Concrete Lifting and Leveling

Poor water mitigation or soil compaction will eventually cause your concrete to settle. It’s a given. The root causes we often see are clogged gutters, no gutters, no downspout extensions, poor grading, and low spots, to name a few. When you begin to see a settlement of more than 1/2”, it’s better to address it sooner than later. A rapid response will increase the odds of effectively salvaging the existing concrete, which saves money compared to ripping out and replacing the concrete. With our technology, there’s zero excavation required and minimal disturbance to lawns, shrubs, etc., which makes most repair jobs a one-day project.

To lift your sinking slab back up, our team injects structural polyurethane (expandable foam) under your concrete. This two-part material will mix and run like water for the first 10-15 seconds, penetrating the voids in the soil. Then it begins to expand. The soils beneath start tightening up as the voids fill, and the foam eventually begins lifting the concrete back into place. The result is reducing that trip hazard or filling the void so the concrete slab is stabilized. Contact us today for a free inspection.

We Can Lift:

  • Sidewalks
  • Porches and Stoops
  • Garage Floors
  • Driveways
  • Pool Decks
  • Basement Floors

Void Fills

The soil under your concrete or structure can settle under its own weight or due to water migration issues. This can cause voids and settling of the slab, porches, front stoops, garage floors, etc. We use a combination of long rods to reach back into the voids to precisely deliver the material where it’s needed. Then we use the polyurethane gun to deliver polyurethane straight from the tip under high pressure.

Soil Stabilization

Our soil stabilization techniques are used to stabilize soil under an existing structure. We drive rods down into the soil on an approximate 4’ grid pattern and pump material in each vertical foot of soil mass we are stabilizing. Deep injection techniques use 1/2”-1” rods to deliver the material deeper below the surface, anywhere from 5’-20’, stabilizing the existing soil mass. The goal is to increase the bearing capacity of the existing soil mass so we can ensure the slab or structure does not continue to settle.

We use these techniques to remediate sinkholes, seawalls, backfilled soil zones, bridge embankments, or retaining walls that were not properly compacted or have had water migration issues. The materials we use are very light compared to concrete, which can be critical when more weight on a wall or backfill zone is not an option. These materials are extremely dense and strong and can support between 7000lbs per cubic ft up to 14,000 lbs per cubic ft, based on the material used.

Wall Stabilization

Think of your walls as the bones of your home or business. Without stable walls, you can jeopardize the integrity of the structure. If left untreated, your walls can move beyond the point of repairing them. If you see long horizontal lines along your walls or stair-step cracks, it’s best to have them looked at sooner than later.

We stabilize your wall by installing carbon fiber strips engineered for lateral support. These strips adhere to your wall and act as a brace to the structure. The tensile strength of carbon fiber is stronger than steel. Scientists even use this technology on spacecraft. Our carbon fiber strips are ideal for CMU block walls, poured concrete walls, and brick mason walls. They can be installed on indoor and outdoor applications. Best of all, they are very low profile and can be painted over or have a wall framed over them after installation. This technology is about half the price of steel tie-backs.
