, & drop structures

Landfill caps, side slopes, and let down structures

Pipeline right-of-ways
Material Characteristics

Curlex blankets consist of unique softly barbed, interlocking, curled, Aspen excelsior fibers. They are naturally seed-free. Curlex blankets are available with a variety of environmentally sensitive and/or stronger netting types to match job site requirements. We offer a green color-coded plastic netting for applications requiring UV resistance, strength, and longevity. Our photo-degradable Quick Mow^™ netting is recommended for urban, golf course, and certain roadside projects. It is color-coded (white) to identify it as a rapid breakdown, polypropylene netting designed for use in areas to be mowed. Also available is our FibreNet^™ — 100% biodegradable netting — for use in critical environmentally sensitive areas.

Most straight-line fiber blankets draw the line at 270 g/m² (.50 lb/yd²), but not Curlex. At just under 400 g/m² (.75 lb/yd²), Curlex blankets bring 50% more erosion control fibers to your job site. Curlex blankets are available in natural Aspen or QuickGRASS^® (green). Combine that with a roll that is wider than conventional blankets and you have today’s most effective and efficient multi-purpose biodegradable erosion control blanket. Curlex excelsior blankets are available individually wrapped or in master packs to allow for mechanical unloading and stacking.

Curlex® CL Blankets
Curlex® CL Blankets

If you can get a Performance Driven Product like Curlex^®, why would you use anything else?

Innovative erosion and sediment control solutions are the norm at American Excelsior Company because our Curlex fibers are the backbone of our products. Curlex fibers have a unique ability to expand and contract when wet and when combined with ”barbed” fibers, Curlex CL fibers actually cling to each other. Project owners, consultants, specifiers, and landscape contractors wish to have many choices when selecting erosion control blankets (ECBs).

That is why American Excelsior Company, the inventor of biodegradable ECBs, innovated Curlex CL, which is a cost-effective lighter version of standard Curlex that provides performance and vegetation establishment benefits superior to straight lined fiber blankets such as straw. Curlex CL offers the best of both worlds – all the unique benefits of the time proven Curlex fiber and a competitive price. Curlex CL is your new solution for a basic single net and double net ECB applications. Curlex is considered the industry standard by many because of the plethora of Curlex Features and Benefits. Learn more about the differences amongst various fibers used for erosion control.

Curlex® SiltTRAP™
Curlex® SiltTRAP™

Dirty water and mud washing into the streets – these are a few things on construction sites that pose such a nuisance and, at the same time, such a difficult challenge to control. However, ignoring it is simply not an option.

Today’s contractors and engineers are faced with stringent EPA water quality discharge requirements, including NPDES Phase I and II regulations and increased enforcement on job sites. Curlex® SiltTRAP™ was developed to help meet regulatory compliance standards by filtering out sediment from runoff water before it enters storm drains in construction areas.

In addition to the compliance requirements, new residential and commercial developments can enhance the appearance of their projects, while solving problems of soil loss and water runoff by using Curlex® SiltTRAP™. Since these developments are designed to attract buyers or tenants while under construction, it’s vital to the owners to employ an aesthetically pleasing approach to their projects. The green color gives the appearance of instant natural turf, masking its real purpose of providing erosion control for soil loss and water flow control.
Typical Applications

Along back edge of curbs and gutter structures

Along edge of concrete and asphalt pavements

Perimeters of residential construction sites

Perimeters of commercial construction sites

Perimeters of industrial construction sites
Material Characteristics

SiltTRAP offers a unique way of installing a temporary buffer strip to capture sediment before it washes away, filling gutters, clogging pipes, and generally creating a mess. The naturally seed free, unique Curlex^® excelsior fibers in SiltTRAP filter soil from the runoff and greatly reduce off-site problems without the installation and disposal hassles of silt fence. All components of SiltTRAP are degradable, thus there is no need to remove the product after the construction phase is complete.

Curlex SiltTRAP with its QuickGRASS^® (green pigment) fibers provides a tremendous visible benefit that is seen the moment it is installed. This is well received in residential and commercial areas where you want to promote a finished effect when your visitors are entering or leaving the site.

