American Excelsior Company is the inventor of biodegradable erosion blankets. American Excelsior Company’s dedication to innovation has lead to the industry’s very first 100% biodegradable erosion blanket. Developed in 2003, Curlex NetFree excelsior blankets are specifically designed to actually promote ideal growing conditions for grass seed, while simultaneously protecting topsoil from wind and water erosion without the use of polypropylene netting on the top or bottom of the blanket. While maintaining all the benefits of the industry standard Curlex® excelsior blanket, Curlex NetFree offers a solution that eliminates the fear of plastic or jute netting getting caught up in moving activities or animals becoming entrapped in environmentally sensitive job sites.  Curlex is considered the industry standard by many because of the plethora of Curlex Features and Benefits.

Material Characteristics

Curlex blankets consist of unique softly barbed, interlocking, curled, Great Lakes Aspen excelsior wood fibers. They are naturally seed free. Curlex NetFree is a 100% biodegradable erosion blanket. Using the unique interlocking, curled, Great Lakes Aspen excelsior wood fibers stitched together with a 100% biodegradable thread allows the blanket to be manufactured without the use of plastic or jute nettings. Depending on job site requirements, the Curlex NetFree blanket can bring a higher performance characteristic to your job site over conventional mulch mats, blown straw with plastic netting, or other single net straight fiber blankets. Curlex NetFree excelsior blankets are available individually wrapped or in master packs to allow for mechanical unloading and stacking.

Curlex NetFree Case Studies

 

Curlex Netfree

A 100% biodegradable erosion blanket manufactured with an engineered cut of Great Lakes Aspen excelsior wood fiber. The wood fiber shall consist of 80% six-inch or greater in length. The blanket shall be of consistent thickness, with fibers evenly distributed throughout the entire area of the blanket creating a mat with no voids in material. The blanket shall be manufactured using a 100% biodegradable stitch material to form the continuous matrix of Curlex fibers. The blanket shall be naturally seed free and not contain any foreign weed seed, chemical additives, tackifiers, or paper products that could hinder grass growth, establish unwanted evasive weed species or shorten necessary erosion protection time periods. The blanket performance shall be supported by an ASTM protocol test result.
