Foundation Repair
Stop the crack, stop the water, stabilize the structure.
A foundation problem only gets more expensive the longer it waits. Dollar Contracting diagnoses and repairs the full range of foundation issues Thunder Bay homes develop — cracks, water infiltration, bowing walls, settlement, and frost heave — starting with finding out why it's happening, not just patching the symptom.
For active leaks and cracks we use polyurethane and epoxy injection from the inside and, where needed, excavate and waterproof from the outside with membrane and proper weeping-tile drainage. Bowing or shifting walls get structural reinforcement — carbon-fibre straps, steel bracing, or rebuild depending on the severity.
We work on poured concrete, concrete block, and older stone foundations, and we handle the grading, downspout, and drainage corrections that caused the water problem in the first place. Every repair comes with a clear written scope so you know exactly what's being fixed and why.

Foundation Repair in Thunder Bay — FAQs
Common questions about foundation repair projects in Thunder Bay and across Northern Ontario.
Why is my foundation leaking or cracking?
Usually water and frost. Poor grading, blocked weeping tile, or downspouts dumping against the wall let water build up, then freeze-thaw pressure cracks the foundation. We fix the cause, not just the crack.
Do you waterproof from the inside or outside?
Both, depending on the problem. Interior crack injection handles many leaks quickly; persistent water or structural issues call for exterior excavation, membrane waterproofing, and drainage repair.
Can you fix a bowing basement wall?
Yes — depending on severity we reinforce with carbon-fibre straps or steel bracing, or excavate and rebuild. We assess the wall and recommend the right level of repair rather than over-selling.
