We Treat Your Home Like Our Own
Concrete sidewalks and patios are common throughout Charleroi, from homes near Fallowfield Avenue to properties close to the Monongahela River. Over time, shifting soil and water runoff can cause concrete slabs to sink, crack, or become uneven. Sidewalks, patios, garage floors, and pool decks are especially vulnerable in areas with older infrastructure and seasonal moisture changes.
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 Charleroi, concrete sidewalks and patios often sink due to erosion beneath the slab. Heavy rainfall along the Monongahela River corridor and aging drainage systems in neighborhoods near McKean Avenue or Fallowfield Township can wash soil away over time. When water repeatedly saturates the ground and then drains off, it pulls supporting soil with it. Broken underground pipes or poorly directed downspouts can accelerate this erosion, especially around older homes.
The soil in and around Charleroi contains a mix of clay and silty materials that expand when wet and shrink during dry periods. Seasonal freeze-thaw cycles common to Washington County further stress the soil beneath concrete. Over time, this movement causes slabs to shift, especially when the original soil wasn’t compacted properly before the concrete was poured.
Concrete rarely settles evenly. One side of a patio or sidewalk often drops lower, creating trip hazards near steps, walkways, or drive approaches. Uneven concrete can also redirect water toward your home, increasing moisture around the foundation and crawl space. Left unaddressed, this moisture can damage structural wood components and encourage biological growth inside the home.
Slabjacking for concrete sidewalk and patio repair in Charleroi, PA works by stabilizing sunken concrete through targeted injection beneath the slab. Small access holes are drilled into the affected sidewalk or patio, and a lifting material is injected into the empty spaces below. As this material fills voids caused by erosion or shifting soil near areas like McKean Avenue and neighborhoods along the Monongahela River, pressure builds and raises the slab back toward its original position.
Many older homes in Charleroi experience concrete settlement due to heavy rainfall and changing soil conditions common in Washington County. While traditional mudjacking uses a cement-based slurry, Acculevel uses expanding polyurethane foam. This foam reacts quickly, allowing precise control during the lift and creating a lightweight, long-lasting solution for uneven concrete surfaces.

For homeowners needing concrete sidewalk and patio repair in Charleroi, slabjacking offers fast results with minimal disruption to daily life. The polyurethane foam cures within minutes, allowing patios near Fallowfield Avenue, Lincoln Avenue, and neighborhoods along the Monongahela River to be walked on almost immediately. Garage floors are typically ready for vehicle traffic within an hour, which is especially helpful for older homes with limited parking options. Unlike mudjacking, slabjacking is far less affected by Charleroi’s moisture-heavy soil conditions. This means repairs stay on schedule even after heavy rain or seasonal ground saturation.
Slabjacking in Charleroi is completed using compact equipment that can park directly in a driveway or along residential streets without causing congestion. Our crews rarely need to drive across lawns, which helps protect landscaping in tightly spaced neighborhoods. The process generates very little mess, usually limited to minor dust from drilling small injection holes. Compared to concrete replacement, slabjacking avoids noisy jackhammers, large debris piles, and unnecessary disruption to surrounding properties. This makes it a practical choice for established residential areas.
Slabjacking works with your existing concrete, keeping costs significantly lower than full slab replacement. Pricing is primarily based on the size of the sidewalk or patio and the amount of void beneath the slab, which is common near river-adjacent properties in Charleroi. Because no demolition or re-pouring is required, labor and material costs remain controlled. In many cases, replacing concrete can cost twice as much and still result in visible mismatches in color and texture. For more details on costs, please review our article on costs comparisons.
