Functions of Erosion Control Blankets          Pg.1, 2, 3  (next page)
 
Erosion Control Blankets (ECBs) are defined as roll-type materials designed to reduce seed and soil loss and aid in the establishment of vegetation. WEBTEC, Inc., offers a complete line of organic erosion control blankets ranging from lightweight straw blankets to heavier, slower degrading coconut blankets. Each blanket is stitched together using biodegradable thread and held together using photodegradable plastic netting. For longer-term protection TerraGuard Turf reinforcement mats, made from polypropylene, are also available.

TerraGuard erosion control blankets hold seed in place, while absorbing rainfall impact and wind forces. Their three-dimensional structure absorbs water while maintaining close contact with the soil. This provides the ideal environment for  seed germination and reduces the risk of burn-out after germination. The organic materials (straw or coconut) decompose as the vegetation matures, thereby providing the vegetation with necessary nutrients for growth. The blankets perform this in direct correlation with the site's ability to re-vegetate itself. In cool, dry places where vegetation grows slowly, the blanket will degrade slowly. In warm, moist areas where vegetation develops rapidly, the blanket will degrade faster. This process ensures the vegetation will receive nutrients as they are needed.

Importance of
Erosion Control

Global soil erosion destroys over 12 million acres of land each year. Nature slowly erodes itself. Human activities, such as construction clearance, greatly increase this process. The removal of vegetation exposes soil to the erosive forces of wind and water resulting in the loss of topsoil, minerals and nutrients. These losses result in costly cleanups and loss of land productivity. In the United States, The Environmental Protective Agency (EPA) has developed the National Pollutant Discharge Elimination System (NPDES) to help reduce the costs and environmental impacts associated with erosion from construction sites. Erosion control blankets have been named a Best Management Practice by the EPA in helping reduce soil loss and establish new vegetation.
