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, streets, railway tracks, building outlines, heightening dikes, cofferdams in the rivers, etc.) very quickly.
All paths, even complex, are possible.