Curlex SiltTRAP fibers expand when wet creating a ”clinging” effect to the soil, making the blanket become twice as thick, thereby adding additional protection during heavy rain. The same fibers then slowly release the absorbed moisture back to the soil creating a hygroscopic action that nurtures seeds and promotes revegetation.  Watch the Natural Mechanical Functions of Engineered Curlex Fibers.

Curlex^® and AEC Premier Straw^® products – led by Curlex^® CL ECBs and Curlex Sediment Log^®

Curlex fibers are cut from logs using a unique process where the actual thickness of the fiber, as well as the width, can be cut on high-speed equipment at the same time. The process is so unique, we can control the width and thickness down to the thousands of an inch. Curlex technology yields engineered fibers designed specifically for erosion and sediment control products.

Curlex CL technology utilizes less overall raw material, while still providing a high level of performance. All Curlex raw materials are provided by members of Sustainable Forestry Programs, thus we ensure our Curlex products are sustainable from the very beginning.  Please visit our Curlex CL webpage for more details. Curlex is considered the industry standard by many because of the plethora of Curlex Features and Benefits.

Straw fibers are by-products of agriculture processes and do not provide the level of erosion or sediment control protection that can be expected with engineered Curlex brand products. However, straw fibers are sustainable because as long as the agricultural crops, such as wheat, are needed the straw fiber by-products will be available for lower end erosion and sediment control products.

Curlex Sediment Log is a unique product designed to be porous, unlike many other dense products that only provide damming effects. The key of Curlex Sediment Log is its fibers. Curlex fibers have been shown to be highly effective at filtering contaminated runoff. For example, independent research has quantified Curlex fiber’s unique capability to remove even polynuclear aromatic hydrocarbons (PAHs), which are typical components of asphalts, fuels, oils, and greases. It is important to remember that contaminated runoff cannot be filtered if it is not able to flow through the BMP. The porous design of Curlex Sediment Log allows water to flow through them. Curlex Sediment Log also dissipate flow velocity, which causes sedimentation in front of the products.  Another very important property of Curlex Sediment Log is that it does not contain any seeds – period. Curlex Sediment Log is made from clean, 100% seed free Great Lakes Aspen. Other BMPs, such as straw based products, may be certified free of ”noxious” weed seeds.  ”Noxious” weeds vary by region so take the safe route with naturally seed free Curlex Sediment Log and ensure no seeds will be introduced into the environment on your next project. Please visit our Curlex Sediment Log web page for more details.

Environmentally Friendly

Our Environmentally Friendly products are led by erosion control blankets with netting technologies provided by Conwed.

As discussed above, Curlex fibers are engineered specifically for erosion and sediment control solutions. During the precise process, curls and barbs are created that allow the

fibers to interlock with one another to form a continuous matrix. The interlocking fibers allow for Nature Zone^™ netting materials with larger openings to be used, which have been shown through University testing to be more wildlife-friendly than nets with smaller opening sizes. Other fibers used for erosion and sediment control, such as straw, do not interlock so they typically fall through nettings with larger openings. Thus, fibers other than Curlex generally utilize net materials with smaller openings to hold the product together.

Curlex^® NetFree^™ is very Environmentally Friendly too because it is the only erosion control product that does not contain any netting and the entire product is 100% biodegradable. For complete details, please visit our Curlex NetFree webpage. Many of our products are also available with Environmentally Friendly jute netting and can be viewed at the link below.

100% Biodegradable

Please visit our web page on all our 100% Biodegradable Erosion Control Options.

Recycled Products

Recyclex TRM and Recyclex TRM-V and permanent turf reinforcement mats (TRMs) whose fibers are made from 100% post-consumer goods. For every one pound of Recyclex fibers, approximately 20 plastic bottles are diverted from our landfills. In many cases, Recyclex fibers are used to permanently protect landfills instead of the bottles being ”thrown away” in them. Recyclex products provide a high level of permanent erosion control protection while helping the environment at the same time.  Avoid the requirement for producing new materials used by other TRMs and make a green footprint on your next project by selecting our environmentally responsible Recyclex TRM or TRM-V.  Just think, you make a difference each time you use Recyclex products. For complete details, please visit our Recyclex TRM and TRM-V webpage.

