Polyurethane Crack Injection in Winnipeg

Foundation Sealant Services provides polyurethane crack injection services in Winnipeg and the surrounding area, repairing basement leaks across the city.

What is polyurethane crack injection?

Polyurethane crack injection is a quick, reliable, non-invasive way of repairing cracks in concrete walls. If you have water leaks or foundation cracks in your basement, polyurethane crack injection may be for you.

Polyurethane crack injection is:

• Quick: Leaks can be fully sealed in only a few hours.
• Non-invasive: Our team only needs access to the interior side of the cracked wall. No digging.
• Inexpensive: Since no excavation is needed, crack injection is typically much cheaper than other waterproofing methods.
• Effective: Polyurethane foam can be injected through the full depth of the concrete wall, filling cracks completely from back to front.
• Durable: Polyurethane repairs typically last more than a decade.

Our Process

• Step 1: Site preparation of the wall. We install injection ports, anchor them into the crack, and seal the surface of the crack with an epoxy resin gel.
• Step 2: Injection of polyurethane foam. Injection ports allow us to fill the full depth of the crack with polyurethane, providing a durable seal.
• Step 3: Installation of steel wall-bracing (if required). This is sometimes needed for structural repairs.
• Step 4: Clean up of the work area. After we’re finished, we leave the repair site clean and tidy.

When to choose polyurethane crack injection

Most Winnipeg homes are built on clay soil, which expands and contracts more than other soil types. This constant shifting can easily lead to cracks and foundation damage, which then leak water into your basement.

Polyurethane crack injection is best for foundations with:

• Vertical cracks
• Hairline cracks
• Water leaks
• No bulging or heaving
• No horizontal or diagonal cracks

Horizontal and diagonal cracks in a basement wall usually indicate structural issues, which can’t be fixed with polyurethane alone. You may need another sealant solution, like epoxy resin injection or basement wall bracing.
