Foam Injection Concrete Leveling
A-1 Concrete Leveling offers High Density Polyurethane Foam Injection for concrete leveling, stabilization, and void filling applications. Foam injection offers similar great results as our grout-based method. With a range of installation methods and product performance characteristics, our foam method may be the best and most cost-effective solution for your leveling needs.
The Foam Injection Concrete Leveling Process
Foam injection concrete leveling uses a polyurethane material. It is injected under the slab as a liquid and expands before curing, filling any voids and raising the concrete. In only seconds it will reach its final volume. After curing, it will never lose its density and will maintain its compressive strength. Our foam leveling material won’t break down or wash out from water.
Foam injection concrete leveling can be done quickly, with the surface being usable immediately. Injection hole sizes (5/8-inch, or about the size of a dime) are smaller than our stone slurry grout leveling holes, potentially making it a good solution for highly visible areas or decorative concrete surfaces.
Best Uses for Foam Injection Concrete Leveling
There are many times when foam injection is the best repair process to address a problem. These include:
- Areas Where Cleanliness is Important - Due to the ability to use fewer and smaller holes, minimal dust is created in preparing the surface. Additionally, because there is a mechanical connection between the injection equipment and the slab, minimal material is exposed to the surface or surroundings.
- Sensitive or Expensive Surfaces - Because foam injection uses small (3/8”) holes, it is an ideal repair method for settled slabs which have decorative coatings, surface treatments or other characteristics, such as brick and stone overlays. Injection holes can be patched with stained concrete to blend in with the surrounding material. For repairing slab floors covered with wood, we cut a small access area to reveal the concrete floor, and then secure the wood back into place after leveling is completed. For carpeted areas, small squares can be cut to reveal the concrete surface, and then be glued back down after leveling.
- Hard to Reach Work Sites - Foam injection equipment can be transported to work sites that are inaccessible to grout trucks, making it an effective solution to virtually any job location.
Cautions When Considering Foam Injection Concrete Leveling
Overall, foam injection concrete leveling will give you a satisfactory result, however, for many applications it is inferior to our stone slurry grout concrete leveling solution. It doesn’t have the ability to fully fill voids as well as stone slurry grout can. And, although our technicians are highly trained in both methods, foam injection concrete leveling can be harder to control, as its lifting capabilities are based on expanding foam, rather than the consistent filling of the void with our grout solution. Also, foam is almost always more expensive.

A-1 Concrete has done two jobs for me recently. The most difficult was replacement of the 36'x5.5' aggregate concrete surface of the porch of my home. They removed the 30 year old cracked and sunken concrete surface, tamped down the sand and gravel fill below the surface, installed all new flashing and plastic and poured a new aggregate surface. It looks beautiful and blends nicely with the aggregate concrete sidewalk in front of the porch. They also installed three tie rods and decorative cast iron anchor plates in the shape of stars to stabilize the exterior brick wall of the porch. The rods tie back through the main foundation wall at the back of the porch. This was a difficult bit of work and they completely met my expectations. They returned several times to get the cast iron anchor plates installed perfectly. A wonderful job which repaired the porch and added a beautiful architectural detail to the house!! The next was a sidewalk leveling and repair at my local church where I serve as a deacon. They leveled 10 sidewalk slabs in our 27 year old concrete sidewalk. They did a great job on the badly cracked and uneven sidewalk and their pricing was very reasonable. They were on time and did great work. A very good value!
