Basement Floor Crack Repair
Servicing Calgary and Surrounding Areas
Cracks in your basement floor are more than just a cosmetic issue - they can be a sign of underlying foundation problems, water seepage, or soil settlement. Left untreated, they can allow moisture to enter, leading to potential mold growth and further structural damage.
Our Basement Floor Crack Repair Solutions: Polyurethane Injection
At CrackPros, we specialize in repairing basement floor cracks using advanced sealing techniques that prevent moisture intrusion and reinforce the floor’s integrity. When water seeps through cracks in your floor, we begin by installing a perimeter drain system and a direct drainage channel to redirect water to your sump pump. To ensure a lasting solution, we backfill the crack with stone and cover it with fresh concrete to prevent future leaks. Our advanced polyurethane injection method expands to fill the crack, creating a flexible, waterproof barrier that adapts to any minor foundation movement, preventing re-cracking and providing long-term protection.
Causes of Basement Floor Cracks

Hydrostatic Pressure
Excess groundwater creates pressure beneath the slab, leading to cracks and potential water intrusion.

Soil Movement Beneath the Slab
Shifting or settling soil causes uneven stress on the foundation, resulting in floor cracks over time.
Natural Concrete Shrinkage
As concrete cures, it naturally shrinks and may form small cracks on the basement floor.
Signs You Need Professional Help:
Recognizing Red Flags Early
Even small foundation cracks can lead to bigger problems if left untreated. Spotting the early signs of damage can help you avoid costly repairs down the road. Your home’s foundation is what everything else rests on - keeping it strong means keeping your home safe. If you notice any of the signs below, it’s a good idea to have them looked at sooner rather than later. We're here to help with honest advice and reliable repairs you can count on.
Cracked Basement Floor Slab: Hairline or widening cracks in the basement floor can signal concrete shrinkage, pressure from beneath, or shifting soil. Even small cracks can worsen over time and let moisture in.
Water Seepage or Damp Spots: Is water pooling on the floor or seeping up through cracks? This is a strong sign of hydrostatic pressure or drainage issues beneath the slab.
Musty Odours or Humidity: A persistent damp, earthy smell in the basement is often due to moisture entering through floor cracks - creating the perfect environment for mold and mildew.
Efflorescence (White Chalky Residue): White, powdery deposits on your basement floor are signs of water passing through the concrete and leaving mineral traces behind - a subtle but clear moisture red flag.
Increased Radon Levels: Cracks in the slab can allow radon gas to enter your home from the soil below. If you’ve tested for radon and the levels are high, a cracked floor could be the culprit.
Cold or Uneven Flooring: Noticeably cold areas or uneven sections on your basement floor may be a sign of slab movement or shifting support underneath.
