Wet Basement Repair — Metro Vancouver & Fraser Valley

Common causes in BC

Failed or silted drain tile, downspouts discharging beside the foundation, negative grading, high winter water table, and cracked or porous foundation walls.

Interior vs exterior solutions

Interior drainage systems with a sump are faster and cheaper; exterior excavation with membrane and new drain tile addresses the cause and protects the structure.

Moisture control

Vapour barriers, dehumidification and crawl space encapsulation are usually part of a complete wet basement repair.

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.

Wet Basement Repair — quick answer

A wet basement is a symptom, not a diagnosis. The fix depends on whether water is entering through the wall, up through the slab, from a failed perimeter drain, or from surface water pooling against the house.
