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 for various erosion control materials, but don’t be fooled by imitators.  There is only one Curlex.

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 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.

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 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.  Learn more about the benefits of Curlex QuickGRASS.

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.

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.  Learn more about the Comparison of ECB Fibers.  Read about the Curlex® Features and Benefits that make it a superior erosion control, sediment control, and revegetation fiber.

What Does TRM Stand For?

TRM stands for Turf Reinforcement Mat.

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.  Read more about the unique properties of Recyclex products.  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.  Watch how you can easily check if TRMs float or sink in water.

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.

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 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.  Learn more about Ecologically Friendly Curlex Fibers.

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.
