Straw wattles help to stabilize slopes by shortening the slope length and by slowing, spreading and filtering overland water flow. This helps to prevent sheet erosion as well as rill and gully development, both of which occur when runoff flows uninterrupted down a slope. Stormwater runoff carries sediment and seeds off slopes as it gathers velocity, but Straw Wattles capture that sediment and hold it on site enabling seeds to settle and germinate, aiding the revegetation process.In addition, by filtering overland runoff and holding sediment on the slope, Straw Wattles help to protect lakes, ponds, rivers and streams from sediment pollution. They can also be used at perimeter areas of lots and construction sites as a sediment control method.
The wattles imitate natural stabilization by reducing rate of flow, absorbing water and filtering sediment runoff. By trapping silt and seed, the wattles allow native vegetation and brush to begin to revegetate and restore root integrity within one year. Stabilization of the hillside will eventually transition to the reformed growth as the Wattles decay. The wattles also form a durable containment area to prevent polluted runoff from reaching surface water.
Rice Straw Wattles replace Silt Fences, Sandbags, and Straw Bales with a natural, earth-friendly, weed-free solution.
