FOUNDATION DEFENSE
Why Choose Concrete Solutions for Waterproofing in Thunder Bay
A wet, leaking basement in Thunder Bay leads to foundation concrete degradation, mold growth, and ruined living space. With our region's high seasonal water tables, heavy clay soils, and massive spring thaw runoff, foundation walls endure intense hydrostatic pressure. At Concrete Solutions, we diagnose and permanently eliminate foundation water leaks from the outside in.
We believe in permanent multi-layer exterior defenses. We excavate down to the footings, thoroughly wash and repair foundation cracks with hydraulic cement, apply seamless elastomeric rubber membranes, install Delta-MS dimple drainage boards, and replace crushed or clogged weeping tile with modern filter-fabric wrapped drainage pipe.
What Sets Us Apart
- Multi-layer protection: rubberized membrane + Delta-MS board
- Full perimeter weeping tile replacement with clear stone backfill
- Hydraulic cement crack repair & pressure polyurethane injection
- Sump pump installation, check valves & window well drainage
HOW WE WORK
Our Waterproofing Execution Workflow
A comprehensive exterior remediation protocol designed to keep foundations dry for decades.
01
Perimeter Excavation
We excavate a safe trench around the foundation down to the footing level, exposing the full concrete wall.
02
Power Washing & Crack Repair
The wall is high-pressure washed clean, all structural cracks are chiseled out, and sealed with hydraulic cement.
03
Membrane & Delta-MS Board
We roll an elastomeric rubber membrane across the wall and mechanically fasten high-density polyethylene Delta-MS dimple board.
04
Weeping Tile & Clear Stone
New perforated drainage tile is installed in a washed 3/4" clear stone envelope before clean backfilling and positive slope grading.

COMMON QUESTIONS
Frequently Asked Questions
Important facts about basement leaks, weeping tile systems, crack injections, and warranties in Thunder Bay.
Standard damp-proofing (traditional sprayed black tar) merely retards moisture vapor and becomes brittle over time. True structural waterproofing incorporates thick elastomeric rubberized membranes and protective dimple drainage boards (Delta-MS) that actively bridge settling cracks and resist standing hydrostatic water pressure.
Exterior waterproofing is the proven industry gold standard because it prevents groundwater from ever entering and saturating your concrete walls. Interior drainage systems manage water after it enters, which is useful when property boundaries or tight zero-lot lines prevent exterior excavation.
We repair wall cracks from the exterior by grinding the crack, packing it with high-strength hydraulic cement, and covering it with rubberized membrane and dimple board. For interior treatments, we use high-pressure polyurethane foam injections that expand deep into the crack to form a flexible, watertight seal.
A professionally installed exterior system featuring elastomeric rubber membranes, Delta-MS air-gap dimple boards, and 3/4" clear aggregate wrapped weeping tiles lasts 30 to 50+ years, permanently protecting your home from water ingress.
