Wet Basement Repair in White Rock, BC

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. Steep bluffs and marine soils above Semiahmoo Bay mean White Rock drainage work focuses on dewatering, sump systems and foundation protection on sloped lots.

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.
