Foam lifts the slab, not your budget

Polyjacking is our first choice for concrete leveling in Columbia, and for good reason. We drill a line of holes barely wider than a pencil, then inject a two-part polyurethane foam that expands under the slab. As it grows it fills every void and lifts the concrete back to level in controlled steps. The foam sets in minutes, so a foam-lifted driveway or garage floor is ready to use the same afternoon. Because foam concrete leveling is light and waterproof, it does not press down on the weak soil that let the slab sink in the first place, and it will never wash out in the rain.

Why homeowners pick foam

What polyurethane concrete lifting gives you

■

Pencil-sized holes

Foam ports are far smaller than the holes mudjacking needs, so there is less to patch and less to see afterward.

■

Cured in minutes

The foam reaches full strength almost immediately. Park on the driveway or walk the sidewalk the same day.

■

Light on weak soil

Foam adds almost no weight, so it will not overload the same soft ground that let the slab settle to begin with.

■

Waterproof and stable

Polyurethane does not absorb water or break down, so a foam lift holds up to Maryland rain and freeze-thaw.

■

Works in winter

Foam cures in colder weather than a cement slurry, so a trip hazard does not have to wait for spring.

■

Fills the voids too

The same foam seals the empty pockets under the slab, so water has nowhere to collect and wash the base out again.

Foam or mudjacking?

Polyjacking vs mudjacking, in plain terms

Both raise a sunken slab by pumping material into the gap underneath. The difference is what goes in. Mudjacking uses a heavy cement slurry through larger holes, and it can be the cheaper choice on big, thick slabs. Polyjacking uses expanding foam through small holes, cures far faster, and does not add weight to soft ground. For the aging residential driveways, walks, and garage floors we see across Columbia and Ellicott City, foam usually wins. On the phone or at your slab, we will tell you which method fits and quote both if it is a close call.

Polyjacking FAQs

Quick answers

Polyjacking, also called foam jacking or polyurethane concrete lifting, raises a sunken slab by injecting expanding foam underneath it. We drill pencil-sized holes, pump the two-part foam in, and it expands to fill the empty space and float the concrete back to level. The foam sets hard in a few minutes.

For most Columbia homes, yes. Foam weighs a fraction of a cement slurry, so it does not push down on soil that is already weak. The holes are smaller, it cures in minutes instead of a day, and it never washes out. Mudjacking still wins on cost for very large, heavy slabs, and we will say so if that is your situation.

Yes. Polyurethane foam cures at lower temperatures than a mudjacking slurry, so foam jobs keep going through the Maryland winter when mudjacking has to wait for warmer days. If your slab is a trip hazard now, we do not have to put it off until spring.

Barely. The ports are about the size of a dime and we patch them with a color-matched compound when we finish. From standing height on a driveway or walk, most people cannot pick out where they were.