LEED® Points

American Excelsior Company is your single source for earning LEED points outside your building. Our Eco-Sustainable product line has been developed to help site owners earn LEED points. Our products can help contribute toward U.S. Green Builders Council’s Leadership in Energy and Environmental Design (LEED) Green Building Rating System^™ points to help your project achieve its LEED certification.

Many of our products can help contribute to your LEED certification. For example, Recyclex TRM and TRM-V can be an integral part of your LEED certification by helping achieve up to 10 LEED points.

Pikeview Quarry Reclamation with Curlex II FibreNet
The Pikeview Quarry in Colorado Springs, CO was the site of a 115 year-long limestone mining operation.
After its closure, project personnel needed a proven erosion control blanket solution that could protect
and revegetate the Quarry’s numerous long and steep slopes. Over 422,000 yd2 of Curlex II FibreNet were
installed on the project.
https://youtu.be/DTlIruVp72g

Installing Curlex® Blankets in a Channel
Follow these steps to ensure that your Curlex blanket is installed correctly in channels. Proper trenching,
overlap and stapling are key to a successful installation.

Installing Curlex Blankets on a Slope with Trench Methods A & B
During installation of Curlex Blankets the start of the roll needs to be installed in a trench or rolled 3 feet
over the crest of the slope. This video details Trench Method A & B used in installing Curlex Erosion
Control Blankets.
https://www.youtube.com/watch?v=jGBbtKmUdtU

Revegetating Waterways with Curlex ECBs
Several agricultural swales needed to be remediated to avoid losing valuable crop soils to flood events.
Curlex II was chosen to revegetate and protect the swales because it keeps soil and seeds in place, even
during adverse weather conditions. Mechanically automated unrolling and stapling devices were used to
install Curlex II in an efficient and effective manner.

Curlex® vs Straw in a Channel
Should erosion control blankets stay in contact with the soil? We think so. Curlex fiber blanket does not
float with channelized sheet flow, but straw blankets float losing intimate contact with the soil surface, so
you lose soil.
https://www.youtube.com/watch?v=dQFhbgRduW8

Comparing ECB Fibers on Bulldozer Tracks
How well an erosion control blanket (ECB) performs in the field depends heavily upon the type of fiber
contained in its matrix. Uneven ground surfaces at jobsites that utilize heavy machinery and moisture from
the environment present two formidable challenges to the effectiveness of ECBs. So, how do commonly
used ECB fiber types respond when exposed to moisture on such surfaces?
https://youtu.be/vpldgDhwLMg

Curlex® Fiber Natural Mechanical Functions
As Curlex fibers are wetted, they swell and dig into the soil. This “Velcro-like” connection reduces soil
movement during erosive events, keeping soil, seed, and fertilizer in place. This allows seeds to germinate
and vegetation to be established, which helps prevent future erosion.
https://youtu.be/G_Rg180IyV0

Creating Grassed Waterways with Curlex® Erosion Control Blankets
Grassed waterways are vegetated channels used to reduce erosion, improve sedimentation, and remove
pollution from surface waters. Using PAH-sorbent Curlex® blankets in constructing grass waterways is a
natural solution that allows vegetation to grow quickly and minimizes the effects of erosion on the
landscape.

Curlex® SiltTRAP™
Keep the soil on your site and off of the road with Curlex SiltTRAP. Curlex SiltTRAP provides an aesthetically
pleasing green color for a clean, finished look for your development. Curlex SiltTRAP is made with proven
Curlex engineered fibers.
https://www.youtube.com/watch?v=7f_Y1qjGg68

Curlex® Hi-Vis Excelsior Logs™
Hi-Vis excelsior logs, made with proven Curlex excelsior fibers, are a highly visible and durable solution for
those who desire controlled site access and perimeters around the jobsite. Polyethylene handles
integrated into each log’s casing permit ease of transport and stacking, allowing personnel to arrange
easily arrange and rearrange them. The Curlex fiber matrix also allows hi-vis logs to act as a
complementary sediment control BMP.
https://youtu.be/Hf3KOmfePLI

Filtering vs Damming Comparison Using ASTM D5141
The flow rate of water through two sediment control devices with different fiber types is compared using a
ASTM D5141 test apparatus. This comparison is one way to illustrate the difference between a “filtering”
and a “damming” sediment control device.
https://youtu.be/pFIAq-aQMuc

Curlex® Sediment Log® Flow Through vs. Straw Wattles
One of the uses of Curlex Sediment Logs is to install them in ditches. Curlex Sediment Logs will slow water
velocity and filter out sediment as ditches fill with storm water. Straw Wattles are dense and do not allow
water to flow through them.
https://www.youtube.com/watch?v=PZ0DxDT9RTM

Curlex® Sediment Log® Installation Over Curlex®
Curlex Sediment Logs are a terrific addition to any channel project. They reduce velocity and capture
sediment and other contaminants in the water. Installation is easy, just follow these simple steps.

