French drain installation
The project consisted of installing a french drain on the 3 facades of the building constructed in the 1930s, in order to protect the foundations against humidity and allow better stormwater drainage.
The general contractor in charge of the project started with the excavation work up to the footings, all along with the building. Then, the foundation walls were cleaned and dried before repairing the concrete cracks. Then, the contractor proceeded with the waterproofing of the foundation walls with the installation of the Delta MS waterproof membrane. The french drain was subsequently installed along with the footings: it is perforated conduct, under a stone backfill, to allow the collection of water. It is connected to a new custom-built catch basin in the basement of the building.
The contractor also installed access and maintenance chimneys for the drain from the surface. The work was finished with the soil backfilling and the installation of new window wells.
