Innovative erosion and sediment control solutions are the norm at American ExcelsiorCL_Page_Load_of_Curlex_CL Company because our Curlex fibers are the backbone of our products.  Curlex fibers have a unique ability to expand and contract when wet and when combined with "barbed" fibers, Curlex CL fibers actually CLing to each other.  Project owners, consultants, specifiers, and landscape contractors wish to have many choices when selecting erosion control blankets (ECBs).  That is why American Excelsior Company, the inventor of biodegradable ECBs, innovated Curlex CL, which is a cost effective lighter version of standard Curlex that provides performance and vegetation establishment benefits superior to straight lined fiber blankets such as straw.  Curlex CL offers the best of both worlds - all the unique benefits of the time proven Curlex fiber and a competitive price.  Curlex CL is your new solution to basic single net and double net ECB applications.  Learn more about the differences amongst various fibers used for erosion control.

Material Characteristics

Curlex CL blankets consist of unique softly barbed, interlocking, curled, Aspen excelsior fibers.  They are 100% free of any seeds.  Curlex blankets are specifically designed to promote ideal growing conditions for seeds, while simultaneously protecting topsoil from wind and water erosion.  Curlex blankets are designed with a built-in swell factor - wetCL_Page_Curlex_Fibers_Close_Up 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.  We offer a green color-coded plastic netting for applications requiring UV resistance, strength, and longevity.  Our photo-degradable QuickMow™ netting is recommended for urban, golf course, and certain roadside projects.  It is color-code white to identify it as a rapid breakdown, polypropylene netting designed for use in areas to be mowed.

Curlex CL blankets are offered in rolls that are longer than other standard blankets.  At a length of 150 feet, 33% more product makes it on each truck, which is imperative with the condition of today's fuel industry.  In addition, labor costs are reduced by expedited installation with longer rolls and because there are fewer seams to deal with.CL_Page_CurlexCL_on_Shoulder
