INFORMATION
The drainage allows the continuous evacuation of water, at the foot of the pool and, therefore limits the rising of water by capillary
attraction towards the upper part of the works, where air and soil interact to produce fungi or rot (lower diagram)
The absence of draining causes water to ascend by capillary action that can be important and permanent, which favours the
attacks of air / water interaction (lower diagram).
In the case of an attack and if no draining exists, the guarantee cannot be applied to the deterioration.