Does Your TRM Float During Hydraulic Events?
Surprisingly, several turf reinforcement mats (TRMs) available today float in water. Floating TRMs allow
water under the TRM between anchoring devices during hydraulic flows, which leads to erosion. Intimate
contact with the subgrade is critical to successful erosion control applications that use TRMs. Would you
rather have your TRM floating or intimately contacting the subgrade during a hydraulic event? American
Excelsior Company’s Recyclex® family of TRMs do not float in water.
https://youtu.be/-fp97RRHbCU

TriNet Recyclex TRM Soil Fill Installation
A soil fill turf reinforcement mat (TRM) installation involves placing additional soil, seed, and soil
amendments on top of the TRM after it is installed. Then, a degradable erosion control blanket (ECB) is
installed over the seedbed to provide protection and encourage the vegetation’s roots to grow down
through the TRM and reinforce the root mass, an effect known as root reinforcement.
https://youtu.be/RhImLmbG1Ks

Recyclex TRM – V Creating Vegetated Channels to Protect Fly Ash Landfill
When an Illinois power plant was decommissioned, two fly ash landfills had to be capped. The runoff from
these areas would be significant and there were many sensitive waterways in the immediate area that
required protection. Recyclex TRM – V was chosen to create the vegetated waterway around the closed fly
ash ponds. These vegetated waterways allow for better water infiltration and filtration than rip rap. The
vegetated areas are important to wildlife and return the site to more natural conditions. Additionally, the
installation of a turf reinforcement mat (TRM) is less expensive than rip rap.
https://youtu.be/SwgF3Hf1sWk

Recyclex® TRM-V Protects Channel During Multiple Large Storms
Recyclex TRM – V protects a drainage channel hit by multiple storms in just a few days. Water flows send
massive amounts of debris through the channel and Recyclex TRM – V holds up.

Curlex® Bloc Installation
Curlex Bloc are manufactured in the U.S.A. with native Great Lakes Aspen fibers, an alternative to coir logs.
The Curlex fiber matrix is naturally seed free and nontoxic. The standard 100% natural biodegradable
containment material is designed to start degrading during the first year to allow voluntary seed and
sediment into the Curlex fiber matrix. Applications include shoreline erosion, sediment, and perimeter
control, and around inlets or outlets. This video demonstrates installation for a shoreline application.
https://www.youtube.com/watch?v=D8b3B3XbE7o

Fly Ash Slurry Filtration Using Curlex® Bloc
Fly ash samples were collected from a coal plant in Ohio. Channel simulators were built to determine the
reduction of total suspended solids (TSS) and turbidity of fly ash slurry exposed to Curlex Enforcer® and
Curlex Bloc over a ninety-minute period. The results were remarkable.
https://www.youtube.com/watch?v=Ohp3i723PN8

Curlex® Enforcer® and Curlex® Bloc Filter Station Simulation
All natural Curlex Blocs are very effective at removing fine sediments and other contaminants from runoff.
Typically, flocculants have been used to remove these fine particles. A series of Curlex Bloc Filter Stations
can be a valuable tool to help improve water quality without adding chemicals into the environment. See
first-hand in this video how well the Curlex Bloc Filter Station works without the aid of chemicals. The
channel was lined with Curlex Enforcer then the Curlex Bloc Filter Station was installed into the channel. A
slurry of premixed sediment-laden water was added to the channel over the course of the four-hour long
simulation.

FAQs

What Is Curlex®?

