Cracked or Collapsed Drain Tile — Repair vs Replace in BC

Urgent

A collapsed run has zero capacity. The basement is protected only by luck until it is replaced.

Signs you have this problem

Camera footage stopping at a blockage that will not clear
Jetting that improves flow for weeks, then fails again
Sinkholes or soft depressions in the soil along the foundation
Persistent wet area on one side of the house only
A home built before the 1970s with original tile never replaced

What usually causes it

Age and material

Clay and concrete tile laid in short lengths with open joints was never a sealed system. Three to five decades of BC rain, soil movement and root pressure is its practical life.

Root pressure and soil load

Roots wedge joints apart and heavy soil, vehicles or machinery above crush pipe that has already lost its bedding.

Settlement and lost fall

As soil consolidates, sections sag and lose their slope. Water stands in the belly, silt drops out, and the pipe blocks permanently.

How it gets fixed

1. Camera inspection with locating

The footage and locate marks show exactly how many sections have failed and where, which is the entire basis for choosing repair over replacement.

2. Spot repair of isolated failures

Where the rest of the system scopes clean, only the failed run is excavated and replaced — far less cost and far less landscaping disturbance.

3. Full perimeter replacement

The foundation is excavated to the footing and new perforated PVC, filter fabric, clean drain rock, cleanouts and a proper discharge connection are installed with correct fall.

4. Waterproof while the wall is open

Membrane and dimple board on the exposed foundation costs a fraction of the excavation and is the difference between a drained wall and a dry one.

How a working drainage system protects a home

Rain runs off the roof, into the leaders, down through drain rock to the perimeter drain, then out to the storm connection or sump — keeping water off the foundation wall.

Services that solve this

Cracked / Collapsed Drain Tile — quick answer

Cracked or collapsed drain tile is footing drain pipe that has physically failed — broken, offset at the joints or crushed by soil and roots. Cleaning cannot restore it. The camera footage decides the scope: an isolated failure gets a spot repair, while original clay or concrete tile failing in several places is replaced around the full perimeter.

Cracked / Collapsed Drain Tile FAQs

How do I know if my drain tile is collapsed rather than just blocked?

A camera inspection is the only reliable way. Blocked pipe shows debris in an intact wall; collapsed pipe shows broken edges, soil intrusion, or the camera simply cannot pass. Repeated jetting that fails within weeks is a strong hint.

What does full drain tile replacement cost in Metro Vancouver?

Typically $12,000–$30,000 on a detached home, driven by perimeter length, excavation depth, machine access and how much landscaping, patio or driveway has to be removed and restored. Quotes through DRYHOMEBC are free and carry no obligation, and your request only goes to contractors already working in your city.

How long does a full perimeter replacement take?

Usually three to seven working days for a detached home, depending on access, weather and restoration. Commercial and multi-family buildings are normally phased one elevation at a time.
