Frequently Asked Questions

Why does concrete sink?

One of the most common reasons that concrete will slip or move is due to an unstable foundation. Unsupported spaces under the ground may crumble or shift over time – which can cause the concrete above to crack and fall.

Another issue that will lead to concrete slippage is pressure from gravity, foot traffic, and constant weights. Although concrete is very strong, its compression strength decreases as time goes on. Most commercial-grade concrete’s rating is measured over the course of just 28 days. Repeated pressure will slowly wear away layers of the concrete, decreasing its strength.

Natural occurrences can cause cement slabs to shift, such as temperature changes, plate shifts, or even tree roots. You will see this quite often on sidewalks or cement driveways. Some slabs will be several inches higher than others or tilted at odd angles.

How does polyurethane foam lifting work?

Polyurethane concrete lifting foam (also called PolyLift or Polyjacking) is a strong chemical solution that creates a high-pressure foam strong enough to push concrete back into place. To insert the foam into the correct areas, a few holes need to be drilled into the concrete. 

Next, technicians will insert concrete lifting foam pumps into these holes. Polymer liquid is used inside the pumps to create polyurethane lifting foam which is funneled under the base of the concrete.

This creates enough pressure to lift the slabs back into place. The pumps are then removed and the small holes are re-filled with grout or concrete. All in all, this process takes less than an hour and the concrete can be used again as soon as the grout is dried.

 

 

Is the Polyurethane foam environmentally friendly?

Yes, the Polyurethane foam used by Advanced Poly Solutions is environmentally friendly and designed to have minimal ecological impact.

What can concrete lifting be used for?

There is a wide variety of applications suitable for poly foam lifting ranging from various sizes, the most common are.

  • Sidewalks
  • Driveways
  • Cement stairs
  • Patios
  • Concrete support beams
  • Pool decks
  • Garage floors

This is only a small list of possible applications with the power of foam lifting. Call us today Before going through the hassle of calling the concrete truck.

How long does it last?

Since this type of foam is made from synthetic materials, it will not break down or wear away. So, in most cases, the use of poly foam lifting is a permanent solution, creating a stronger foundation for the concrete than the natural dirt itself.

How long does it take to lift concrete?

The chemical reaction of the foam starts as soon as the product is injected under the surface of the concrete, And is fully cured withen minutes. This means most jobs can be completed in just one day from start to finish and you never have to sit and watch new concrete dry. Even driveways can be driven on immediately after the repair is complete.

How much does it cost?

Polyurethane lifting foam is an incredibly affordable solution. It will generally amount to less than half the cost of how much it would be to replace the broken concrete. Call us today for a FREE estimate on getting your concrete back to its original beauty.