Curlex is perhaps the most studied, and unique erosion and sediment control fiber today. Curlex comes in many forms for erosion control, sediment control, and revegetation purposes. The most common form comes in roll form, which may be referred to as Rolled Erosion Control Products (RECPs), Erosion Control Blankets (ECBs), or simply blankets. Curlex also comes in tubular Curlex Sediment Log® form. Our latest innovation of Curlex is the Curlex® Bloc. The key to any version of Curlex is the Curlex fiber itself, which leads to superior performance-based results. Unlike other fibers, Curlex fibers have natural mechanical functions. Curlex excelsior products promote ideal growing conditions for seed, while simultaneously providing protection from wind and water erosion. Curlex is engineered specifically to yield ideal performance results with its curled interlocking soft barbed fibers that create a strong, multi-directional fiber matrix. Beyond superior erosion control, sediment control, and revegetation, Curlex fibers also remove oil from water. Read more about the Features and Benefits of Curlex. The word “Curlex” has become synonymous with various erosion control materials, but don’t be fooled by imitators. There is only one Curlex.

Why is Curlex® SUPER?

Sustainable Curlex^® fibers offer Unique characteristics, delivering high Performance through their expertly Engineered features. American Excelsior Company offers the support and Resources you need to make your project a success.

SUSTAINABLE – Curlex^® is made from renewable, sustainably harvested Great Lakes Aspen, native to North America. The trees used to produce Curlex^® fibers are harvested near our manufacturing facility in Rice Lake, WI, which minimizes our carbon footprint. Aspen trees are a fast-growing species and are self-propagating. Aspen stands at various stages of their life cycle are key to several wildlife species such as grouse and elk. The largest living organism in the United States is a stand of aspen in the western U.S.

UNIQUE – Curled, barbed Curlex^® fibers expand and contract during hydraulic events, digging into the subgrade and forming a “Velcro-like” connection. Unlike blankets made with straw fibers, properly installed naturally seed-free Curlex^® blankets will not float. Curlex^® fibers slowly release moisture into the soil, creating a “greenhouse effect” that sup ports vegetation establishment. Curlex^® blankets are also available with a non-toxic green pigment that can be added to the fibers for an aesthetically pleasing, finished appearance.

PERFORMANCE – Erosion and sediment control products made with Curlex^® fibers reduce job site risk and help you stay in compliance. Doing it right the first time means lower lifetime project costs and higher profits. All performance-based Curlex^® products are quantified by large-scale ASTM testing and have decades of proven field success. In addition to holding soil in place and fostering ideal seedbed conditions for vegetation, Curlex^® fibers effectively remove polynuclear aromatic hydrocarbons (PAHs) and heavy metals from contaminated stormwater.

ENGINEERED – Engineered and designed for erosion and sediment control products, Curlex^® fibers create a bond so strong that netting is not required as proven by the industry’s most environmentally friendly, 100% biodegradable Curlex^® NetFree^™. Only sourcing Aspen fibers means that Curlex^® fibers do not contain pitch or resin, so they produce naturally clean fibers. Unlike straw, an agricultural byproduct, Curlex^® fibers are designed to provide a superior roughness factor (Manning’s n) to slow water velocity and resist shear forces.

RESOURCES – Curlex^® is manufactured by American Excelsior Company^®, which has been in business since 1888. Our team of experts on erosion and sediment control, stormwater, and revegetation applications is here to help. Curlex^® is backed by the industry’s largest privately-owned test facility – ErosionLab^®. We provide excellent service anywhere in the U.S. with our multiple manufacturing plants, warehouse sites, and extensive distribution network. This ensures that technical assistance and our products are always close at hand.

Where Do Renewable Curlex® Fibers Come From?

Engineered Curlex^® fibers are made from renewable Great Lakes Aspen trees. All raw materials for Curlex^® are purchased from members of sustainable forestry programs. The raw material is engineered into specific cuts of Curlex^® fibers that have been designed specifically for erosion control, sediment control, and revegetation benefits.

Responsibly Sourced, Environmentally Friendly, and Sustainable

What Is Excelsior?

Excelsior is shaved wood fibers. Excelsior is a Latin word meaning “always upward.” However, American Excelsior’s has a unique way of curling the fibers with small “barbs” which allows the stands to cling to one another and other objects such as soil when used for erosion control applications. Some excelsior may not contain these features so be sure to ask for “Curlex^®” when quality is important.

What Does ECB Stand For?

ECB stands for Erosion Control Blanket.

What are Some Basic Differences Between Blankets and Mulch Products?

