Foundation Repair

Foundation problems are common in New Brunswick due to the province's deep frost cycles, clay-heavy soils in river valleys, and a large inventory of homes built before modern foundation standards. The frost depth in NB reaches 4 to 5 feet, and repeated freeze-thaw cycles place enormous lateral pressure on foundation walls, causing horizontal cracks, bowing, and inward displacement over decades.

Older homes in cities like Saint John, Fredericton, and Bathurst often have rubble stone foundations or thin poured concrete walls that were never designed to resist this kind of sustained pressure. Common foundation repairs include crack injection for poured concrete walls, carbon fibre strap reinforcement for bowing walls, steel beam and plate bracing for severely displaced walls, and helical pier installation for foundations experiencing settlement.

Crack injection using epoxy or polyurethane is the most affordable fix, typically $300 to $800 per crack, and works well for non-structural cracks in poured concrete. For structural issues like bowing walls or significant settlement, costs rise to $5,000 to $20,000 depending on the extent of damage and the repair method. In New Brunswick's Maritime climate, foundation repairs should always be paired with waterproofing improvements.

A repaired crack that is not properly waterproofed will allow water back in during the next heavy rain or spring thaw. Pay attention to grading around your home as well — improper drainage is a leading cause of foundation stress in NB properties. When selecting a contractor for foundation work, look for experience with NB soil conditions and older foundation types.

Structural repairs may require an engineer's assessment, and your municipality may require permits for any work affecting the structural integrity of the building. Ensure your contractor carries WorkSafeNB coverage, as foundation work involves excavation, confined spaces, and heavy lifting.
