Sunken slabs lifted back to level with mudjacking — faster and 50–70% cheaper than full concrete replacement. Trip hazards eliminated in one visit.
Concrete slabs sink when the material beneath them loses volume. In Calgary, the primary causes are: erosion of sub-base material by water migration, consolidation of poorly compacted fill, frost heave that shifts soil position seasonally, and settlement of backfill placed during original construction near foundations.
Mudjacking (also called slabjacking or concrete lifting) restores the sub-base support that was lost. We drill small holes through the slab, pump a cement-based slurry beneath it under controlled pressure, and as the slurry fills the void it lifts the slab back toward its original position. The holes are patched and the surface is ready for use within 24 hours.
Mudjacking works best when the concrete slab itself is structurally sound — it has settled but hasn't broken apart. Good candidates include driveways with sunken sections, front steps that have settled away from the house, sidewalks with trip hazards, and garage floors with unlevel sections. If the concrete is badly deteriorated or broken into multiple independent pieces, replacement may be more appropriate — we'll tell you honestly which situation you're in.
A typical Calgary driveway section mudjacked: $800–$2,000. The same section replaced: $2,500–$6,000. For a full driveway, the difference is even more dramatic. Mudjacking also avoids the disposal cost and disruption of demolishing and removing existing concrete.
Mudjacking restores support under a slab without tearing it out — at 50–70% less cost than full replacement.
