A – Leave a reasonable distance between the building to protect and the downstream edge of the dam in order to move easily and install, if necessary, a water pump.

B – Ballast the Water-Gate© leading edge uniformly in order to minimize water seepage under the dam and to ensure its ground grip.
Pay particular attention to this rule for all models without integrated weight.

C – Before placing the dam, remove all objects that could create water seepage under the ground sheet.

D – Don’t try to stop a leak downstream of the dam.
If a leak occurs under the dam, intervene at the upstream edge (ballast the leading edge, slightly bury it).
