Solve pooling water and slope issues with practical drainage systems tailored to your property.
Poor drainage is one of the most common and damaging issues for Montreal properties, especially given our heavy spring snowmelt and intense summer rainstorms. Our drainage solutions begin with a thorough assessment of water flow patterns, soil composition, and grading around your foundation and yard. We identify low spots where water pools, areas where surface runoff erodes garden beds, and foundation walls at risk of moisture infiltration. Solutions range from simple regrading and swale creation to full French drain systems with perforated pipe bedded in clear stone and wrapped in filter fabric. For properties with severe clay soil that resists natural percolation, we install catch basins connected to solid pipe that directs water to the street or a dry well. We also build channel drains along driveways and patio edges where surface water concentrates. Every installation follows the slope requirements set by Quebec building standards -- a minimum two percent grade away from foundations for the first six feet. Where space is limited, we use compact trench drains or permeable paver systems that allow water to infiltrate on-site rather than overwhelming municipal storm drains. All our drainage pipe is rigid PVC or corrugated HDPE rated for below-grade burial in cold climates, and we backfill with washed three-quarter-inch clear stone for maximum flow capacity.

FAQ for this service
How do I know if my yard has a drainage problem?
Signs include standing water more than 24 hours after rain, soggy patches in the lawn, water stains or dampness on basement walls, erosion channels in garden beds, and ice buildup near walkways in winter. If you notice any of these, a professional assessment can identify the root cause and the most cost-effective fix.
What is a French drain and when is it needed?
A French drain is a trench filled with clear stone and a perforated pipe that collects groundwater and directs it away from problem areas. It is the go-to solution when subsurface water is saturating your yard or pressuring your foundation walls. We install them along foundation perimeters, at the base of slopes, and across low-lying lawn areas.
Can drainage work be done without tearing up the entire yard?
In many cases, yes. Targeted solutions like localized regrading, catch basin installation, or a single French drain run can resolve the issue with minimal disruption. We restore any disturbed lawn areas with fresh sod and match existing garden bed materials so the repair blends in within a few weeks.
