Straw blanket is the most common erosion control blanket. This temporary erosion control matting is best suited for flat to mild slopes. When properly installed, straw matting effectively prevents soil loss in low velocity channels and mild erosion conditions.

Straw blankets protect grass seed and soil to create a stable network for seedlings to grow through. As seedlings grow through straw matting, the grass seed interlocks with the netting and stabilizes the soil.

Straw erosion blankets are manufactured with one (single) or two (double) nets which can be photodegradable or 100% biodegradable.

Secure straw matting to the ground with Sod Staples and install according to site specifications.

Coconut Erosion Control Blankets are made from exceptionally strong coconut fibers. Coconut fibers are much stronger than straw and excelsior fiber which is why coconut erosion blankets are rated for steeper slopes and higher channel flow.

All coconut fiber mats have two nets. The standard mats have two polypropylene nets and the All Natural blankets have 100% biodegradable jute netting.

Temporary Erosion Control Blankets | Short Term

Temporary Erosion Control Blankets are rolled erosion control products composed of natural fibers that are both photodegradable and biodegradable. Straw, Curlex® and jute netting all used to manufacture Temporary Erosion Control Blankets (ECBs). These rolled erosion blankets can last up to 12 months depending on material, application and installation.

Each material has unique qualities that determine the erosion blanket’s cost, degradability and ability to withstand erosion. Install temporary erosion blankets slopes with on 4:1 to 2:1 grade and low velocity channels.

Long Term Erosion Control Blankets

Choose Long Term Erosion Blankets for lasting erosion control and areas that need greater protection against wind and rain erosion. Although these blankets have strength and longevity, they are not classified as permanent turf reinforcement mats. Long term erosion control matting includes Straw/Coconut Coconut Blankets, and double net Curlex® blankets.
