One of the most cost-effective and innovative ways to repair your cracked or sinking concrete slab is foam foundation repair in Tulsa, OK. Our polyurethane foam lifting is an innovative new process that gets results. This specialized foam gently lifts the foundation by expanding and becoming solid in the process. The result is a strong house foundation that lasts for many years. Contact the talented team at Metro Structural Services to learn more about our state-of-the-art polyurethane foam product.
Tap into the power of foam to repair your foundation. This high-grade foam is designed specifically for slab repairs. From basements and driveways to your home’s interior foundation, it works without creating a mess or causing damage to your lawn. The primary reason for injecting foam into the ground under a foundation is to stabilize the uneven soils. The pressure created is powerful enough to lift concrete and keep it there!
Yes, our polyurethane foam has the capacity to be used for compaction grouting. This is often referred to as ‘deep injection.’ ‘Deep injection’ is a process that is patented by another commercial entity. HMI and our service division Raise Rite Concrete Lifting, does not perform polyurethane compaction grouting at this time.
It is unlikely that the concrete will crack. The greater probability is that the polyurethane gun will back up due to back pressure if you are using the Graco AP Fusion gun. This means the polyurethane will not be permitted to leave the gun and react inside the gun itself.
The gun will need to be cleaned. If you are using the HMI Fusion Pro Gun Mix Chamber Housing the probability of backing up a gun due to back pressure is nearly eliminated. This gun housing was specifically designed to withstand the back pressure that is encountered when slab jacking with polyurethane foam.
To create a void under the slab, we instruct our customers to drill into the sub-grade beneath the slab 1-2”. This will provide the space for the initial polyurethane injection to expand into and begin the lifting process.

More Effective: Foam lifts your slab as a whole.
Experienced Technicians: We are the experts in foam injections. Knowing the exact amount needed to lift your slab is vital.
Environmentally Friendly: Foam is made from recycled materials and never deteriorates or shrinks.
Injecting too little or too much foam can cause more problems with your foundation. Our team has perfected this technique and is often asked by the manufacturer to train other installers around the country. Whether you own a home or residential business, we have the tools, knowledge and skillset to create a concrete leveling solution that makes safe surfaces.
Small holes about the size of a penny are drilled every five to six feet in the foundation where polyurethane foam is injected. The foam expands and lifts the home as a whole, putting less stress on your foundation. The geopolymer foam is made from recycled materials, is environmentally friendly, and never shrinks or deteriorates.
Deep Foamjection or DF is the process of installing foam through pipes into the subgrade. Results, injection point layout, depths, and how much foam is required are custom based on:
Within this manual, we will cover best practices and strategies along with case studies that can be applied to various projects. Each project will have different challenges and results based on the above factors. The more information you have about these conditions, the more effective the implementation or your strategy can be.
The primary objective for injecting foam into the ground is to stabilize the unstable soils. Pressure built up by installing this foam into the subgrade can be great enough to lift concrete. The challenge to lifting is to contain the foam and continue to build enough pressure to lift. Concrete will move until it is easier for the foam to travel elsewhere.
The foam will build pressure, but it can take an unknown amount to accomplish this. Injecting at multiple depths or multiple injection points simultaneously can increase the likelihood of lifting with foam installed. Often foam installed directly under the slab can be more effective to manipulate a slab back into place.
Deep Foamjection can be used to improve soils, install ‘curtains’ to block seepage (seawall repair), and stabilize and lift concrete slabs, roadways, slab on grade or foundations. Foam can be installed as a repair to failed soils or in preparation for building on a site with known soil issues. More advanced applications involving structures can be approached with standard best practices but may need engineered support.
