PolyLevel Injection

We Use PolyLevel® Injection Foam to Raise Settled Interior Slabs in Bangor, Portland, Rochester

PolyLevel® geotechnical capabilities:

  • Lift settled slabs and slab foundations
  • Lift and level sunken interior floors
  • Strengthen and stabilize loose soil

Concrete is a heavy material and so are the structures that concrete slabs and footings are expected to support. Sometimes, the combined weight of concrete and what it supports causes concrete settlement to occur. The soil beneath the concrete compresses and can cause major problems, including tripping hazards.

PolyLevel® is designed specifically to repair this type of problem in Portsmouth, Lewiston, Waterville, Dover, Auburn, Biddeford, South Portland and other nearby areas.

Interior Concrete Leveling in Greater Portland

We can help you eliminate tripping hazards with our quick and reliable interior slab leveling solution.

  • Strong but light. PolyLevel® weighs only about 4lbs. per cubic ft., compared to 120lbs. per cubic ft. for standard fill material. PolyLevel® ’s lightweight makes it useful where denser fill material might impose an undesirable load on weak soils. Despite its lightweight, PolyLevel® can support substantial loads; it typically provides greater lifting power.
  • Waterproof. 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 leach harmful chemicals into the soil.
  • Quick curing. Downtime is minimized with PolyLevel® concrete repair. Full loading of the foundation or other structural elements can usually happen about 15 minutes after the material is injected.
  • Adjustable. 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 and temperature and weather conditions. Special formulations are possible for applications where water must be displaced.
  • Noninvasive. 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.

Polymer injection solves soil settlement and stabilization problems

In the past, contractors often raised settled concrete by pumping a liquid mortar beneath the settled section (called mud jacking). But this pumping process is hard to control, and the added mass of the mortar puts even more weight on the soil.

Fortunately, foundation and concrete repair specialists now have 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 and strengthen soil that has poor load-bearing qualities.

The polymer consists of two separate liquids that are combined 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 those at TC Hafford Basement Systems, 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 slabs to be put back into service right away. The speed of polymer injection repairs is another huge advantage over mortar pumping.
