What is concrete leveling?

Concrete leveling is a repair method that lifts and re-supports sunken slabs like driveways, sidewalks, patios, and garage floors. Instead of removing the concrete, small holes are drilled and material is injected under the slab to raise it back into position and fill voids under it.

What causes concrete to sink or settle?

Concrete usually sinks when the soil under it loses support. Common causes include erosion from water, poor compaction, plumbing leaks, downspouts dumping water near the slab, and soil shrinkage over time. When the base weakens, the slab drops and can crack or tilt.

Is concrete leveling cheaper than replacing concrete?

In many cases, yes. Leveling typically costs less than tearing out and replacing a slab because there is no demolition, haul-away, or new concrete pour. It also reduces disruption to your home or business.

How long does concrete leveling take?

Most concrete leveling jobs are completed in a few hours, depending on how many slabs are affected and how far they need to be lifted. Larger commercial areas may take longer, but it is still usually much faster than replacement.

Can I use my driveway or sidewalk the same day?

Often, yes. Many projects are ready to use the same day after the slab is lifted and the work area is cleaned up. Your technician will confirm the best timing based on the specific repair and conditions.

Will concrete leveling fix trip hazards?

Yes. Lifting an uneven sidewalk or walkway can remove the height difference that causes trips. It also helps restore safer footing and can reduce liability risks for homeowners and property managers.

Does concrete leveling stop water from pooling?

It can. When a slab settles, it often creates low spots that collect water. Leveling can restore the proper slope so water drains away instead of pooling near your home, garage, or entry points.

Will leveling prevent future settling?

Leveling restores support under the slab, but long-term results depend on fixing the reason the soil failed. Improving drainage, extending downspouts, and addressing leaks are important. If voids are present, void filling and soil stabilization can help repairs last longer.

How big are the drill holes and will they be visible?

Concrete leveling uses small drill holes. After lifting, the holes are patched. You may still be able to find them if you look closely, but they are much less noticeable than saw cuts, tear-out lines, or replacement seams.

Can you level cracked concrete or does it need to be replaced?

Many cracked slabs can still be lifted as long as the concrete pieces are stable and the slab is not severely broken apart. If the concrete is fragmented into many loose sections, replacement may be the better option.

What is the difference between polyurethane foam leveling and mudjacking?

Both methods lift concrete, but they use different materials. Polyurethane foam is lightweight and expands to fill voids, while mudjacking uses a heavier cement-based slurry. The best option depends on the slab, the soil conditions, and the goals of the repair.

Do you level commercial concrete like parking lots and warehouse floors?

Yes, concrete leveling is commonly used for commercial areas like parking lots, loading zones, interior floors, sidewalks, and entryways. It helps reduce downtime and avoids closing areas for long replacement projects.

When should I replace concrete instead of leveling it?

Replacement may be needed when the slab is severely broken, has major heaving, or the concrete is too deteriorated to lift safely. A quick inspection can usually determine whether leveling is a good fit.

How do I know if I have voids under my concrete?

Common signs include hollow sounds when tapped, sinking corners, cracks that keep reopening, and areas that wash out after heavy rain. Voids often form from erosion, and filling them helps prevent further settlement.

Concrete rests on subgrade, which is a fancy term for the earth below. When the subgrade begins to weaken and settle, the concrete loses its support. This can be caused by a variety of factors…weather, rain, leaks, excess weight to name a few. While the root causes may vary, the end result is always the same. Structural damage.

Over time, often in months, concrete begin to stress, then crack and, eventually, break apart and sink. This leads to trip hazards, unsightly appearance and a reduction in property values. This damage is structural – not cosmetic. Neither patching nor a new surface will solve the problem.

At Poly Lift USA we offer customers an environmentally safe, affordable, long-term resolution.

Our Foamjection technology has enabled thousands of property owners in Florida, Georgia and Texas to repair their damaged driveway and save thousands in replacement costs. Our typical repair is well under 50% less than cost of replacement.

Here’s how Foamjection technology works:

Penny size holes are drilled through the damaged slab at 5-foot intervals.
Specially formulated polyurethane foam is pumped through the slab reaching the subgrade underneath.
The liquid foam fills voids and expands rapidly to compact the earth beneath the slab.
As the foam hardens it locks the slab in place. We call this stabilization.
When lift is required, additional foam is pumped using carefully calibrated pressure gauges until the slab is raised to the desired height.
Drill holes are filled with sanded concrete.

How It Works

Foamjection Technology is designed to compact subgrade that is weak or sinking,
stabilize the concrete slab above and, if necessary, lift the slab to eliminate unlevel surfaces and trip hazards.

Step 1

Penny size holes are drilled through the slab where the damage exists. About five feet apart.

Step 2

Ports are installed and hot, liquid Polyurethane foam is injected under pressure. The foam expands to compact the subgrade and stabilize the slab. Pressure gauges tell the installer when the subgrade is fully compacted, and the slab is stabilized.

Step 3

If lift is desired, additional foam is injected very slowly to raise the slab as close as possible to its original position.

Step 4

The injection sites are filled and leveled using sanded concrete. The work area is cleaned.

Most projects are completed in less than a day. The slab is ready for use within one hour of completion.
All Poly Lift teams are full-time employees and each Crew Chief has completed well over 1,000 projects.
