When a flash flood occurs, response time is critical. The Water‑Gate™ flood dam can be quickly and easily deployed in three easy steps. The design uses the weight of the incoming floodwater to deploy and stabilize itself. Water enters and accumulates at the bottom of the barrier as the water level rises, causing the barrier to unfold and swell. The water pressure will open the dam and keep it in place, regardless of the nature of the terrain beneath the dam.
Step 1: Unroll the barrier. Step 2: Unfold the first fold. Step 3: Allow the water to accumulate inside.
It is as simple as that.
