Correct Sunken Concrete Surfaces With Foam Injection

Concrete Lifting and Leveling in Milo for driveways, walkways, and floors that have dropped and created trip hazards or drainage problems

Statewide Foam and Coatings offers concrete lifting and leveling to residential homeowners, commercial property managers, and facility operators who need to fix uneven slabs without the time and cost of full replacement. When a section of driveway settles several inches below the garage floor, or a walkway develops a pronounced dip that collects water and ice, the problem is usually not the concrete itself but the soil beneath it that has compacted, washed away, or shifted due to poor drainage or freeze-thaw movement.

This service uses polyurethane foam injection to lift the sunken slab back to its original position and fill the voids that caused it to settle. The foam is pumped through small holes drilled into the surface, expands beneath the concrete, and hardens into a rigid support layer that will not compress or wash away. In Maine, where frost heave and seasonal groundwater fluctuations are common, this method stabilizes the subgrade and eliminates the conditions that led to settlement in the first place.

If you own property in Milo and need to level concrete surfaces that have dropped, reach out to discuss how foam lifting can restore safe, even surfaces without tearing out and replacing the slabs.

The crew drills penny-sized holes through the settled slab at intervals determined by the size and depth of the voids, inserts injection ports, and pumps high-density foam beneath the concrete. You watch the slab rise gradually as the foam expands, filling gaps and pushing the concrete upward until it aligns with adjacent sections. The foam cures within minutes, providing immediate load-bearing support for foot traffic, vehicle weight, or equipment loads.

After the work is complete, the surface is level, water drains away from the building instead of pooling in low spots, and the trip hazard at the step or joint is eliminated. Statewide Foam and Coatings monitors the lift with precision instruments to ensure the slab rises evenly without cracking or over-lifting, and the injection holes are patched with color-matched filler that blends with the surrounding concrete.

The process works on driveways, sidewalks, patios, garage floors, pool decks, and basement slabs where the concrete is intact but has settled due to subgrade issues. It does not repair slabs that are heavily cracked, broken into multiple pieces, or deteriorated to the point where the surface is spalling or crumbling. The crew evaluates each site to determine whether lifting will deliver lasting results or whether replacement is the better option.

Questions Homeowners and Property Owners Ask

People often want to know what causes concrete to sink and whether foam lifting will hold up over time.

What makes concrete slabs settle in the first place?

Soil beneath the slab compresses under load, water washes away fine particles through cracks or gaps, or the base was not compacted properly during construction, leaving voids that allow the concrete to drop.

How long does the lifting process take?

Most residential projects are completed in a few hours, and the treated area can carry normal foot or vehicle traffic within 15 to 30 minutes after foam injection.

Why is polyurethane foam better than mud jacking?

Foam weighs a fraction of what cementitious grout does, cures faster, and will not add load to already compromised soils, which makes it more reliable for long-term stability in areas with weak or shifting subgrades.

What will the surface look like after the work is done?

The injection holes are small and patched flush with the surrounding concrete, and the slab will be level with no visible signs of settlement other than the filled drill points.

When should you replace the concrete instead of lifting it?

If the slab is heavily cracked, broken into sections, or deteriorated beyond the point where it can safely carry loads, replacement is the more practical solution.
