The walls of concrete, formwork blocks are not sufficient to guarantee the absence of penetration or leakage of water.
CONSTRAINTS

- in case of water supply, enlarge the hole infiltration to a minimum area of 3 x 3 cm
- then plug the hole with the mortar clogging weber.dry stop
- to achieve continuity in the waterproofing layer, make a groove in all the corners, using:
- to concrete: weber.rep fast or weber.rep area
- blocks of formwork: weber.rep fast or coated weber.dry
