Erosion Control

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.

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.

American Excelsior realizes project owners, consultants, specifiers, and landscape contractors wish to have a choice when selecting erosion control blankets. That is why American Excelsior Company, the inventor of biodegradable erosion control blankets (ECBs), manufactures straw, coconut, and excelsior blankets.

Our AEC Premier ECB manufacturing process starts with choosing only top quality, organic, agricultural straw fibers. A single or double net is then stitched to the topside or both sides of the ECB. Depending on your project requirements, several different netting types are available. We offer a green color-coded plastic netting for applications requiring UV resistance, strength, and longevity. Our photodegradable QuickMow™ netting is recommended for urban use and is a very popular choice for 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.

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.

Learn more about the differences amongst various fibers used for erosion control.

Curlex is considered the industry standard by many because of the plethora of Curlex Features and Benefits.

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.

E-Staple®
E-Staple®

A New, 100% Biodegradable Anchoring Staple

American Excelsior Company offers E-Staple^®, a 100% biodegradable turf staple, which is not just another turf staple. E-Staple is the result of years of research and development that has produced the most unique turf staples available today.
Typical Applications

Wetland and irrigation areas

Coastal projects

Golf course construction

Airport construction

Environmentally sensitive projects

Mowing applications

Use with Curlex^® NetFree™ for a 100% biodegradable project
Material Characteristics

E-Staple’s unique composition sets it apart from other 100% biodegradable staples. E-Staples are comprised of a natural plastic that originates from materials that are abundantly grown in the United States. E-Staple composition is Polyhydroxyalkanoate (PHA) plastic that is made from plant sugars and oils. ”Natural plastics” eliminate the use of petroleum-based materials, which ultimately helps reduce our dependency on oil. This innovative composition produces unique and unmatched physical and chemical features and benefits. All of these features and benefits, along with the independent pull out testing results vs. other turf staples, are detailed in the E-Staple TechNote.

Water resistant and do not soften from moisture during storage

Barbed shoulders and head for superior holding capabilities

More environmentally friendly than wire staples
Biodegradation

E-Staples biodegrade by a surface attack mechanism triggered by soil microbes naturally present in the soil. With this in mind, E-Staples will biodegrade faster in more fertile soil because that means there are more microbes breaking down the material. E-Staples biodegrade in cold (43 °F) to hot (180 °F) conditions and do not require a pre-hydrolytic reduction in molecular weight for degradation to begin. Pre-hydrolytic reduction generally requires a hot (140 °F – 149 °F) and moist composting step, which is not a common condition for soils where turf staples are used. E-Staples will biodegrade completely from the soil in 8-24 months depending on site conditions.
Packaging

Available in 4 and 6-inch lengths

Carton of 500 or 1,000
Installation and Staple Pattern Guidelines

E-Staples may be installed by hand; however, the E-Stapler™ mechanical applicator greatly expedites E-Staples installation and should be used for best results in hard soils.
