Curlex® - The Original Erosion Control Blanket

 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.

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 siCurlex_Pond_Protectionte 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.
