Sinking Driveway Slab in Monroe Township, NJ

This Monroe Township driveway had settlement issues where the driveway and the garage met. The homeowner didn't like the way it looked nor the bump his car had to drive over each day he drove in and out of his garage. He called Quality 1st for a free estimate! A Design Specialist recommended the PolyLevel System which would easily permanently lift the driveway back to its desired level, removing the small bump. The homeowner was very pleased to see how quick and easy it was, plus how well the crew cleaned up!

The homeowner in Williamstown, NJ noticed their one driveway slab had settled a little in their driveway. At first they thought nothing of it but over time their foot would start to catch it on the way to the car. Realizing that one of them could get hurt they contacted Quality 1st to take a look to see what could be done. System Design Specialist Maurice Robinson recommended PolyLevel. A small whole was drilled into the slab which pumped a small amount of PolyLevel foam solution underneath. The foam then expands and hardens raising the slab back to its original level.

Basement Waterproofing & Crawl Space Repair

Basements and crawl spaces consistently have issues with water, mold and rot. To prevent these problems from occurring in the future we install a patented interior drainage system. Water and moisture that enters the basement is captured, controlled and safely removed via the basement drain before you ever notice it. The drainage system also works as part of crawl space encapsulation. 

We Provide:
  • Basement Waterproofing
  • Crawl Space Encapsulation
  • Exclusive, Patented Products
  • Humidity Control
  • Egress Windows
You Receive:
  • Permanently Dry Basement

We also fix basement leaks with permanent basement leak repair. With our system in place there is no need to fear basement flooding. We want your basement to be safe for years so our work comes with a transferable lifetime dry-basement warranty. 

Foundation Repair & Concrete Leveling

Whatever the issue we are the trusted foundation repair contractor. Our foundation repair experts will visit your home, identify the issue and recommend the right solution. We provide permanent foundation repairs using non-invasive methods. There is no need to tear up your entire yard to fix the foundation.

Repairs for:
  • Wall Cracks
  • Bowing Walls
  • Uneven Floors
  • Settling Foundations
  • Uneven Concrete Slabs       
We Use:

If you are looking for the right foundation repair company, you found it. Let's get started.
