Construction site restoration is made easy with the use of temporary Erosion Control Blankets (ECBs).
Various degradable fibers such as straw, wood coir or degradable plastics are either woven or mechanically stitch-bonded to various netting materials, and then rolled for easy handling and deployment. Unlike loose fiber mulches, ECBs offer more dimensionally stable protection to better hold seeds and soil in place and encourage rapid growth. Wood or wire staples are used to secure the blankets to prepared and seeded soil. With the variety of nets and fibers available, applications range from low and moderate slopes to more demanding steep slopes and drainage swales.
Single and Double Net Straw ECBs
Single and double net straw ECBs are made with 100% straw fibers mechanically stitch-bonded to one or two photodegradable plastic nets. These are short term ECBs for use on low to moderate slopes with light runoff conditions. Each is available with a regular or rapid degrading net and thread, designed to degrade within 60-90 days of UV exposure, whereas the regular net can last for up to about 1 year.

Straw/Coir and Coir ECBs
Straw/coir and coir ECBs are extended term erosion control blankets. They are for more challenging sites with medium water runoff or where longer erosion prevention is needed. Coconut fibers, which are slower to degrade, are incorporated and mechanically stitch-bonded to two UV stabilized plastic nets. These blankets remain functional for up to three growing seasons, giving vegetation plenty of time to mature. Straw/Coconut ECBs are 70% straw and 30% coir and can remain effective for up to 2 growing seasons, whereas Coconut ECBs (100% coir fibers) can remain effective for up to 3 growing seasons.

Biodegradable Netting
Biodegradable netting is an option on the straw and coir ECBs. ECBs with biodegradable netting, as opposed to photodegradable plastic netting, are popular with urban projects near streams, rivers and lakes.
