Permanently Lifting and Leveling Sinking Concrete with PolyLevel Foam

The PolyLevel system provides a new, state-of-the-art solution to a very old problem: sinking or settling concrete. Virtually every type of concrete flatwork (slabs, sidewalks, driveways, runways, patios, and more) is susceptible to sinking if the supporting soil is loose, weak or prone to compression. Concrete will also sink when the supporting soil beneath it is washed away.

Traditionally, contractors had two main methods of dealing with sunken concrete: demolition followed by reconstruction or mud jacking to raise a sunken slab via hydraulic pressure. PolyLevel provides an alternative to these techniques, offering notable advantages, including speed, effectiveness and soil consolidation capability (meaning it addresses the cause of the problem, not just the symptoms).

PolyLevel was engineered to permanently raise and level sinking concrete slabs. As seen here, the polyurethane foam fills voids underneath the concrete to help it become level again.

Basic Technical Details About PolyLevel

  • The PolyLevel system utilizes an expanding, two-part, closed-cell polyurethane foam to raise sunken concrete. The system includes not only the two-part foam but also highly calibrated storage, temperature management and dispensing equipment typically housed in a customized box truck.
  • The two-part PolyLevel mixture is a modified geotechnical version of the spray polyurethane foam (SPF) systems used to insulate and seal residential and commercial buildings. In the PolyLevel system, the two parts are referred to as "Part A" and "Part B."
  • Part A is a petroleum-based isocyanate. Part B contains polyol resin, a surfactant, a blowing agent and a catalyst that causes the two liquid compounds to turn into expanding foam when they are mixed at the application nozzle.
  • The PolyLevel foam is injected beneath settled concrete through 5/8-inch-diameter holes drilled through the concrete at strategic locations, ideal for residential and commercial applications.

Why PolyLevel is Ideal for Slabjacking Applications

High strength-to-weight ratio

High strength-to-weight ratio

Unlike mudjacking techniques that pump mortar-based material beneath settled concrete, PolyLevel imposes very little additional weight on the soil. It's a much more effective slab-raising strategy in areas where soils are easily compressed or have poor load-bearing characteristics.

Superior lifting capability

Superior lifting capability

PolyLevel has almost unlimited lifting capability when applied by an experienced technician. Lifting force can approach 6000 lbs. per sq. ft. Settled factory floors and sections of airport runways have been successfully restored to level using PolyLevel.

Excellent dimensional stability

Excellent dimensional stability

PolyLevel foam hardens and cures to a strong, rigid foam material that will not absorb water or alter its dimensions over time. Once cured, the material is totally inert and does not leech harmful chemicals into the soil.

Fast set up and cure

Fast set up and cure

Following application beneath a settled slab or other concrete element, PolyLevel foam expands immediately to many times its liquid volume to create a powerful lifting force. In a matter of minutes, the foam begins to harden, typically reaching around 90% of its final strength and rigidity in under 20 minutes. These fast setup and cure characteristics minimize downtime, so that the concrete can become fully functional again almost immediately.

Soil strengthening capability

Soil strengthening capability

Once injected, PolyLevel foam does more than expand upward against the sunken concrete. It also moves downward, expanding into loose soil areas that can benefit from the foam's consolidating action. Other geotechnical applications of PolyLevel include soil stabilization, erosion control and preconstruction soil treatment to improve stability and load-bearing values.

PolyLevel Beats Other Concrete Repair Methods

PolyLevel is an innovative, long-lasting solution, unlike many other concrete leveling methods. The expanding, high-density polymer foam lifts interior and exterior slabs quickly and effectively while also addressing the soil issues that caused the settlement in the first place.
