Silt Sack

Silt Sack

Silt Sack is made from a high strength UV stabilised polypropylene, and can be filled with a range of mediums including coarse sand, gravel or wood chips. Erosion Control Silt Sack can reduce sedimentation into combination curb and grate inlets. It is an important part of a comprehensive best management practice approach for site sediment control. 

Silt sack can trap the silt but allows water to pass into the sewer.
