Foam Jacking with Polyurethane Injection

We utilize a proprietary injection process referred to as foam jacking to stabilize soils, fill voids, and lift and level concrete slabs.

Our no-dig polyurethane foam jacking solution is fast, effective, and can save your existing structure at a fraction of the cost of replacement. With polyurethane injection,  we can achieve a variety of goals, from lifting and leveling to void-filling and soil stabilization.

Why Foam Jacking?


  • Lifting and Slab Realignment
  • Filling Voids Underneath the Slab
  • Stabilizing and Strengthening Weak Soils Beneath the Slab
  • Preventing Future Soil Washout
  • No Excavation and Minimal Mess
  • Avoid Having to Pour a New Slab
  • Environmentally Friendly Polymers


Our polymer injection application doesn’t require excavation or trenching, 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.

Our polymers are light-weight and add minimal weight to the area. This is a major advantage because often times treatment is required because the added weight is to 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.

Our polyurethane injection process, also known as foam jacking or slab jacking, is an ideal application for rehabilitating structures.  We accomplish this by drilling small 5/8″ holes through the slab, inserting 1/2″ rods to the weak soil locations, and injecting a high-density polyurethane underneath the slab.

Once injected, the polyurethane expands up to 25 times its initial volume and fills any present voids.  The polymer expansion direction is controlled by the injection technique and volume of polyurethane injected.  This allows for the experienced Concrete Leveling Solutions team to accomplish your goals, whether lifting and realigning the slab, or void-filling and stabilizing the soil underneath.
