Concrete Lifting Sherwood Park

Concrete lifting in Sherwood Park addresses one of the most common structural problems Central Alberta homeowners face: concrete slabs that have settled unevenly due to soil erosion, freeze-thaw cycles, or poor original compaction. Concrete lifting, also called mudjacking or slab jacking, is the process of injecting a stabilizing material beneath a sunken slab to raise it back to its original elevation. This case study documents a residential driveway restoration completed by Merit Home Services (meritconcrete.ca), illustrating the technical process, material specifications, and measurable outcomes from start to finish.

The Problem: A Sherwood Park Driveway with 2.5 Inches of Differential Settlement

A homeowner in Sherwood Park contacted Merit Home Services after noticing that the approach panel of their double-wide concrete driveway had settled approximately 2.5 inches below the garage apron. The resulting trip hazard had also redirected surface drainage toward the foundation wall - a secondary problem that accelerates soil erosion and can compromise basement waterproofing over time. The driveway was structurally sound, showing no major cracking or spalling in the slab body itself. The issue was entirely subsurface: a void had formed beneath the slab due to years of fine soil migration through the drainage layer. Full replacement would have required demolition, disposal, reforming, and a multi-day cure period - at an estimated cost 3 to 5 times higher than lifting.

The Approach: Cementitious Grout Injection with Precision Port Placement

Merit Home Services assessed the slab and identified two primary void zones using a combination of visual inspection and sounding - tapping the surface to detect hollow resonance beneath. The technician drilled 1.5-inch diameter injection ports at calculated intervals across the settled panel, typically spaced 18 to 24 inches apart in a staggered grid pattern to ensure even grout distribution beneath the slab.

Unlike polyurethane foam lifting, which relies on chemical expansion and can introduce uneven upward pressure, Merit uses a cementitious grout mix - a engineered blend of Portland cement, fine aggregate, and water - pumped at controlled pressure through each port. This grout achieves 4 to 5 times the compressive holding strength of standard foam, making it significantly more resistant to future settlement under vehicle load. The grout fills voids, encapsulates loose soil, and cures into a dense, load-bearing substrate that becomes a permanent part of the sub-base.

Key Insight: Cementitious grout does not compress or degrade over time the way foam can under repeated freeze-thaw stress - a critical advantage in Central Alberta's climate, where ground temperatures cycle dramatically between seasons.

Lift was achieved gradually over multiple injection passes, with the technician monitoring elevation using a digital level calibrated to 0.1-inch increments. The slab was raised 2.4 inches over approximately 90 minutes of active injection, bringing it to within 0.1 inches of the target flush elevation with the garage apron. Ports were then plugged with matching concrete mix and finished flush.

The Result: Level Surface, Redirected Drainage, No Replacement Required

The completed lift restored proper positive drainage away from the foundation wall, eliminating the water infiltration risk. The homeowner avoided full driveway replacement and the associated disruption. Total project time was under three hours, including setup, injection, port patching, and cleanup. The cured grout substrate is designed to support standard residential vehicle loads - up to 8,000 lbs per axle - without recompression or further settlement under normal conditions.

Merit Home Services provides concrete lifting services across Edmonton and Central Alberta, including Leduc, Camrose, Spruce Grove, St. Albert, and Sherwood Park. Their cementitious approach is particularly effective in areas with heavy clay subsoil or significant seasonal frost depth - both defining characteristics of the Edmonton metro region's geology.

Why Concrete Lifting Sherwood Park Homeowners Choose Grout Over Foam

The choice of lifting material has long-term consequences that go beyond the initial repair. Polyurethane foam expands rapidly and can be difficult to control in large void spaces, sometimes creating new differential pressure points within a single slab panel. Cementitious grout flows into void geometry naturally, conforming to irregular cavities without the risk of over-expansion. For driveways, which experience repeated dynamic loading from vehicle traffic, the higher compressive strength of cementitious grout - typically 3,000 to 4,000 PSI at 28-day cure - means the sub-base restoration is engineered to last. Homeowners researching concrete lifting in Sherwood Park will find that this material distinction is the primary reason Merit Home Services' results hold up longer in Central Alberta's demanding environment.
