Quick Dam Water-Activated Flood Barriers are a faster alternative to sandbags — lay the flat bags around a door, garage opening, or basement entrance and they self-inflate to 3.5 inches when water hits them. Each 5-foot barrier absorbs up to 3.5 gallons, and the chained bags link end-to-end for long perimeters.
The 2-pack covers a 10-foot perimeter — enough for a single or double garage door or a walk-out basement entrance. No sand, no shoveling, no disposal headache after the storm clears. Once activated, the bags can be disposed of with regular yard-waste pickup in most areas, and unused bags store flat for years without degrading.
Quick Dam is an American manufacturer that produces its flood barriers in the United States. The company sells to FEMA, state emergency management agencies, and consumers who need a faster sandbag alternative for flash flooding, burst pipes, and basement seepage.
