Mudjacking uses a heavy cement mixture (about 100 lb/ft³) to lift the slab. Polyurethane injection uses a lightweight expanding foam (about 4 lb/ft³) that hardens within minutes. The foam is hydrophobic and withstands Quebec’s freeze-thaw cycles. It requires smaller injection holes (less than 1 inch) and offers greater lifting precision. At DuraLift, we exclusively use high-density polyurethane injection.
Leveling by injection costs between 50% and 70% less than a full replacement. A replacement involves demolition, hauling, soil preparation, and pouring new concrete, which often takes several days. Leveling is completed in a few hours, with no demolition required. Every project is different, contact us for a free on-site quote.
The most common causes in Quebec are clay soil that expands and contracts with moisture, freeze-thaw cycles, poorly compacted backfill from construction, and erosion caused by poor surface water management. Water seeping under the slab creates voids that grow over time. The longer you wait, the worse the problem gets.
Our main season runs from spring to fall, since the ground needs to be accessible for the work. When the soil is frozen deep down, outdoor work becomes more difficult. Indoor projects (garage floors, basement slabs, commercial floors), however, can often be done year-round. Contact us early in the spring to reserve your spot, demand is high between May and October.
Concrete settling is generally considered normal wear and tear or soil movement, which is usually not covered by homeowner’s insurance in Quebec. Certain specific situations (such as a broken underground water pipe) may sometimes be an exception. Check with your insurer, our detailed quote can serve as documentation if you file a claim.
No, we only level poured concrete slabs.
Concrete leveling is a process that involves lifting sunken or uneven concrete surfaces by injecting a foam material under the slab. This foam expands and hardens like concrete, stabilizing the concrete and bringing it back to its original level.
Concrete leveling is often more cost-effective and faster than complete slab replacement. It also causes less disruption to your property as it doesn’t require demolition.
The process typically takes a few hours to a day, depending on the size and complexity of the job. Once completed, the area is safe to walk on, and vehicles can drive on it after about 15 minutes.
No, our process is clean. We use minimal equipment and only create small, discreet holes that we fill with hydraulic cement where we inject the foam. There’s no need for large machines or causing a big mess.
We use high-quality materials like DURA foam, designed to provide long-lasting results. However, some conditions (such as extreme soil movements) can affect stability over time.
Concrete leveling is a permanent solution for most situations, but the exact duration depends on environmental factors such as soil movements, water exposure, and heavy vehicle traffic. With proper maintenance, we guarantee our products for 12 years*. Contact us for all the details.
Yes, concrete leveling can be applied to various surfaces, including driveways, sidewalks, patios, providing stability. However, foundations and footings are case-by-case.
Yes, the process is safe for your property. We ensure that the leveling is done accurately, without risk to surrounding areas. The foam we use is non-toxic and environmentally friendly.
Yes, it’s preferable to adjust the slabs to facilitate the adjustment of the liner edge. The pool installer will have perfect angles for a better finish and won’t have to return to make adjustments.
When properly installed, the pipes won’t be affected because we only drill into the slab. The pipes are usually buried under the backfill.
The cost varies depending on the size of the area, the extent of damage, and the materials used. We offer free quotes so you have a clear idea of the price before starting the work.