Water flows across the tops of blankets because the physical strength provided by the mechanically stitched bonded products are designed to hold together when water flows over them. However, mulch options (hydraulic and dry) that rely on chemical bonds are designed to mainly absorb precipitation because they don’t have enough physical strength to hold together when water flows over them. That is a main reason why we see blow outs when concentrated flow occurs over mulches. Failures with mulch products are also common when the water holding capacity of mulches and/or soil is exceeded on slopes (the mulch and/or soil slump away after an unstable condition is created by the heavy, saturated mulch and/or soil on the surface). High water holding capacity is a property that is intentionally encouraged by some mulch product designs, even though it can lead to slip planes and mass wasting, which is a roadside safety concern and typically leads to environmental contamination. Any perceived monetary savings are quickly lost when having to mobilize multiple times to reapply product to address failures. Doing it right the first time with the proper Curlex^®, Recyclex^®, and/or TriNet^® engineered solution commonly saves everyone time and money.

Does The Type Of Degradable Fiber Within The Matrix Of An Erosion Control Blanket (ECB) Make A Difference?

The type of degradable fiber within the matrix of an ECB can mean the difference between a successful application and a failure.

What Is The Difference Between An Erosion Control Blanket (ECB) And A Turf Reinforcement Mat (TRM)?

ECBs are temporary products that are designed to provide erosion control and hasten vegetation establishment. ECBs are used in applications where the resultant vegetation alone will be able to withstand design hydraulic forces. TRMs are long-term solutions that provide erosion control and hasten vegetation establishment, but they also provide long-term reinforcement to the vegetation. TRMs are typically used in applications where the resultant vegetation alone will not be able to withstand design hydraulic forces.

What Does TRM Stand For?

TRM stands for Turf Reinforcement Mat.

What Is The Difference Between Stem Reinforcement And Root Reinforcement By Turf Reinforcement Mats (TRMs)?

Stem reinforcement occurs when vegetation grows up through TRMs so the stems are reinforced by the TRM. Root reinforcement occurs when vegetation grows down into TRMs so the root mass is reinforced by the TRM. Typically, stem reinforcement results from stand alone applications (seed is applied to soil then TRM is rolled over the seed) and root reinforcement occurs from soil fill applications (TRM is rolled out, soil is placed on top of the TRM, soil-filled TRM is seeded, entire system is covered with a degradable Curlex^® Erosion Control Blanket (ECB)). American Excelsior Company does not require soil filling with any of our TRMs, but occasionally Designers specify the soil fill installation method.

Do American Excelsior Company Turf Reinforcement Mats (TRMs) Have To Be Soil Filled?

American Excelsior Company does not require soil filling with any of our TRMs, but occasionally Designers specify the soil fill installation method.

What Is Recyclex®?

Recyclex® is a family of performance based environmentally friendly Turf Reinforcement Mats (TRMs). Recyclex® fibers are made from 100% recycled materials – such as soda bottles. Recyclex® TRM products are commonly used towards LEED® Credit(s) 4.1/4.2 amongst other credits. Our LEED® Brochure provides more information regarding potential credit contributions. Recyclex® TRM is arguably the most tested TRM ever. Recyclex® products provide superior performance capabilities for slope and channelized flow applications. Unique Recyclex® products do not float in water. Amazingly, several TRMs on the market today do float in water, which can lead to erosion during hydraulic events.

What Is QuickGRASS®?

QuickGRASS® is a Rolled Erosion Control Product (RECP) option manufactured by American Excelsior Company that is pigmented green. QuickGRASS® RECPs are green in color, which presents a finished, vegetated look until seeds germinate and plants replace the biodegradable matrix of the Curlex® product.

What Is FibreNet™?

FibreNet™ is netting used on American Excelsior Company Erosion Control Blankets (ECBs) that is a biodegradable jute netting option.

Does Curlex® NetFree™ Really Contain No Netting Material?

Curlex® NetFree™ contains biodegradable Curlex® fibers and biodegradable thread material. To our knowledge, Curlex® NetFree™ remains the only biodegradable Erosion Control Blanket (ECB) that does not contain netting material. Curlex® NetFree™ has become a very popular product of choice.

Where Do Straw Fibers Come From?

