MegaSecur E.S. is the main manufacturer of Water-Gate dams.

Water holding back Water:  

The concept of the Water-Gate is simple - It’s the weight of the water that stops and contains the water. Its unique design allows the liquid to enter the PVC barrier and instantly stabilize it onto the ground - Just like a parachute deploys itself with the wind.

Simply unroll, unfold the first flap and let the PVC barrier deploys automatically as the liquid fills in. The Water-Gate dam will remain stable on any surface because it is made 4 times wider than its height and therefore can withstand 4 times more vertical than horizontal water pressure. 

Brands: The Water-Gate barrier is an "FM Approved" temporary and self-deployable dam considered as the most complete, easy to use and innovative anti-flood / emergency spill response system in the world.
