Quick Dam Flood Barriers, 3.5" Height, Black, 16 / Carton

Flood Barriers absorb, contain and divert problem floodwater to help protect your property from the dangers of flooding. They activate when wet and require no sand. Each 5' long barrier absorbs 4 gallons of water, swells to 32 lb. and expands to 3.5" high in 10 minutes. This compact, lightweight flood control is quick and easy to deploy. Flexible design conforms to shapes and can also be dragged for easy maneuverability. Inner absorbent turns to gel and creates a barrier. Dual-lobe chamber prevents rolling out of position. Leave in place for ongoing protection. Setup requires no additional tools or supplies. Barriers are safe, nontoxic and nonhazardous. Discard into regular trash when you no longer need them.
