Silt Bags

Colonial Silt Bags (CSBs), also known as dewatering bags, are used to pump silty water out of a saturated area. Once the dewatering hose is connected, water, silt and sediment are pumped into the bag. While silt and sediment settle into the bag, filtered water discharges through the geotextile fabric. Colonial’s Silt Bags are highly efficient and VDOT Approved.

Sizes:
  • 4′ x 6′

  • 15′ x 15′
  • 15′ x 30′
  • 30′ x 30′

 

Dirt Pill

The Dirt Pill improves the efficiency of the Silt Bag. Add the 1 oz. water soluble polymer to the Silt Bag and watch as filtered water flows out the bag. The Dirt Pill acts as a flocculent, bonding to the sediment in the bag so that less silt escapes.
