American Excelsior Company—the inventor of the Curlex® brand and biodegradable erosion control blankets—has been the most trusted name in erosion control for since the 1960s.
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.

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.
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.
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.
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 permanent solutions that provide erosion control and hasten vegetation establishment, but they also provide permanent 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% post consumer goods – recycled 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.
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.
How Do I Know Which Product To Use For My Project?
