French drain in Mascouche

Our French drain services in Mascouche

For a new installation in Mascouche, we lay a Code-compliant drain: perforated pipe on a bed of sized clean gravel, continuous slope of at least 1% toward the outlet, geotextile membrane over the top to prevent clay particles from migrating into the line. In clay soil, the quality of the geotextile and the care put into the gravel bed make a real difference on drain life — this is where penny-pinching costs the most in the long run.

For an existing drain that is starting to slow, high-pressure cleaning is the go-to intervention. A rotating nozzle is fed through the cleanout risers and sprays water at several thousand psi, lifting fine sediment, roots and iron-ochre deposits. On older drains in Mascouche's established sectors, we always match the pressure to the pipe material so we do not damage a line that is already fragile from soil movement.

A camera inspection accompanies all our jobs. Before work, it pinpoints the blockage and identifies its nature — sediment, roots, iron ochre, crushed or sagging pipe. After work, it confirms the drain is clear. You receive the video and a written report. For Mascouche homes without cleanout risers, we often suggest installing four risers at the corners of the footing during the visit, which makes all future maintenance simpler.

Iron ochre is present in several sectors around Mascouche. Mechanical flushing alone is not enough: we add a sterilisation step for the iron-loving bacteria (Gallionella, Leptothrix) that cause the orange deposit, otherwise the ochre returns quickly. In advanced cases, adding a sump-pump drain or an interior cuvelage may be required to manage the problem for the long term, and we walk you through the options in plain language with a written estimate before any commitment. The right approach depends on how much iron ochre is in the soil, how much access the property allows, and what you are willing to invest now versus over the next decade of ownership.
