American Excelsior Company realizes project owners, consultants, specifiers, and landscape contractors wish to have a choice when selecting erosion control blankets (ECBs). That is why American Excelsior Company, the inventor of biodegradable ECBs, manufactures straw, coconut, and excelsior EBCs. Our AEC Premier Blanket manufacturing process starts with choosing only top quality, organic, weed seed free, agricultural straw fibers or top quality strands of coconut fiber.

pc_straw_4AEC Premier Straw/Coconut blend and AEC Premier Coconut ECBs are designed for mid to long-term erosion protection and vegetation establishment on slopes, channels, and shorelines. AEC Premier Straw/Coconut ECB combines 70% straw with 30% coconut to create a longer life ECB than standard AEC Premier Straw® ECBs. The AEC Premier Coconut ECB will provide a longer life, degradable ECB for severe applications or where special grasses need long-term protection. Both of these Premier products have longer duration photodegradable, UV enhanced nettings on both sides. Our FibreNet™—100% jute netting— is available for environmentally sensitive areas while maintaining performance standards.Material Characteristics

AEC Premier Straw/Coconut and AEC Premier Coconut ECBs are pc_straw_5degradable ECBs consisting of the finest weed seed free agricultural straw fibers and the highest quality strands of coconut fiber. By adding 30% coconut fibers to the AEC Premier Straw ECB, the straw/coconut blend of fibers can extend the degradable life up to 24 months depending on job site conditions. The Coconut ECB can provide longer erosion protection life up to 36 months depending on job site conditions. Lightweight and easy to handle, you can rely on AEC Premier Straw/Coconut blend and AEC Premier Coconut ECBs to provide a high degree of erosion protection and longer life than single or double net straw ECBs. AEC Premier ECBs are available individually wrapped or in master packs to allow for mechanical unloading and stacking.
