Professional Concrete Lifting Services by American Standard Foundation Repair

Uneven or sinking concrete is more than just a cosmetic issue, it can create trip hazards, drainage problems, and long-term structural concerns for your home or business. At American Standard Foundation Repair, we provide advanced polyurethane concrete lifting services in Knoxville, TN and throughout the greater East Tennessee area to restore safety, stability, and appearance without the cost of full concrete replacement.

Common Concrete Problems in Tennessee

We frequently repair sinking driveways, uneven sidewalks and walkways, settled patios and porches, interior slab floor settlement, garage floor sinking, pool deck leveling, commercial concrete surfaces, and raised edges that create trip hazards.

In many cases, these issues are not isolated surface problems but signs of underlying soil movement. Addressing the settlement early can help prevent more extensive damage over time.

What Is Polyurethane Concrete Lifting?

Polyurethane concrete lifting, also known as polyjacking or foam jacking, is a modern repair method that uses high-density expanding foam to raise and stabilize sunken concrete slabs.

Instead of tearing out and replacing concrete, we carefully lift it back into place by filling the voids underneath with structural foam. This process restores the slab to its proper elevation while strengthening the soil support below it.

If you are noticing sinking, cracking, or uneven concrete, it is important to address the issue before it worsens. Early repair can help prevent additional settlement and reduce long-term repair costs.

How Does Polyurethane Foam Lifting Work?

Polyurethane foam lifting is a minimally invasive solution for uneven or sunken concrete. 

  • Inspection & evaluation: We conduct a detailed assessment of the affected concrete to determine the cause and extent of settlement, including soil erosion, voids, drainage issues, and structural movement.
  • Drilling injection points: Small, strategically placed holes (about the size of a penny) are drilled into the slab, creating access points for the foam without damaging the surrounding surface.
  • Foam injection: A specialized two-component polyurethane material is injected beneath the slab. As it expands, it fills voids, compacts loose soil, and gently raises the concrete toward its original position.
  • Controlled lifting: The process is monitored in real time for precise leveling and stabilization as the slab rises.
  • Curing & reinforcement: Once raised, the foam cures into a strong, lightweight, water-resistant layer that reinforces the soil and helps prevent future settlement.
  • Finishing touches: Injection points are sealed and the surface is cleaned, leaving a smooth, level area that’s typically ready for immediate use.

Our goal is to restore your concrete quickly and effectively, with minimal mess and long-lasting results.

Concrete can be lifted to its original place.
