Our barriers are versatile and reusable; Other than being used for emergency or flash floods, they are also used for damming, containing or diverting streams or ditches. Cities or environmental companies may use them for aquatic work in rivers, streams or ditches, protect substations, generators, and stations or across roadways to protect bridges and tunnels. Emergency spill response services often use the ones equipped with bottom release holes as an underflow dam for HAZMAT containment. Firefighting departments use it to create water reserves when fire hydrants are unavailable. Our FM Approved certification by FM Approval confirms our commitment in manufacturing top of the line products. We are now part of the National Flood Barrier Testing & Certification Program, the most recognized certification in our field. There is no assembly, filling or anchoring required. Simply unroll the barrier where needed, the flood waters come up onto the barrier, the weight of the water on the bottom tarp will hold the barrier in place and a strip of foam flotation in the upper layer will make the barrier rise to the water level. Multiple sections can be fastened together by using the pre-attached Velcro fastener system.
