C700BN Long Term Erosion Control Blanket consists entirely of coconut fibers manufactured into a matrix of uniform thickness and coverage. The coconut matrix is confined by a heavy woven coir fiber net on top and a biodegradable, jute/scrim net on bottom, mechanically (stitch) bound on two-inch centers with a biodegradable thread. C700BN is intended for slope and channel erosion control applications requiring up to thirty-six months of functional longevity. The material is fully degradable. The net, thread, and the fiber matrix is biodegradable. Actual field longevity is dependent on soil and climatic conditions. Each roll of C700BN is made in the USA and manufactured under Western Green’s Quality Assurance Program to ensure a continuous distribution of fibers and consistent thickness
