French crack and drain repair in Buckingham, Gatineau, QC

Refurbishment of a section of the foundation of a house located in Gatineau in the Buckinghamarea. Initially, there was talk of a crack repair and waterproofing of the damaged part. After the excavation, we discovered a big installation error at the existing French drain. This is more specifically the location of the exit point of the drainage system.

Crack

The crack was passive in nature. A high-pressure clean was done after the crack and two other parts of the foundation were deed that were damaged. The whole thing was repaired with concrete. For the crack mechanical inkings have been installed.

French Drain and Catchment Basin

The foundation was already protected by a drainage system. However, this one is not up to standard. The contractor who installed the system relied on the top point of the sole to determine the level of the drain. Because the height of the sole varies, the output to the catchment basin was higher than part of the drainage system (see image with the arrows). This is unacceptable since the water can never be effectively discharged through the French drain.

This exit was blocked with concrete and redone to the lowest level reached by the drainage system.
