Common Water Issue in BC
Foundation Crack with Active Water Entry
A visible crack in the foundation wall that weeps, seeps, or streams water during wet weather requires immediate attention. The water entry may be accompanied by efflorescence staining, and the crack may widen over time if hydrostatic pressure continues. In BC's clay soil regions, foundation cracks are a common and recurring problem.
Possible Causes
- •Hydrostatic pressure from saturated soil pushing water through the crack
- •Expansive clay soil swelling and contracting with moisture changes
- •Clogged or failed perimeter drainage system increasing water pressure
- •Poor surface drainage concentrating water near the foundation
- •Tree root pressure or soil settlement causing crack widening
Recommended Steps
- 1Direct water away from the foundation — clear gutters and extend downspouts
- 2Temporarily seal the crack with hydraulic cement if water entry is active
- 3Do not apply interior waterproofing paint — it will peel and trap moisture
- 4Schedule a foundation inspection to determine if interior epoxy injection or exterior excavation is needed
