About Perimeter Drainage Systems in Vancouver

Water management is the single most important factor in foundation health in Metro Vancouver. The Fraser Valley and Lower Mainland receive precipitation year-round, with prolonged saturating events from October through April. Without functional perimeter drainage — weeping tile — that water builds up against the foundation, creating hydrostatic pressure that forces moisture through cracks and cold joints, and exerts lateral loads that bow walls inward. Most homes built before 1990 in Metro Vancouver have clay tile or early perforated plastic weeping tile that has collapsed, silted in, or simply reached end of life. Replacing it is the most impactful single investment you can make in your foundation's long-term health. Vancouver Foundation Repair Co brings the right equipment and the right method to every job.

Our Perimeter Drainage Systems Process

Camera Inspection

We camera-inspect existing weeping tile to assess condition before recommending replacement versus repair. Failed sections are precisely located to target excavation.

Excavation

Trenches are excavated to the footing using mini-excavator. Existing failed weeping tile is removed. We note and protect all service utilities encountered.

New Drain Installation

Clean-sock wrapped 4" perforated pipe is installed on a 6" gravel bed at the footing level, sloped at minimum 1% grade to daylight or a sump. Inspection ports installed at every change in direction.

Backfill & Restoration

Trench is backfilled with free-draining gravel to within 12" of grade, then capped with native soil and restored. Sod, plants, and hardscape are replaced matching pre-dig conditions.

Perimeter Drainage Systems FAQ

How do I know if my weeping tile has failed?

Signs include persistent basement moisture despite no visible cracks, efflorescence on the lower portion of foundation walls, and wet soil at the base of the foundation wall. A camera inspection through an existing cleanout (or a small test pit) gives definitive confirmation.

Does interior drainage replace perimeter drainage?

They serve different functions. Interior drainage manages water that has already entered the building envelope. Perimeter drainage prevents water from reaching the foundation in the first place. Exterior perimeter drainage is more effective but more disruptive; interior systems are less invasive but don't reduce the hydraulic load on the wall.

Can you install weeping tile without disturbing my landscaping?

Full perimeter weeping tile replacement requires excavation and will disturb landscaping, concrete flatwork, and fencing in the trench path. We photograph everything before work starts and restore the trench path to original condition.
