We Treat Your Home Like Our Own
Homes near the Susquehanna River and older Harrisburg neighborhoods often experience soil settlement beneath concrete slabs. Sidewalks and patios can crack or tilt as the ground shifts. Slabjacking is a practical way to correct these issues without major disruption.
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. Acculevel specializes in concrete sidewalk and patio repair in Harrisburg, PA, offering long-term leveling solutions.
Proximity to the Susquehanna River means Harrisburg experiences frequent moisture exposure. Water runoff and aging drainage systems in areas like Midtown and Camp Hill can cause erosion beneath concrete slabs
Central Pennsylvania soils often include clay that reacts to seasonal moisture changes. Combined with winter freeze-thaw cycles, this movement causes slabs to shift over time.
Uneven slabs create trip hazards and may redirect water toward the foundation. Long-term moisture exposure can damage structural components and contribute to biological growth inside basements or crawl spaces.
Concrete sidewalk and patio repair in Harrisburg, PA often involves slabjacking to fix uneven slabs affected by erosion and drainage issues near the Susquehanna River. The process starts with drilling small holes into the concrete and injecting material underneath to lift and stabilize the slab.
Neighborhoods like Midtown and Camp Hill commonly see concrete settlement due to moisture-heavy soil. Acculevel uses expanding polyurethane foam, which reacts quickly and allows for precise lifting, resulting in a more controlled and durable repair.
In this video, one of our knowledgeable experts explains why we choose to perform slabjacking:
Concrete sidewalk and patio repair in Harrisburg is faster and more practical with slabjacking, especially in areas affected by seasonal moisture and river-adjacent soil conditions. The polyurethane foam cures within minutes, allowing homeowners in Midtown, Uptown, and neighborhoods near the Susquehanna River to safely walk on repaired patios the same day. Garage floors are typically ready for vehicle traffic within an hour, minimizing disruption for busy households. This quick cure time is especially helpful during spring rains and fluctuating temperatures common in the Harrisburg area. Mudjacking, by comparison, requires longer curing and is more susceptible to moisture-related delays.
Slabjacking in Harrisburg is completed using compact equipment that can park easily in residential driveways or along city streets. Crews rarely need to cross lawns or disturb landscaping, which helps preserve curb appeal in established neighborhoods. The process creates minimal mess, limited mostly to small amounts of dust from drilling injection holes. Unlike slab replacement, slabjacking avoids loud jackhammering, concrete debris, and extended construction timelines. This makes it a cleaner and quieter solution for residential properties.
Slabjacking keeps concrete sidewalk and patio repair in Harrisburg more affordable by restoring existing slabs instead of replacing them. Costs depend on the size of the slab and the amount of settlement beneath it, which is common in areas with erosion or poor drainage. Because demolition and re-pouring are avoided, labor and material costs remain lower. Full concrete replacement often costs significantly more and can result in noticeable differences in color and finish.
