Rocking Slab Repair
Statewide’s rocking slab repair solution is a no-excavation application that is quicker and more cost-effective than traditional methods.
Rocking Slab Repair with Polyurethane
Rocking and uneven concrete slabs can cause delays, damage, and safety concerns for businesses. The days of replacement are over with concrete raising with polyurethane foam jacking. Our rocking slab repair application stabilizes rocking slabs quickly and cost-effectively. The process is also minimally-invasive, allowing the repair to be performed quickly without excavation and with minimal impact to your business operations.
Benefits of Stabilizing Rocking Slabs with Polyurethane:
- No excavation is required
- Injections are made through the slab
- Fills voids and stabilizes the soil against future erosion
- Densifies and compacts soils
- Pushes any water from underneath the slab
- Polyurethane is environmentally inert and will not leach chemicals into the water
How Rocking Slab Stabilization Works
Once injected, the polyurethane aggressively seeks out voids, like how water seeks the path of least resistance. After a few short minutes, the polymer reacts and begins to expand throughout the voids and the weak points in the soil. The polyurethane then begins to use expansive pressure to stabilize, lift, and level the slab in minutes.
Step 1
Polyurethane is injected into the void through the slab

Injections are made through 5/8′ holes that are drilled through the slab.
Step 2
Polyurethane begins to expand, packing the voids and weak soils

Once injected, the polyurethane travels throughout the voids and expands up to 25 times its original volume through the soil.
Step 3
Once the void is filled, polyurethane packs soils and lifts slab.

After filling voids, the polyurethane continues to expand, packing soils, and lifts the slab. The polyurethane cures to 95% capacity within 25 minutes.
Why Our Polyurethane Solutions Work
Our polyjacking process is ideal for stabilizing rocking slabs. Lifting concrete with polyurethane foam is cheaper than concrete replacement. Polyjacking is a reliable process used for years by many concrete leveling contractors.
Our polymer injection application is a no excavation rocking slab stabilization solution, allowing for minimal impact to your structure. Our project footprint is minimal, requiring a small trailer, a hose running from the trailer, and small 5/8″ holes that are drilled through the structure to give us access to drive our rods to target locations and inject our high-density polyurethane.
We use polyurethanes that are light-weight, reducing added weight to the area. This is a major advantage because often times treatment is required because a structure’s weight is too much for the geology of the area.
Our polymers set up to 95% capacity within 15 minutes, unlike other solutions which require 24-48 hours and ideal soil conditions. After 15 minutes, the material can be driven on and take on heavy loads
Our polymers are environmentally inert and have no impact to the environment or groundwater.
Not only is our process the fastest and most effective foundation and slab lifting application, but it is the most cost-effective too.
