Foundation Waterproofing

Edmonton’s Interior Foundation Crack Repair Specialists

At CrackFix, we provide quality, long-lasting foundation crack repair from the inside. This is a clean, much more cost-effective solution with no exterior digging required. We only utilize high-quality commercial-grade Polyurethane and Epoxy resin to seal cracks deep within the concrete foundation to prevent water intrusion and further structural damage. 

Our company’s goal is to ensure we provide dry basements, Solid foundations, Peace of mind, and build a strong relationship with our clients, as we believe quality work and customer service are equally important. 

Why Choose Interior Foundation Crack Injection?

Our interior injection method is designed to fix foundation cracks permanently, without disturbing landscaping, driveways, or patios. This is not only more cost-effective than exterior repairs, but it will be a permanent repair as the commercial resins we use do not break down or change over time. Here’s how our unique process works:

1. We identify and clean the crack on the interior foundation wall.
2. We drill injection ports directly into the concrete along the crack path.
3. We apply epoxy or polyurethane resin, depending on the type of crack, under pressure to fill the full depth of the crack, sealing the entire crack from the visible surface to the outside, plus adding some resin to the outside for extra protection. 
4. The crack is sealed and waterproofed to prevent future leaks, mold, or structural weakening.

This method is less expensive, more discreet than exterior excavation, and generally less time-consuming. It’s ideal for basements, crawl spaces, underground parkades, and even in-ground cisterns where access is limited from the outside, or it will be very messy and expensive from the outside. We do not require access to the outside of cracks below grade, so this eliminates any need to damage landscaping, concrete walkways, or driveways.

Common Signs of Foundation Cracks

Watch for early warning signs like:

• Cracks that are visible on the outside of the home 
• Hairline, vertical, diagonal, or horizontal cracks in basement walls inside
• Water seepage during rain or snowmelt
• Efflorescence (white powder) or stains on concrete walls
• Damp or musty basement smell
• Bowing or shifting of concrete
• Mold or mildew around the base of walls
• Discoloration or warping of baseboards in the finished basement.

These symptoms could indicate underlying foundation issues, and postponing the repair can lead to higher repair costs as the cracks generally become larger if not repaired due to the water infiltration and freeze-thaw cycle.

FAQs

Q: Will you need access to the crack from the outside?

A: NO. Our repair process does not involve any digging or damage to the exterior of the home. We repair directly on the exposed foundation from the inside.

Q: What’s the difference between epoxy and polyurethane?

A: Epoxy is stronger and ideal for structural cracks. Polyurethane expands and seals water leaks. We choose the right product based on your specific crack type. Both resins have specific applications, and we can professionally advise on the type of resin based on the foundation crack.

Q: Is this method permanent?

A: Yes, when done professionally. Almost all of the jobs we do come with a lifetime warranty. Our materials and process are designed to stop leaks and stabilize cracks long-term, backed by a warranty. If the issue falls in the 1% that we can’t provide a lifetime warranty, we will honestly  and clearly discuss the warranty details with our clients for their peace of mind.
