PolyLevel for concrete repair

Concrete is a heavy material and so are the vehicles, machinery and structures that concrete slabs and footings support.

Sometimes, the combined weight of concrete and what it supports causes concrete settlement. The soil beneath the concrete compresses and when it does, it can cause major problems.

We offer a permanent, affordable solution to these concrete problems: PolyLevel.

What is PolyLevel for concrete?

PolyLevel® is a state-of-the-art approach to repairing sinking concrete using a polymer injection.

In the past, contractors often raised settled concrete by pumping a liquid mortar beneath the settled section (called mudjacking).

But this pumping process is hard to control, and the added mass of the mortar puts even more weight on the soil.

Fortunately, LRE Foundation Repair offers a new technique that's more effective at raising settled concrete. Polymer injection harnesses the expansive force of a structural-grade geopolymer to:

  • Provide fast concrete leveling
  • Fill voids in soil
  • Strengthen soil that has poor load-bearing qualities

Foaming polymer injections for concrete leveling

PolyLevel is a polymer injection consisting of two separate liquids that combine right at the injection nozzle to trigger a chemical reaction that turns the blended ingredients into expanding, high-density foam.

The foam flows into voids and between loose soil particles, expanding to about 15 times its initial volume. This expansive action effectively lifts settled concrete.

An experienced technician, like our team members at LRE Foundation Repair, can control the application to create just the right amount of raising pressure.

The polymer begins to harden quickly after doing its raising work.

Within just 30 minutes, it reaches 90% of its final strength, enabling damaged concrete roads and slabs to be put back into service right away.

The speed of polymer injection repairs is another huge advantage over mortar pumping.

In addition to lifting and realigning settled and/or shifted concrete, polymer injection can be done prior to construction to improve soil stability and strength. Injections as deep as 20ft.-30ft. are possible.

PolyLevel® advantages

In all of our years of experience, we’ve been pleased to see this product change how we fix and level concrete. PolyLevel is a modern technology that removes many of the hassles and disadvantages to mudjacking and concrete replacement.

Strong but light

PolyLevel® weighs only about 4lbs. per cubic ft. (This is very light compared to 120lbs. per cubic ft. for standard fill material used in mudjacking!) PolyLevel's lightweightedness makes it useful where denser fill material might impose an undesirable load on weak soils.

Despite its light weight, PolyLevel® can support substantial loads; it typically provides greater lifting power than mudjacking.


Once cured, PolyLevel® will not wash away. PolyLevel® ’s waterproofing properties can be beneficial in certain applications.

Stable and inert.

PolyLevel® does not react with soil or moisture; it will not leak harmful chemicals into the soil. It is quick curing and down time is minimized with PolyLevel® concrete repair. Full loading of the foundation, roadway or other structural element can usually happen about 15 minutes after the material is injected.


Adjusting the density and expansive force of the 2-part foam affords a wide range of geotechnical uses. Lifting force can be adjusted by fine-tuning the chemical reaction that causes the foam to expand.

An experienced applicator can factor not only the weight of the structural element, but also soil characteristics, temperature and weather conditions. Special formulations are possible for applications where water must be displaced.


PolyLevel® injection equipment isn’t bulky, enabling applicators to access confined areas. When properly injected, PolyLevel® is not as messy or disruptive as other slab and foundation-lifting techniques.

What can PolyLevel® do?

  • Lift settled slabs and slab foundations
  • Lift and level sunken sidewalks
  • Strengthen and stabilize loose soil
  • Fill voids in the soil
  • Lift, level and stabilize roadways and airport runways
  • Repair and stabilize rail beds weakened by soil washouts
  • Treat soil to improve load-bearing characteristics in preconstruction applications

Commercial concrete problems

Commercially, concrete roadways can become dangerous or unusable. This often results in sections of runways and parking lots closing down. In the example of trains, train service can be interrupted because of erosion and settlement beneath the track bed.

Residential concrete problems

Concrete problems are also common around the house. Uneven sidewalks, pool decks and concrete steps can cause tripping. Sunken driveway slabs can make parking your car in the garage quite a challenge.
