Why do Winnipeg foundations crack so often?
Winnipeg is built on Red River Valley "gumbo" clay, one of the most expansive soils in North America. It swells when wet (spring melt, flooding) and shrinks when dry, and combined with -40°C to +35°C swings this constant movement is the leading cause of foundation cracks, settlement, and bowing walls here.
What are the signs I need foundation repair?
Sticking doors and windows, stair-step cracks in brick, drywall cracks, sloping floors, gaps between walls and ceilings, and bowing basement walls.
Are foundation cracks serious?
Hairline cracks are often cosmetic, but horizontal, widening, or stair-step cracks and any bowing signal structural movement and should be assessed promptly.
Helical piles vs underpinning, what's the difference?
Helical (screw) piles are driven below the frost line to stabilize and often lift a settled foundation, typically $300-$700 per pile. Underpinning is the broader strengthening process. Crack injection only seals leaks; it does not stop movement in gumbo clay.
Do I need a permit?
Yes, structural foundation repairs require a City of Winnipeg building permit, which your contractor handles.
