Erosion control blankets (ECBs) are defined as roll-type materials designed to reduce seed and soil loss and aid in the establishment of vegetation. Hanes Geo Components offers a complete line of organic erosion control blankets ranging from lightweight straw blankets to heavier, slower-degrading coconut blankets. Each blanket stitched together using biodegradable thread and held together using photodegradable plastic netting. For longer-term protection, turf reinforcement mats made from polypropylene are also available.
