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

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.
