It depends on the chosen model. We sell barriers from 15cm up to 2 meters high. Please refer to the number indicated on each Water-Gate© dam. The first 2 numbers correspond to the maximum height of retention, in inches. For instance: WL-20 is 20 inches high or 50cm. Thanks to edge [...]

The Water-Gate© dams are produced in individual lengths ranging from 4.6m to 15,20m. All dams can be linked together regardless of size or category , by Velcro fasteners. It is possible to indefinitely extend the length of protection without loss of efficiency. Water-Gate© efficiently delivers hundreds of metres of protection (docks, [...]

There is no minimum height. The Water-Gate© barrier will work from the first centimeter of water. It is the water pressure which opens and deploys the dam and not the flow or flood speed.

Water-Gate© products are all-terrain. They embrace all obstacles, rocks, rails, walls … Excellent grip on most types of soil, grass, lawn, paving stones ... even on ice!

The Water-Gate© dams are particularly suitable for flash floods. The leading edge of the dam, facing flooding, is weighted . The flow rushes into the bottom of the dam literally "nailed to the floor". During our demonstrations we show how the dam can resist the pressure of a fire hose. Water-Gate© [...]

Yes it is quite possible. The water level is not a problem. A strong current may however make installation difficult. The in-river installation manœuvre should then be respected.

Indeed, any flood carries a greater or lesser amount of sediment. Even in large quantities mud should not alter the stability and effectiveness of the dam.

Once installed, the Water-Gate dam is capable of resisting all types of currents, strong winds and waves. We will advise you of the installation precautions that you should follow according to the prevailing weather conditions. The item's resistance to strong (force 12) winds was tested at the CSTB in Nantes [...]

Flexible and resistant, Watergate is incredibly resilient. It absorbs impact energy and resumes its original shape. Resistance to impact was tested by the US Army. See the video.

The seal increases with the height of flooding and the pressure of the liquid on the ground sheet. The leakage rate is less than 4 L / min per linear metre of smooth ground (concrete type). If this leakage rate is deemed too high it is possible to significantly reduce it. [...]
