Lift and level sunken concrete driveways, pool decks, and patio slabs with lightweight polyurethane foam.

Is sunken concrete creating unsightly trip hazards around your home or business?

Sinking concrete is often caused by excessive weight, expansion and contraction due to changes in the weather, and erosion of supporting soil due to the movement of water below the surface. When concrete sinks, you are left with dangerous trip hazards and potentially water pooling issues that could accelerate soil settlement.

Polyurethane foam injection is a cost-effective and long-lasting solution for concrete raising

In most cases, there is no need to dig up and replace cracked and sunken concrete slabs. With our simple three step process we are able to relevel your concrete for a fraction of the cost of replacement in just a few hours.


In just 15 minutes after injection, slabs are ready to be walked on or support vehicular traffic.


The lightweight foam material does not contribute to future soil settlement, unlike the heavy material used in mudjacking.


Save up to 50% compared with traditional concrete slab replacement.


No excavations are required to lift sunken concrete with polyurethane foam injection.


Our polyurethane foam is inert and does not react with soil or moisture; it does not leach harmful chemicals into the soil.


Once cured, the polyurethane material will not wash away.

How does the concrete leveling process work?

Drill Holes

Drill Holes

Small holes are drilled through the affected slab.

Patching and Caulking

Injection and Lift

The two-part polyurethane foam is injected through the slab. The foam expands, raising the slab back into place.

Patching and Caulking

Patching and Caulking

Holes are patched and joints are caulked.

Polyurethane foam can be used to level and lift:

Concrete Leveling FAQ

An average concrete lifting job ranges from $1-$3K+

In most situations, Epp Foundation Repairs polyurethane foam injection repairs are permanent. The material that we use to complete repairs will last a lifetime. It cures within minutes as a solid, impermeable structure that adheres directly to the concrete.

The foam itself does not break down. Sunlight exposure is the only thing that can break it down. But the foam is under the slab and not exposed to sunlight. It’s closed-cell; water can’t penetrate it. So if you see some signs of failure it’s most likely because the soils are moving underneath our material. It’s not because of the material itself. In other words, as long as the substrate (the underlying soil) continues to perform, the polyurethane can last forever. It’s that soil that poses the primary risk to your repair.


Yes. On concrete over 7 years old, Epp Foundation Repair warrants slabs raised with PolyLift® Concrete Lifting for a period of (5) years from the original date of installation. Contact us for details and limitations.

It is usually accomplished in a few hours depending on the job and the size. 90% of our projects are completed same day.

We can usually get positive results on approximately 90% of all of our projects. It is rare that we can’t accomplish a satisfied fix for the customer. Polyurethane foam does not fix slabs that are raised by tree roots.

Typically, our customers never notice the patched holes. The patching material that we use when cured blends into existing concrete very well. The holes that we drill are no bigger than a dime so it is difficult to notice where we drilled when we are finished.

No. Removal and replacement of the concrete is the only way to drop a concrete slab.

Most of the time yes. It does depend on the height of the home and the structure but we can usually achieve positive slope away from the home if need be if the structural height allows.

Mudjacking is sand, water, and a little bit of Portland cement to give it some stickiness, some cohesion. Without it, it’s just sand. It’s susceptible to erosion, takes on moisture, can fracture, crack and fall apart. Mudjacking was a fine solution when it was the only alternative to tearing your concrete out. But now with the advent of polymers, it’s becoming obsolete.
