Complete guide to professional drainage services available through our network of licensed Canadian contractors.
A perimeter drain (also known as a weeping tile or footing drain) is a system of perforated pipes installed around the base of your home's foundation. Its purpose is to collect groundwater and redirect it away from the foundation to prevent water infiltration, hydrostatic pressure buildup, and structural damage.
Over time — especially in homes built before the 1990s — original clay or concrete drain tiles crack, collapse, and become clogged with sediment, roots, and mineral deposits. When this happens, water has nowhere to go and begins pressing against your foundation walls, leading to basement flooding, mould growth, and foundation failure.
Perimeter drain replacement in Canada typically ranges from $8,000 to $25,000 CAD depending on property size, accessibility, depth of excavation, soil conditions, and regional labour rates. Always get at least three written quotes from licensed contractors.
These terms are often used interchangeably, but there are important distinctions:
| Feature | Perimeter Drain | Drain Tile |
|---|---|---|
| Definition | The complete drainage system around a foundation | The individual pipe component within the system |
| Materials | Pipe + gravel + filter fabric + membrane | Originally clay tiles; now PVC Big-O pipe |
| Location | Foundation perimeter at footing level | Can be interior or exterior |
| Historical | Modern term for the complete system | Term from when actual clay tiles were used |
| Common usage | Western Canada (BC, AB) | Eastern Canada (ON, QC) and older references |
When a contractor says "drain tile replacement," they typically mean replacing the perforated pipe within your perimeter drain system. When they say "perimeter drain replacement," they mean replacing the entire system including excavation, pipe, gravel, fabric, and membrane.
A CCTV camera inspection involves feeding a high-definition waterproof camera through your drainage system to assess pipe condition without excavation. This technology saves homeowners thousands of dollars by accurately diagnosing problems before committing to expensive repairs.
Professional drain cleaning removes blockages, buildup, and root intrusion from your drainage system. Two primary methods are used:
A rotating metal cable with a cutting head is fed through the pipe to break up blockages. Effective for simple clogs and soft blockages. Lower cost, but doesn't remove buildup from pipe walls.
High-pressure water (up to 4,000 PSI) is blasted through the pipe, scouring the interior walls and flushing all debris out of the system. More thorough than snaking, removes grease, scale, roots, and sediment completely. Recommended for older systems with decades of buildup.
French drains are shallow trench drains designed to manage surface water and subsurface water in yards, driveways, and along retaining walls. Unlike perimeter drains (which protect foundations), French drains solve specific water management problems in your landscape.
A sump pump collects water from your perimeter drain system and pumps it away from your foundation to the municipal storm system or a discharge point. Essential for homes where gravity drainage isn't possible.
Foundation waterproofing involves applying a moisture barrier to the exterior of your foundation walls during perimeter drain replacement. This provides a secondary line of defence against water infiltration and is recommended any time the foundation is exposed for drainage work.
