Our Corewise sediment filtering bags are made of non woven geotextile designed to reduce the amount of sediments released from your saws. As water is expelled from your saw into the bag, sediment, silt, and sand is trapped inside. The water that was pumped into the bag is released through the bags’ filtering material as near-clear water. The Corewise sediment filtering bags are a cost effective solution to a variety of environmental applications. They are intended for one time use. Once the bag is full, the bag can be cut open and the waste can then be disposed of or reused on location.
