Triangular Silt Dike

Silt Dike

triangular silt dikeThe Triangular Silt Dike is a synthetic alternative to standard coir silt checks or hay bales. Constructed using a combination of geotextile fabric and urethane foam, these silt dikes provide a more robust structure that can support continuous use in streams, channels, runoff ponds and other storm water collection areas.

Standard design of the silt dike features a triangular urethane foam placed inside of a geotextile fabric cloth. Along either side of the foam is an erosion control skirt that helps to prevent further erosion during currents or flows. Triangular Silt Control Systems can be used along perimeters or as silt checks to control erosion. For added support, U-shaped wire staples can also be used to secure the skirt or curtain into place.
