what causes uneven floors in a home?
Concrete slabs are often poured on wet, weak, or poorly compacted soil. Over time, this will lead to settlement of the slab, causing uneven floors or cracking. Inside your home, your floor will pull away from walls and doorways, creating gaps at the seams.
This not only creates an uncomfortable home with tripping hazards, it also significantly impacts property value. When prospective buyers have to deal with foundation issues, it can make selling a home very challenging.
When To Repair Your Concrete Slab?
Uneven or Sloping Floors
Uneven or Sloping Floors
If your floor feels unlevel when you walk across it, the slab underneath may have settled. You might notice furniture leaning or gaps forming along baseboards. This often points to soil movement or voids beneath the concrete. Leveling the slab restores stability and helps prevent further shifting.
Cracks in Interior Concrete
Cracks in Interior Concrete
Cracks in your basement or garage floor are often a sign that part of the slab has dropped. When soil erodes or compacts unevenly, the concrete above it can split under stress. Small cracks can widen over time if the underlying issue is not corrected. Repairing the slab helps stop the movement that causes those cracks.
Sinking or Soft Spots Underfoot
Sinking or Soft Spots Underfoot
If parts of your floor feel lower or hollow, there may be empty spaces beneath the slab. These voids develop when supporting soil washes out or shrinks. As the slab loses support, it can settle or become unstable. Lifting it with PolyLevel® fills those gaps and restores solid support.
Tripping Hazards or Height Differences
Tripping Hazards or Height Differences
A noticeable height change between sections of interior concrete is more than cosmetic. It signals uneven settlement below the surface. Left alone, the separation can worsen and create safety concerns. Correcting the elevation protects both your floor and the people walking on it.
Water Issues and Soil Movement
Water Issues and Soil Movement
In areas with clay-rich soil, changes in moisture can cause expansion and shrinkage beneath your home. That movement affects the slab’s ability to stay level. Over time, repeated soil shifts lead to settling and cracking. Stabilizing the slab addresses the root problem before it spreads further.

The Best Solution For The Problem
PolyLevel® foam injection levels uneven interior concrete slabs without tearing it out. Expanding foam is placed beneath the slab to fill voids, lift the surface, and create lasting support.
PolyLevel® Foam Injection
PolyLevel® restores settled interior slabs using high-density expanding polyurethane foam. Small holes are drilled through the concrete, and the foam is injected beneath the surface. As it expands, it fills voids and carefully lifts the slab back into place, creating stable, long-term support.
NexusPro® Joint & Crack Sealing
NexusPro® is a silicone-based sealant designed to seal concrete joints and cracks. It stays flexible over time and holds up in changing temperatures. Unlike polyurethane products, it resists UV exposure to help prevent cracking and breakdown. It cures quickly, so your concrete is ready for use sooner.
SealantPro™ Concrete Protection
SealantPro® helps extend the life of concrete by protecting it from water and chemical absorption that can lead to pitting, flaking, and stains. It penetrates the surface and bonds within the concrete to create a lasting barrier. A temporary colorant shows where it has been applied. One professional application delivers long-term protection against moisture and surface damage.
CONCRETE SLAB LEVELING PROCESS
Thorough Interior Slab Inspection
We begin with a detailed inspection of your interior concrete slab. Our team evaluates uneven areas, cracks, and signs of settlement to determine where support has been lost. We identify voids beneath the slab and confirm the underlying cause of movement. This ensures the repair plan targets the real problem, not just the surface symptoms.
Precision Drilling
Small holes, typically less than one inch in diameter, are carefully drilled through the affected slab. These access points allow us to reach the empty spaces beneath the concrete. The placement is strategic to ensure even lift and full support. The holes are minimal and designed to preserve the appearance of your interior space.
PolyLevel® Foam Injection
High-density PolyLevel polyurethane foam is injected beneath the slab through the drilled holes. The material expands to fill voids caused by soil settlement or erosion. As it spreads, it begins stabilizing and supporting the slab from below. It reaches most of its strength within minutes.
Controlled Slab Lifting and Stabilization
As the foam expands, we closely monitor the slab’s movement. The lift is adjusted with precision to restore a level surface. This controlled approach ensures proper alignment without overcorrecting. Once stabilized, the slab is supported by lightweight, durable material that will not overburden weak soils.
Sealing and Clean Finish with NexusPro® or SealantPro™
After leveling is complete, the drilled holes are sealed to restore a clean appearance. This step helps protect the surface and maintain a finished look. The materials cure quickly, allowing the area to be used shortly after installation. Most homeowners can resume normal activity the same day.

How fast can I walk on it?
PolyLevel® reaches most of its strength within about 15 to 30 minutes after injection. In most cases, you can walk on the repaired surface shortly after the work is completed. This quick cure time minimizes downtime inside your home. You will not have to wait days for the slab to be usable again.
Is PolyLevel better than mudjacking?
PolyLevel® uses a lightweight, high-density polyurethane foam instead of a heavy cement slurry. The foam is waterproof and does not degrade over time, helping resist future erosion beneath the slab. Because it is lighter, it will not add extra stress to already weak soils. It also allows for more precise lifting and faster cure times.
During what seasonal conditions does it work?
PolyLevel® can be installed year-round. Unlike some traditional methods, it is not affected by cold temperatures in the same way. This allows interior slab leveling to be completed during different seasons without long delays. Your repair schedule is not limited to warm weather months.
Will the slab sink again?
PolyLevel® fills voids beneath the slab and helps compact the supporting soil. By restoring proper support, it reduces the risk of continued settlement. While no repair can control all future soil movement, this system is designed to create long-term stability. Addressing the underlying voids is key to preventing recurring sinking.
How disruptive is the process?
The process is minimally invasive and does not require removing the slab. Small holes are drilled, and the foam is injected beneath the surface. There is no heavy excavation or large equipment brought inside your home. Most projects are completed quickly with minimal cleanup.
