We Treat Your Home Like Our Own

Concrete sidewalks and patios throughout Lancaster — from Manheim Township to neighborhoods near Central Market — can sink as soil compresses beneath them. Moisture, erosion, and age all contribute to uneven slabs. Slabjacking is an efficient solution that restores concrete quickly.
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.


Lancaster’s mix of urban and rural drainage systems can contribute to erosion beneath concrete slabs, especially near older homes and farm-adjacent neighborhoods. Poorly directed runoff slowly washes soil away beneath sidewalks and patios.
The region’s clay-based soil expands when wet and shrinks during dry periods. Freeze-thaw cycles further contribute to soil movement, especially when the slab was poured over inadequately compacted ground.
Uneven concrete creates trip hazards and water-drainage issues. Slabs that slope toward the home increase moisture exposure around the foundation, potentially damaging structural wood and encouraging biological growth.
Slabjacking for concrete sidewalk and patio repair in Lancaster, PA works by lifting sunken concrete through injection beneath the slab. Small holes are drilled, and material is pumped below to fill voids created by soil compaction and moisture changes common in the region.
In neighborhoods near downtown Lancaster and surrounding farmland areas, shifting soil can cause patios and sidewalks to settle unevenly. Acculevel uses polyurethane foam, which expands quickly and provides accurate lifting control, making it a dependable alternative to traditional mudjacking.
In this video, one of our knowledgeable experts explains why we choose to perform slabjacking:
Concrete sidewalk and patio repair in Lancaster benefits from slabjacking’s fast-curing polyurethane foam, allowing homeowners to use repaired surfaces quickly. Patios near Downtown Lancaster, Manheim Township, and areas around Buchanan Park can often be walked on almost immediately after repairs. Garage slabs are typically ready for vehicles within an hour, which is ideal for busy households and shared driveways. This quick cure time is especially helpful during Lancaster’s wet spring and fall seasons. Mudjacking requires longer curing and is more affected by soil moisture.
Slabjacking in Lancaster minimizes disruption by avoiding demolition and heavy construction equipment. Crews can access sidewalks and patios without driving across lawns or damaging surrounding landscaping. The repair process produces very little mess, usually limited to small amounts of concrete dust. Compared to slab replacement, slabjacking eliminates the need for concrete trucks, forms, and debris removal. This keeps properties clean and reduces overall project impact.
Because slabjacking lifts and stabilizes existing concrete, it keeps repair costs lower for Lancaster homeowners. Pricing is influenced by slab size and the amount of void beneath the concrete, often caused by soil settlement in residential areas. Avoiding replacement helps reduce material and labor expenses. In many cases, full slab replacement costs significantly more and can leave visually mismatched concrete sections.
