French drain in Joliette

Our French drain services in Joliette

For a new build or a full replacement in Joliette, we install a Code-compliant drain: perforated pipe on a bed of sized clean gravel, continuous slope of at least 1%, geotextile membrane to prevent fine particles from migrating into the line. On the old downtown homes, excavation often demands particular care because of mature landscaping and the proximity of neighbouring buildings.

High-pressure cleaning remains the most frequent intervention on existing Joliette drains. We feed a rotating nozzle through the cleanout risers and spray water at several thousand psi to lift sediment, fine roots and iron-ochre deposits. Pressure and nozzle are matched to the pipe material so we do not damage a line that is already fragile — especially important on the concrete or clay tile pipes still in service in many century-old homes.

Some sectors around Joliette show a high concentration of iron ochre in the soil. Mechanical flushing alone is not enough: we systematically add a sterilisation step targeting the bacteria (Gallionella, Leptothrix) responsible for the orange deposit, otherwise the ochre returns quickly. In advanced cases, a sump-pump drain or interior cuvelage may be required to manage the problem for the long term, and we walk you through the options in plain language before any commitment.

A camera inspection accompanies every job. Before work it pinpoints the blockage and identifies its nature — sediment, roots, iron ochre, crushed or sagging pipe. After work it confirms the line is clear. You receive the video and a written report logging the drain's condition and anything to keep an eye on over the next few years. For Joliette homes without cleanout risers, we offer to install four risers at the corners of the footing during the visit, which makes future cleanings dramatically simpler and cheaper, and means no further excavation will be needed to confirm the drain's condition five or ten years down the road.
