US Erosion Wattles are made with 100% Certified Weed Free Wheat Straw, Excelsior, Coconut or Geotextile Fibers and are bound into a tight tubular roll. When Wattles are placed on the face of slopes, they intercept stormwater runoff, reduce its flow velocity, release the runoff as sheet flow, and provide removal of sediment from the runoff. By interrupting the length of a slope, the Wattle can also reduce erosion. Wattles are designed to stop sediment and other debris from entering retention ponds, lakes and other water bodies.
