Concrete Leveling & Concrete Crack Repair

The sunken and cracked concrete around your Chester home is both an eyesore and a safety hazard. Whether you've experienced an uneven patio or cracked driveway, the problem is likely to get worse. Luckily, we offer innovative solutions!

To level and lift sinking concrete, our experts use PolyLevel, a superior polyurethane foam. Here's how it works: small holes are drilled in the concrete, the foam is injected and the expanding foam lifts the concrete. The majority of contractors you call will recommend mudjacking instead of foam. However, mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel

For cracked concrete repair, we offer NexusPro, an ultra-flexible concrete sealant that repairs cracks and joints. NexusPro can be applied year-round and is resistant to extreme weather patterns, temperature fluctuations, and more, ensuring long-lasting results.

We Fix
  • Cracked Driveways
  • Uneven Patios
  • Sinking Sidewalks      

  • Uneven Concrete
  • Sunken Pool Decks
  • Highway & Commercial Issues

An approximately 17 year old addition is settling. There are numerous interior cracks in the walls, the doors don't shut properly, and there is a noticeable tilt in the floor where the old & new section meet.

Our basement is consistently wet when it rains and stays wet for a very long time. I am interested in what it would cost to get a sump system installed in the basement to keep things dryer.
Vicinity of Greycourt Rd in Chester

Our unfinished basement has a musty smell that we would like remedied correctly. There are no major concerns such as flooding or leaks, but there may be some cracks. We may look to finish the basement in the future. We usually do not answer any phone calls from numbers that we do not know, so please leave a message on the voicemail if you contact us by phone. Thank you.

Cracked and uneven concrete patio and pool deck.
Vicinity of Ramlow Road in Chester
I recently purchased a house that I have demoed to down below the crawl-spaced floorboards. This house was built on compromised piers and I currently have an architect creating drawings for the design for front and mid piers. The house is mildly jacked and should have full access for excavation with a small machine. I was wondering if you would be interested in providing an estimate for this work.