Straw fiber is an agricultural by-product. After the grain, such as wheat, has been harvested from the plant the stem of the plant is cut. The straw stems are baled then brought to an Erosion Control Blanket (ECB) manufacturing facility where they are “busted” apart before being distributed into an ECB. No engineering goes into straw fibers so their erosion control, sediment control, and revegetation capabilities are limited as compared to Curlex® fibers.

What Is QuickMOW™?

QuickMOW™ is netting used on American Excelsior Company Erosion Control Blankets (ECBs) that is color coded white. QuickMOW™ netting is a rapid degrading netting option.

Why Is NatureZone™ Netting Used On Curlex Erosion Control Blankets (ECBs) Better For The Environment?

Curlex® I CL, II CL, I, II, I .98, & II .98 products are available with environmentally friendly NatureZone™ Netting. NatureZone™ netting contains the industry’s largest net openings, which have been proven effective at minimizing potential entrapments. Other ECBs available (straw, straw/coconut, coconut, etc.) have to use netting with smaller openings sizes otherwise the shorter fibers would fall out of the product. Unique Curlex® fibers cling and barb together, which allows net openings to be very large and environmentally friendly. Unlike other fibers, Curlex® does not need netting to hold it together as is evident with Curlex® NetFree™.

Where Do Coconut/Coir Fibers Come From?

Coir is fiber that comes from the husk of a coconut. No engineering goes into coconut fibers so their erosion control, sediment control, and revegetation capabilities are limited as compared to Curlex® fibers. Coconuts do not naturally grow well in North America, thus coir products are commonly from South Asian countries such as Sri Lanka, India, Pakistan, Bangladesh, Bhutan, Nepal, Maldives, Afghanistan, and Iran. The majority of coir imports into the U.S. come from southern India and Sri Lanka. Read more about potential concerns regarding imported coir based products.

What is American Excelsior Company Doing for the Environment?

AEC is providing a full line of natural, wildlife-friendly biodegradable Erosion Control Blankets (ECBs). There are no harmful chemicals, binders, crosslinkers or dyes containing toxic malachite green in our ECBs. Our industry-leading Curlex fibers within our ECBs are renewable, sustainable, and responsibly sourced. American Excelsior Company’s full line of Curlex^® FibreNet^™ ECBs are made with no plastic components.
AEC is providing fully natural Curlex® Sediment Log® and Curlex® SiltTRAP™ options to help eliminate over 36 pounds of plastic per acre of perimeter control. Biodegradable options from American Excelsior Company can eliminate over 36 pounds of plastic per acre of perimeter control (over 1,640 sixteen-ounce plastic water bottles) in appropriate applications when used in place of 2.1 oz/yd² silt fence fabric. Note: Be sure to always verify the requirements of each application before substituting any products.
AEC is providing Turf Reinforcement Mats (TRMs) with fibers from 100% post-consumer recycled goods. Recyclex® TRM family products help keep plastic out of landfills while providing high levels of erosion control and vegetation reinforcement. Proper TRM installations result in the product becoming part of the landscape. Benefits of cost-effective TRMs and vegetated channels over rock rip rap and other hard armors are plentiful.
AEC is providing Hydraulic Erosion Control Products (HECPs) without toxic malachite green in their tracer dyes. Some specifiers prohibit the use of toxic malachite green based on research because it puts organisms, fish, other wildlife, soil resources, and water resources at unnecessary risk when safer alternatives are available. Certified documentation from the manufacturer of tracer dyes (not the HECP manufacturer) shall be required confirming that the dye material does not contain any toxic malachite green.
AEC is offering Hydraulic Erosion Control Products (HECPs) in paper bags to eliminate over 310 pounds of plastic per load. A typical truckload of HECPs in plastic bags contains around 310 pounds of plastic packaging waste (over 14,200 sixteen-ounce plastic water bottles)!

Do Most Erosion Control Blankets (ECBs) Contain Seed?

No, most ECBs do not contain seed. Preseeded blankets typically work well only for local or site-specific applications. For example, ideal species in the Southwestern U.S. would likely be different than ideal species in the Northwestern U.S. Matching the proper seed mixture to a site is a very important component of successful erosion control applications using any ECB. Thus, American Excelsior Company defaults to local seed experts to determine the seed mixture that should be used in conjunction with our products.
