Dead Main Foambag Stop-Off

The Dead Main Foambag Stop-Off System offers a fast, efficient method of sealing off areas of dead mains to prevent dangerous gas tracking.

The Foambag seals the empty space inside the main by introducing a special fabric bag into a main. Foam is mixed in a plastic container, poured into a cartridge gun and pumped into the Foambag. The foam swells to fill the bag and then oozes out through the semi-porous surfaces of the bag to roll any fluids, including water, out of the way. It then combines with any loose debris and bonds to the pipe walls. This produces a 100% seal in a predetermined short length of main in less than 30-60 minutes.
