This is a ‘Water Gate’ Barrier by Megasecur which provides instant flood control. It’s also portable dam that could save your home from flood waters.

This dam is super easy to install. To use it, simply unroll the water gate. The dam will then starts to expand and keep the water within the barrier.

This reuse-able dam will deploy as the flood is happening, and it only requiring a water current in order to work.

It’s a self inflating water gate system made from an ultra-strong, PVC-coated polyester fabric. The reusable dam might save you thousands of dollars from flood damage. Thanks to the inventor.
