Triangular Silt Dike

Triangular Silt Dike is used as a barrier placed perpendicular to the flow of water. It is used to contain sediment laden water.

It is made with an inner triangular shaped urethane foam center and has an outer cover made from a woven geotextile. It also has protective aprons of either side of the dike to prevent both erosion and failure of the product.

Each dike has a 20” base and has a 10” height in the center. The apron extends beyond both sides of the triangle 2’. They are 7’ in length.

Several runs of Triangular Silt Dike being used in downtown Des Moines. Chosen for the small area to protect.	Close up view of the sediment contained behind the Triangular Silt Dike.
