Erosion Control Overview

Have you ever wondered why Curlex® is so popular?

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

Erosion Control Blankets are thick, fibrous blankets woven out of either natural materials (e.g. straw and coconut fiber), synthetic materials (e.g. polypropylene) or a mixture of natural and synthetic materials. These blankets are used primarily to slow water runoff, provide effective sediment and erosion control, and enhance re-vegetation. These blankets are commonly applied to channel and ditch linings, slopes, culvert inlets and outfalls, riverbanks, and levees.

Erosion control blankets are classified as short term, long term, or permanent use, mostly based on whether vegetation is intended to replace or work in conjunction with the blankets.

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.

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® 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.
