At CR Concrete Lifting, we get a lot of great questions from homeowners and property managers in Edmonton and surrounding areas. Here are the most common questions — and our expert answers — about foam jacking, sunken driveways, trip hazards, and more.
Concrete sinks when the soil underneath shifts, washes out, or compresses over time. This is common in Alberta due to freeze-thaw cycles, water drainage issues, or poor soil compaction during construction.
We drill small holes in the slab and inject a structural expanding polyurethane foam underneath. The foam fills voids and gently lifts the slab back to its original position, then hardens to provide long-term stability.
Yes — polyurethane foam is lighter, stronger, faster to cure, and less invasive than traditional mudjacking. It requires smaller holes and doesn’t add heavy material that can cause future settling.
Most residential concrete lifting jobs (like sidewalks, patios, or driveways) take 2 to 6 hours. You can walk or drive on the area the same day in most cases.
Yes, it’s a long-term solution. The foam is water-resistant, won’t shrink, and stays in place. However, future soil movement or water issues may cause new settlement nearby, so we also help you identify drainage risks.
We service Edmonton, Sherwood Park, St. Albert, Leduc, Spruce Grove, Fort Saskatchewan, and surrounding communities. We also do larger commercial or industrial projects across Alberta.
It depends on the scope, but most residential jobs fall between $850 and $6000. We offer free estimates and early-season or referral promotions.
Yes — we often lift sunken garage pads, basement floors, and commercial warehouse slabs. These require specialized equipment and access but are very doable with foam jacking.
We offer crack sealing and joint caulking as part of our services to help protect your lifted slab from water infiltration and future movement.
