BioNet Extended-Term Erosion Control Blankets

BioNet® Extended-Term Erosion Control Blankets

BioNet^® Extended-Term Biodegradable Erosion Control Blankets

The extended-term biodegradable erosion control blankets in North American Green’s BioNet Series consist of an evenly distributed fiber matrix that includes a long-lasting coconut fiber component for added durability and is stitched with biodegradable thread between 100% biodegradable jute fiber top and bottom nets.

They are designed to provide all-natural erosion protection and assist with vegetation establishment for 18 to 24 months, depending on the product, in applications such as steep slopes, medium- to high-flow channels, and shorelines. After the blankets degrade, soil erosion is controlled by the root, stem, and leaf structures of the mature vegetation.

Double-Net Straw-Coconut Blanket

SC150BN™ features a layer of 70% straw and 30% coconut fiber stitched with biodegradable thread between biodegradable, natural-fiber top and bottom nets. SC150BN™ is designed to provide erosion protection and mulching for up to 18 months in applications in which the strength of a double-net structure and the added erosion control properties of coconut fiber are required.
