Effective Concrete Leveling in MD, NVA & DC

Concrete Slab Jacking Inc. fixes sunken concrete without total replacement. We raise concrete from beneath to adjust an uneven slab. Our technique saves you time and money. We inject a strong base material composed of polyurethane foam under the existing concrete to raise it back to alignment. This closes gaps and separations in the slab, providing lasting stability with robust and reliable material. Slab jacking is the perfect solution for sinking slab floors, driveways, sidewalks, patios, and more and our repairs come with a 3 Year Warranty.

Why Does Concrete Sink?

When concrete is installed on poorly compacted dirt, the soil supporting the heavy slab may shrink and erode. Uncompacted fill dirt placed creates void spaces that can aggravate as pressure from slabs removes air and water from the soil. This causes the soil to sink along with the slab, resulting in uneven and unsafe concrete. If your driveways, sidewalks, garage floor or basement is cracked or damaged, don’t resort to replacing the entire concrete slab. We offer a much better cost-effective solution without the disruption of replacement. Our method of raising concrete is quick, simple, and practical, with minimal mess or inconvenience.

How Concrete Raising Works

We inject HMI Polyurethane expanding foam underneath sunken concrete slabs. First, we drill small, 3/8-inch holes at strategic locations on the sunken slab. Then we pump and inject the polyfoam underneath the slab using sealed, specialized equipment. The polyfoam expands and fills the voids as well as compacts soils beneath the concrete. As the foam expands and hardens, it puts pressure on the slab, lifting it back to a level position. Once the foam raises the concrete to the desired level, we patch the holes with grout and trowel smooth until they are nearly invisible. This technique is also known as the following:

  • Concrete lifting
  • Concrete leveling
  • Concrete raising
  • Void filling
