The world leader in self-securing flexible dams

Water-Gate is a flexible emergency flood dam that harnesses the power of floodwater to automatically fill, unfold and stabilise itself.

Water-Gate is also the latest generation of cofferdam; it simplifies river works, quickly and effectively combats pollution, and makes better use of natural water points for firefighting.

Water-Gate can be installed on any kind of terrain. It is inexpensive and protects the environment.
