The driveway of a home in Lawrenceville, NJ had several concrete slabs that were settling into the ground.

Our team injected PolyLevel foam beneath the slab, lifting the settled concrete back into place. The homeowner was overjoyed to finally have a level driveway.

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
  • Clean Protected Crawlspace
  • Protection against Mold
  • Improved Home Value
  • Less Leaks & Better Energy Efficiency

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: 
  • Wall Anchors

Along with general foundation problems we also fix sunken concrete slabs using PolyLEVEL. PolyLEVEL is an expansive polyurethane foam that fills in the gaps beneath the sunken concrete and lifts it back up to a level position. It also does not erode or wash away. If you are looking for the right foundation repair company, you found it. Let's get started.

The house was jacked up previously. We purchased the home about 5 years ago and I noticed that the floor is not level in the dining room. I believe the house needs to be reassessed. Additionally, I'd like information concerning the condition of the basement (excessive moisture) and other foundation issues.

I want to have a wall with a door in the middle to separate the one basement room into two. It is about 23 ft long. Please do not call me, send me an e-mail letting me know when could you come to see the project and give me an estimate. My name is Martha Thank you
Project Location: Lawrence Township, NJ
During heavy downpours, our basement walls sometimes have damp spots and during especially rainy periods, a pinhole leak may appear. I've used hydraulic cement as a fix but we're hoping to finish our basement in the future and would like to take care of any wetness issues.
