Dewater Construction Sites with Silt Bags and Flocculants
Ground water accumulates on a construction site as a result of excavating, land moving and concrete cutting. Dewatering removes the collected water with pumps while silt bags and flocculants separate suspended solids from the water. Use silt bags and flocculants on their own or combine them for maximum efficiency.
Construction Dewatering Products

Dewatering Bags
Use a dewatering bag to pump silty water out of overly saturated construction sites. A dewatering bag is also known as a Silt Bag and a Pump Bag.
We refer to our own dewatering bags as Colonial Silt Bags. Colonial Silt Bags are manufactured from nonwoven geotextile fabric.
Flocculants
Use flocculants for construction dewatering to improve the sedimentation process. When properly administered, flocculants increase settling rates and remove contaminants like heavy metals and other pollutants. During the flocculation process, a flocculant binds to the contaminants in a body of water to improve the quality of the discharged water. Our flocculants include The Dirt Pill, Floc Bag, BioFloc™ and Floc™ Soc.
Dirt Pill
The Dirt Pill is a water-soluble tablet that improves the efficiency of construction dewatering.
Insert the tablet into a silt bag to flocculate sediment. When the Dirt Pill bonds to the sediment, the material coagulates and forms a mass. As a result, sediment is retained and filter water is discharged.
Floc Bag
The Floc Bag is a bagged flocculant that improves construction dewatering. Use the Floc Bag in ditch channels, retention ponds and sediment basins. The bag design ensures proper dosing at a controlled rate.
