No anti-flood system is 100% waterproof. If the flooding lasts / in case of a long distance protection, it is strongly recommended to be equipped with water pumps to prevent the accumulation of water downstream of the dam. In general, provide a pumping capacity of 10 litres / minute (infiltration, rainwater discharge networks) for each [...]
The floor space required depends on the maximum height of the barrier. Floor width (or depth) = 4 times the maximum protection height. Eg: Ref. WL2030 / Maximum protection height is = 50cm => Footprint is 2m.
The Water-Gate© materials have been tested by an independent laboratory. The Water-Gate© dams are guaranteed 12 hours to most inorganic acids, bases, hydrocarbons, polar and non-polar solvents. Please refer to the list of non-recommended chemicals in the attached data sheet.
