Is the Water-Gate barrier watertight?
Watertightness increases with the flood height and the pressure exerted by the liquid on the floor fabric.
The leakage rate is less than 1.06 Gallon (U.S) per min. and per lenear meter on smooth floor (concrete type).
If this leakage rate is considered to be too great, it is possible to reduce it considerably by spreading under the leading edge a seal of mastic or silicone cartridge type, or natural products of molasses type. Viscous material in order to increase the adherence of the barrier on the ground and fill the micro cracks.
Watertighness depends on the soil condition (the smoother the soil the better the watertighness) and on his draining effect (important for the long-term floods).
Leakage rate generally determined by rough floor type, without additional leakage measurement.
Concrete or recent coating < coated
Concrete damaged < pavers < grass < soil < sand < gravels < stones < 2.64 Gallon (U.S) per min
