French Drain in Blainville

Our French drain services in Blainville

New French drain installation in Blainville covers new builds and full replacement of drains that have reached end-of-life. The crew excavates the foundation perimeter down to the footing, lays a bed of clean sized gravel, sets the perforated pipe with a continuous slope of at least 1% toward the outlet, wraps the assembly in geotextile, and connects either to an interior sump pit with a submersible pump, or directly to the municipal storm sewer where the city allows it. All work is done to the Quebec Construction Code.

High-pressure cleaning restores flow on a drain clogged by sediment, fine roots from mature trees, or iron ochre. Our hydroflush equipment pushes water at up to 4,000 PSI through the pipe via existing cleanout risers or through access we create on the spot. In the older residential neighbourhoods of Blainville, where the trees are mature and the drains older, a preventive flush every 5 to 8 years prevents backups and extends the useful life of the system.

Camera inspection rides along with almost every job we do. Before the work, it confirms the exact cause of the problem, whether a collapsed drain, a root that punched through the pipe, an iron-ochre deposit, or simple sediment. After the work, it confirms the drain is clean and functional along its full length. You receive the video and the written report for your records or for an eventual insurance claim.

Iron ochre is not systematic in Blainville, but it shows up in certain sectors where the water table is more active. Our removal protocol combines high-pressure hydroflush, suitable chemical treatment, and installation of extra cleanout risers to make future maintenance straightforward. On new installs in at-risk zones, we specify BMT corrugated pipe rather than standard perforated PVC, which flushes out more easily and limits the build-up of iron biofilms.
