We install French drains where the goal is to intercept water before it becomes a foundation problem. On homes where the pipe around the footing has already failed, a full perimeter drain replacement is the better fix, and we will tell you honestly which one your situation calls for.
French drain versus full perimeter drain replacement
These get confused a lot, so here is the plain difference. A perimeter drain is the pipe that runs around the base of your foundation footing underground; replacing it means excavating to the footing. A French drain is a separate trench, usually shallower and set out in the yard or along a slope, that catches water before it reaches the house.
If your foundation pipe has collapsed or silted up, a French drain alone will not fix a wet basement, you need the perimeter drain replaced. If your foundation drains are fine but water is pooling in the yard, running off a hill, or collecting against a wall, a French drain is often the right and more affordable answer. Many Victoria properties benefit from both working together.
Where a French drain solves the problem
French drains are the right tool in these common Victoria situations:
- Surface water pooling in the yard or along the driveway after rain
- Water running downhill toward the house on a sloped lot
- A saturated lawn that never fully dries out in winter
- Hydrostatic pressure building behind a retaining wall
- Downspout and surface runoff that needs a proper path away from the foundation
How we install it
A French drain only works if it is built right, on slope, with the correct rock and fabric, and daylighted or tied into a proper outlet. We do not just bury pipe and hope.
- Assess where water comes from and where it can safely go
- Excavate the trench on a continuous slope toward the outlet
- Line it with filter fabric to keep silt out of the pipe
- Lay perforated pipe and surround it with clean drain rock
- Connect to a safe discharge point and restore the surface
Built for Victoria clay
Clay soil is exactly why so many French drains around Greater Victoria fail early: fine clay silt migrates into the rock and clogs the pipe if the drain is not wrapped and sized correctly. We build for that, using proper filter fabric and clean rock so the drain keeps working through years of wet-coast winters.
Common questions
What is a French drain in simple terms?
It is a gravel-filled trench with a perforated pipe at the bottom. Water flows into the gravel, into the pipe, and the pipe carries it away to a safe outlet, keeping it away from your foundation or a soggy area of the yard.
Will a French drain fix my wet basement?
It depends on the cause. If water is getting in because the pipe around your foundation footing has failed, you need a perimeter drain replacement, not just a French drain. If the problem is surface or yard water, a French drain often solves it. We diagnose which one you actually need at the site visit.
How deep does a French drain need to be?
Depth depends on what you are protecting and where the water table sits. A yard drain may be fairly shallow, while one protecting a foundation runs deeper. We set the depth and slope during the assessment.
