Basement Crack Repair Toronto | Dryshield Experts

Our basement crack repair process

Basement crack repair isn’t just another household chore—it’s a smart move to stop water damage, protect structural integrity, and keep property values climbing across Canada’s wet seasons. Curious how we tackle every crack with precision? Check out our step-by-step process below to see exactly how we get the job done right.

01. Inspection: We examine basement walls, floors, windows, and doors, mapping hairline cracks, wide cracks, and horizontal cracks. Moisture meters and flashlights reveal hidden basement leaks, loose concrete, and early signs of structural problems.

02. Surface Prepration: Our technicians wire-brush debris and dust, vacuum concrete surfaces, and bevel small cracks for better bonding. Clean substrates ensure that concrete crack filler, hydraulic cement, or epoxy adheres to the foundation wall.

03. Port Placement: Injection ports are glued with crack sealer along the full crack length. Proper spacing lets low-pressure epoxy injection travel deep, fill voids, and seal basement leaks without damaging finished areas.

04. Exterior Seal: A quick-cure surface epoxy forms a gasket that contains injection pressure. This barrier stops resin from escaping, protects adjacent concrete walls, and prevents radon gas and water from re-entering the crack.

05. Crack Injection: We inject expanding resin from the bottom to the top using a professional caulking gun. The epoxy fills, bonds, and restores structural integrity, creating a long-lasting repair inside concrete structures and foundations.

06. Carbon Reinforcement: Carbon-fibre staples or straps lock both sides together for structural cracks. Combined with epoxy, this upgrade resists soil pressure, prevents more cracks, and strengthens the basement foundation for decades.

07. Finishing: Ports are clipped off, and hydraulic mortar feathers the edges for a smooth surface. We tint the patch so the repaired concrete matches the surrounding wall, leaving no rough spots to catch dust or moisture.

08. Quality Check: After curing, we pressure-spray water to verify a perfect seal. Technicians re-inspect adjacent areas, ensuring no new wall cracks, basement leaks, or surface bulges threaten future structural integrity.

09. Cleanup & Report: Worksite is swept, vacuumed, and debris removed. Homeowners receive photos, maintenance tips, and a transferable warranty covering each injected crack, crack repair kit materials, and labour across Canadian climates.

Signs that you need basement foundation crack repair

Water stains along concrete walls after storms indicate basement leaks that demand crack repair.
Musty odours and damp floors show moisture seeping through foundation cracks, risking mould.
Efflorescence, a white powder on concrete surfaces, signals ongoing water damage and mineral wash-out.
Horizontal cracks as wide as a toonie reveal exterior soil pressure compromising structural integrity.
Hairline cracks lengthening upward beside basement windows suggest settling that widens with freeze–thaw cycles.
Doors or windows suddenly sticking hint that the foundation wall has shifted due to unresolved structural problems.
Loose concrete or flaking paint around wall cracks points to prolonged moisture and failing surface bonds.
Visible daylight or drafts through any crack confirm significant movement requiring immediate basement crack repair.
Uneven basement floor slabs paired with vertical cracks mean soil voids and need professional epoxy crack injection before costly heave.

Frequently Asked Questions

Why do cracks appear in basement walls or floors?

Cracks can develop due to natural settling, temperature changes, soil pressure, or water buildup. In Canada, the expansion and contraction of frozen ground is a major cause of basement cracks.

Is a cracked basement wall a serious problem?

It depends on the crack. Hairline cracks are usually not serious, but wide, deep, or leaking cracks can cause water damage, mold growth, and structural issues. It is best to have a professional inspect any significant cracks.

Can I repair basement cracks myself?

Small surface cracks can be sealed with DIY products, but leaking or deep cracks require professional repair. Experts use injection methods that seal the crack from the inside and prevent further problems.

How are basement cracks repaired?

Most basement cracks are repaired by injecting polyurethane or epoxy into the crack. Polyurethane is the best option for stopping water seepage because it expands and seals the crack completely. Epoxy is mainly used when structural strength needs to be restored. These materials prevent leaks and protect the basement even if the concrete moves slightly.

How much does it cost to repair a basement crack in Canada?

Repair costs generally range from $500 to $1,500 per crack, depending on size and severity. Cracks that leak or require excavation may cost more. A professional inspection provides an accurate estimate.

Can water leak through small cracks in the basement?

Yes, even small or thin cracks can allow water to seep in, especially during heavy rain or snowmelt. Early sealing of cracks is important to avoid moisture problems and mold growth.

How long does a basement crack repair last?

When repaired professionally with quality materials, basement crack repairs can last many years. Polyurethane is flexible and durable, making it well-suited for Canadian homes where soil shifts and moves.
