How PolyLevel® Works

The causes of concrete settlement and sinking are the same whether it's a driveway, walkway, patio, garage floor, or pool deck. As soil underneath a concrete slab shrinks, settles or washes away, this leaves empty space, or voids, beneath the slab. With the soil no longer supporting the slab, the concrete will sink, creating an uneven surface.

PolyLevel uses a high-density polyurethane foam to fill voids and stabilize and lift sinking concrete slabs. The expanding properties of the two-part urethane formula allows for accurate leveling of the slab. The result is a waterproof repair that's much more permanent than mudjacking and other common concrete repair methods.

PolyLevel step 1: drilling injection holes


Small 5/8” holes are strategically drilled in the slab.

PolyLevel step 2: installing injection ports


Injection ports are installed.

PolyLevel step 3: injecting polyurethane foam


Polyurethane foam is injected beneath the concrete to fill voids and raise the slab.

PolyLevel step 4: sealing holes and control joints


Holes and control joints are sealed.

  • PolyLevel® Concrete Leveling - Woodside, Ca
    PolyLevel® Concrete Leveling - Woodside, Ca

    A beautiful hillside home in Woodside California was experiencing a fairly significant amount of movement where their 8 inch concrete slab driveway met the garage.  The sinking was getting so significant it became difficult to move their vehicles in and out of the garage. 


    We are so happy they called us, because we had the solution.  Instead of tearing out their otherwise pristine concrete, the Foundation Repair of Ca concrete repair team used our PolyLevel® foam injection system to raise the slab back to its original height. 


    This permanent solution was able to be completed in just a couple of hours at a fraction of the cost of removal and replacement.

  • Lifting a Residential Driveway/Parking Area in Tiburon, CA
    Lifting a Residential Driveway/Parking Area in Tiburon, CA

    This homeowner in Tiburon had a driveway/parking area that sank six inches due to the shifting soil beneath it. This movement caused the flow of water to be disrupted and multiple puddles would remain long after it rained.

    After contacting Foundation Repair of California, one of our crews used a PolyLevel injection to lift the slab six inches and back to its original position. The PolyLevel process uses a 2-part polyurethane foam to quickly and efficiently raise the concrete slabs that are used in patios, driveways, and much more.

    This homeowner is now happy with their driveway that not only looks great again, but correctly directs any water to their drainage system! Contact us today to schedule your free estimate.


  • A Cracked Patio
    A Cracked Patio

    This patio was a concrete slab it had a crack that practically cut it in half. One half of the slab was sinking too. So the homeowner contacted us, Foundation Repair of CA. Our solution was our PolyLevel Foam; this high density foam lifted the lower half to meet the stable half of the slab.

  • Sunken Pool in Clovis, CA
    Sunken Pool in Clovis, CA

    This homeowner was all geared up and ready for the summer, when he realized that a slab in his pool deck was sinking, causing not only a bad tripping hazard, but also an ugly crack in the middle of the slab. Knowing that this was unsafe for his kids, and unseemly for his preference, he called Foundation Repair and our Concrete Repair Specialist Jim Palamides came out to evaluate the problem. Jim was able to find the perfect solution to solve this issue, and thanks to a PolyLevel Foam injection, and Nexus Pro sealant, his entire pool deck is completely level and there are no more hideous cracks. Now, this homeowner can go back to what's important: Swimming and having fun in the summer sun!

Traditional Concrete Lifting vs PolyLevel®

Before PolyLevel, there were two basic options for lifting and leveling concrete: mudjacking and slab replacement. Both approaches have limitations and disadvantages. PolyLevel offers many advantages over traditional concrete leveling methods:


Foam Injection
Mudjacking or Slabjacking
Cure Time 15 minutes 24 hours or more
Material Weight 2 lbs per cubic foot 100 lbs per cubic foot
Hole Size 5/8" (size of a penny) 1" (size of a quarter)
Waterproof Yes No

Concrete Replacement

Replacing a concrete slab is both expensive and disruptive. Concrete slabs can take days - or even weeks - to cure. Pouring new concrete over bad soil often delays future problems and leaves unsightly patchwork. PolyLevel material is lightweight, so it won't add weight to weak soil. Best of all, PolyLevel allows for use of concrete within hours, not weeks.

If your concrete is structurally-sound, why replace it? Replacing the concrete won't fix the soil problem that's causing the settlement. Concrete leveling is the answer.
