Concrete lifting raises a sunken slab back to its original level without removing it. Small ports are drilled through the concrete, expanding polyurethane foam is injected underneath, and the slab rises in controlled stages while we watch it against a laser level. The ports are patched, the joints are resealed, and the surface goes straight back into use. The insight that makes this work is simple: in most cases the concrete is fine. It sank because the ground under it moved, not because the slab failed. Toronto clay shrinks as it dries and leaves voids. Trench backfill over a service line settles. Water from a downspout washes fines out from underneath. Engineered fill in newer subdivisions keeps consolidating for years. In every one of those situations you have perfectly good concrete sitting on nothing. Replacing that concrete costs $10 to $16 per square foot, takes days, and involves demolition, disposal, curing and disruption. Lifting it costs $6 to $12 per square foot and is done in hours. We use polyurethane foam rather than traditional mudjacking for most GTA work. Mudjacking pumps a heavy cement slurry into the void, which is effective but adds considerable weight to a subgrade that has already proven it cannot carry what is on it. Foam weighs a small fraction of that, expands to fill irregular voids completely, cures in minutes, and needs ports about the diameter of a pen rather than the large holes slurry requires. ### What’s Included - Void mapping and cause diagnosis - Port drilling on an engineered pattern - Polyurethane foam injection, or mudjacking where preferred - Laser-level monitoring throughout the lift - Controlled staged raising to avoid over-lifting - Sub-base stabilisation where soils are weak - Port patching flush with the surface - Joint cleaning and resealing - Post-lift drainage check ## Common Problems We Solve ### Sunken Driveways at the Garage or Sidewalk The two places driveways drop most, because both are transitions where compaction is hardest to achieve. Lifting restores grade and stops meltwater running toward the garage or the house. ### Trip Hazards on Walkways A walkway panel that has dropped an inch is a genuine liability. Lifting it is faster and cheaper than replacement, and does not leave a new panel that does not match the weathered ones beside it. ### Settled Garage and Basement Floors Interior slabs are the strongest case for lifting, because the alternative is breaking out and repouring inside a finished building. Higher-density foam handles the load. ### Pool Deck and Patio Settlement Backfill around a pool is rarely compacted as well as the rest of the yard, so deck sections settle. Lifting avoids running a jackhammer next to a vinyl liner. ## How Much Does Lifting Cost in Toronto? Lifting runs $6 to $12 per square foot. Drivers: - **Area.** Mobilisation is a fixed cost, so small isolated lifts cost more per square foot than large ones. - **Lift height.** Raising a slab three inches uses considerably more material than raising it half an inch. - **Void volume.** Large voids under a slab take more foam than tight ones. - **Slab type.** Load-bearing interior and garage slabs need higher-density foam. - **Access.** Interior work needs more protection and clean-up than an open driveway. Against replacement at $10 to $16 per square foot plus demolition, disposal and a week of curing, the arithmetic usually favours lifting comfortably. ## When Lifting Is Not the Answer Lifting restores level. It does not repair concrete. If the slab has broken into multiple pieces, if the surface has scaled deeply enough to expose aggregate across most of its area, or if cracking runs through with vertical displacement in several places, then raising it simply gives you level bad concrete. In those cases replacement is the honest recommendation and we will say so, and the job moves to a new concrete driveway [/concrete-driveways/ →](/concrete-driveways/) , concrete walkway [/concrete-walkways-sidewalks/ →](/concrete-walkways-sidewalks/) or concrete patio [/concrete-patios/ →](/concrete-patios/) depending on the surface. Isolated cracks in an otherwise sound slab are handled separately under concrete crack repair [/concrete-crack-repair/ →](/concrete-crack-repair/) , and a lifted slab with a tired surface can be finished with concrete resurfacing [/concrete-overlays-resurfacing/ →](/concrete-overlays-resurfacing/) . We also look for the cause. A slab that sank because a downspout has been discharging against the foundation for five years will sink again if the downspout is not addressed. Fixing the symptom without mentioning the cause is not a service we are interested in providing.

Springdale Common questions ## Lifting & Levelling FAQs ### help How much does concrete lifting cost vs replacement? expand\_more Lifting a sunken slab costs $6 to $12 per sq ft against $10 to $16 per sq ft for full replacement, and it happens in hours rather than days. When the concrete itself is sound and only the base has settled, lifting is the smart choice. If the slab is cracked through or crumbling, replacement is better value long term. ### help What is the difference between mudjacking and polyurethane foam lifting? expand\_more Mudjacking pumps a cement slurry under the slab to raise it. Polyurethane foam injects a lightweight expanding foam instead. Foam is far lighter, cures in minutes, needs much smaller ports, and resists re-settling in Toronto clay soil where heavy slurry can sink again. We recommend foam for most GTA jobs. ### help How long does slab lifting take? expand\_more Most residential driveways and walkways are lifted in half a day. Polyurethane foam cures in minutes, so you can drive or walk on the slab the same day. There is no excavation and no waiting for concrete to cure. ### help Will the lifted slab settle again? expand\_more Polyurethane foam fills the void and also stabilises the soil it contacts, and it does not add meaningful weight to the subgrade. Where the underlying cause is ongoing, such as a leaking downspout washing out the base, we identify it, because fixing the cause is what makes the lift permanent. ### help Why do Toronto slabs sink in the first place? expand\_more Clay subgrade shrinking as it dries, poorly compacted backfill over service trenches, water washing fines out from under the slab, and settlement of engineered fill in newer subdivisions. All four leave a void, the slab loses support, and it drops. ### help How big are the injection holes? expand\_more Foam lifting uses ports around 16 millimetres in diameter, roughly the size of a pen. Mudjacking needs considerably larger holes. Ports are patched flush at the end of the visit and are barely noticeable afterwards. ### help Can you lift a garage floor? expand\_more Yes. Garage slabs, basement floors and interior slabs are all liftable with higher-density foam. It is one of the least disruptive repairs available, because the alternative is breaking out and repouring an interior slab. ### help Can you lift a slab that is also cracked? expand\_more Often yes. We lift the panels back to level and then repair the cracks, either by injection or sealing. If the slab has broken into many small pieces, lifting will not hold it together and replacement is the honest recommendation. ### help Does lifting fix drainage problems? expand\_more It usually does, because most drainage problems on residential properties come from a slab that has settled and now slopes toward the house. We check fall after the lift and confirm water runs away from the building. ### Still have questions? We answer the phone 24/7 and reply to quote requests inside two hours.
