Short-Term Photodegradable Erosion Control Blankets

Short-Term Photodegradable
Erosion Control Blankets

Our short-term photodegradable erosion control blankets are designed to provide erosion protection and promote vegetation establishment for 45 days up to 12 months, depending on the product. These blankets consist of an evenly distributed layer of 100% agricultural straw stitched to a single- or double-netting structure with degradable thread.

Short-term blankets are designed for moderately sloping areas and low-flow channels, where bare-ground seeding and loose mulches often fail. After the blankets degrade, soil erosion is controlled by the root, stem, and leaf structures of the mature vegetation.

Single-Net Straw Blankets

S75 and DS75 are constructed of 100% straw fiber stitched with photodegradable thread to a lightweight, photodegradable polypropylene top net. S75 is designed to provide erosion protection and mulching on moderate slopes and low-flow channels in low-maintenance areas for up to 12 months. Designed for high-maintenance areas where close mowing will occur soon after installation, the DS75 degrades within 45 days because of special additives in the photodegradable thread and top net that facilitate breakdown in sunlight.

Double-Net Straw Blankets

S150 and DS150 feature a 100% straw-fiber matrix stitched with photodegradable thread between lightweight, photodegradable polypropylene top and bottom nets. The double-net construction provides greater structural integrity than single-net blankets, for use on steeper slopes and in channels with moderate water flow. S150 is designed to provide erosion control and mulching for up to 12 months. Designed for high-maintenance areas where close mowing will occur soon after installation, the DS150 will degrade within 60 days because of special additives in the accelerated photodegradable thread and netting that facilitate breakdown in sunlight.
