We Treat Your Home Like Our Own
From hillside neighborhoods like Mount Washington to patios near the Allegheny and Monongahela Rivers, concrete slabs in Pittsburgh face constant pressure from soil movement and moisture. Sidewalks, porches, and patios often sink as water washes away supporting soil beneath them. Slabjacking is a cost-effective solution that restores stability without tearing out existing concrete.
Acculevel has repaired thousands of concrete surfaces across the region. Acculevel was founded in 1996, and is well known in the industry for repairing foundations, basements, and crawl spaces. We raise and repair concrete structures for thousands of customers per year.
In Allentown, erosion often occurs beneath sidewalks and patios due to heavy rainstorms and inconsistent drainage, especially in areas near Cedar Crest, South Mountain, and older residential neighborhoods. Water that repeatedly saturates the soil and drains away slowly removes the supporting ground beneath concrete slabs.
Lehigh Valley soils often contain clay and silt, which expand when wet and shrink during dry periods. Combined with freeze-thaw cycles common in eastern Pennsylvania, this movement stresses concrete slabs over time. Poor soil compaction during construction increases the likelihood of settlement.
As concrete settles unevenly, cracks form and create tripping hazards along walkways and patios. Sunken slabs may also redirect water toward the home’s foundation, increasing moisture levels in basements or crawl spaces. Over time, this can damage structural wood and allow biological growth to develop.Water permeating into your home can cause rotting in the structural wood flooring system (sill plate, floor joists, etc) and allow mold to flourish and grow.
Concrete sidewalk and patio repair in Allentown, PA often requires slabjacking to correct sinking slabs caused by soil compaction and moisture changes. The process begins by drilling small holes into the concrete, followed by injecting a lifting material beneath the slab to fill voids and restore elevation.
Homes near Hamilton Street and older neighborhoods like West End commonly experience concrete settlement due to freeze-thaw cycles. Acculevel uses polyurethane foam rather than heavy slurry. The foam expands quickly, allowing for controlled lifting and reducing the risk of future settling under sidewalks and patios.
In this video, one of our knowledgeable experts explains why we choose to perform slabjacking:
Concrete sidewalk and patio repair in Allentown is faster and more efficient with slabjacking. The polyurethane foam cures quickly, allowing patios near the West End Theatre District, Cedar Beach Park, and surrounding neighborhoods to be used almost immediately. Garage slabs can typically support vehicles within an hour, minimizing disruption to daily routines. This quick cure time is especially beneficial during Allentown’s fluctuating seasonal temperatures. Mudjacking requires longer curing and is more affected by moisture conditions.
Slabjacking repairs are completed without tearing up lawns or nearby landscaping, which helps preserve curb appeal. Crews can access sidewalks and patios without heavy machinery, keeping disruption to a minimum. The job site remains clean, with little more than drilling dust to remove afterward. Unlike slab replacement, there is no need for concrete trucks, forms, or disposal containers. This makes slabjacking ideal for residential neighborhoods.
Slabjacking works with the existing concrete slab, so the costs are limited. They depend more on the size of the slab being lifted, and the amount of void under the slab. (The larger the gap, the more material is required.) The costs to replace concrete can be double the price of slabjacking. For more details on costs, please review our article on costs comparisons.
