Polyurethane Lifting

Polyurethane Concrete Lifting

Mudjacking is a thing of the past. That’s a good thing because mudjacking was a messy process that left large holes in your existing concrete and added a lot of weight to the soil beneath the concrete slab. This is exactly what you don’t want to do if weak soil was the reason the slab became uneven in the first place.

What is Polyurethane Foam Lifting?

Polyurethane foam lifting is a way to lift and level uneven concrete slabs such as driveways, sidewalks, pool decks, and patios. It’s cost-effective and much faster than tearing up the old slab and pouring new concrete.


Why Does Concrete Sink?

Concrete slabs such as sidewalks and driveways can sink into the ground and become unlevel for various reasons. The most common are:

  • Expansive soil – Expansive soil contains a high percentage of clay and because of this it expands as it soaks up moisture and shrinks as it dries out. This expanding and shrinking creates movement in the ground under the slab and over time can eventually cause a slab to sink into the ground and become uneven.
  • Erosion – Some types of soil are prone to erosion. Erosion under the slab can cause voids to form and if the slab sinks into the voids, it will become uneven.
  • Roots – We’ve all seen examples of invasive tree roots pushing up on a sidewalk or driveway.
  • Seismic activity – We probably don’t need to explain how earth tremors can cause an uneven slab.

How Does Polyurethane Foam Lifting Work?

  • Small, dime-sized holes are drilled into the affected area of the slab.
  • The polyurethane foam is injected under the slab via the holes.
  • The foam immediately begins to expand and as it does, this raises the slab.
  • When the slab has been lifted, the holes are filled with a compound that matches the color of the concrete.
  • Fifteen minutes after the repair is complete, the slab is ready for use again.
