BioNet Short-Term Erosion Control Blankets

BioNet® Short-Term Erosion Control Blankets

BioNet^® Short-Term Biodegradable Erosion Control Blankets

The short-term biodegradable erosion control blankets in North American Green’s BioNet Series consist of an evenly distributed layer of 100% agricultural straw stitched with biodegradable thread to a single- or double-netting structure composed of 100% biodegradable jute fiber.

They are designed to provide all-natural erosion protection and assist with vegetation establishment for up to 12 months in applications such as moderately sloping areas and low-flow channels where bare-ground seeding and loose mulches often fail. After the blankets biodegrade, soil erosion is controlled by the root, stem, and leaf structures of the mature vegetation.
