House Slab Leveling & Foundation Slab Lifting

Most residential concrete leveling jobs land between $900 and $2,900, depending on how much slab has to be lifted and how far it has settled. A small sidewalk section or a single sunken driveway panel sits at the low end. A full garage floor or a large pool deck sits at the high end. It is almost always a fraction of tear-out and replacement, which typically runs three to five times more for the same area. We quote the exact number on site for free before any work starts.

Yes, substantially. Replacement means demolition, hauling away the old slab, new forms, new concrete, and a week of curing before you can use it. Leveling reuses the slab you already have, finishes in a few hours, and you can drive on it the same day. Replacement only makes sense when the concrete itself has failed structurally rather than simply settled.

The foam itself does not break down, wash out, or lose volume. It is a closed-cell structural polyurethane that stays inert in the ground indefinitely. What matters is that we fill the voids and compact the loose soil that caused the settlement in the first place, which is why properly injected slabs generally stay put for decades. Ask about the written warranty when we quote your job.

For nearly every residential job, yes, and the mixture is the reason. Polyurethane is two liquids, resin and iso, that have to meet at an exact 1:1 ratio, and the rig meters that automatically on every injection. Mudjacking slurry is dirt and concrete mixed at whatever ratio that crew happens to use, so two mudjacking contractors can pump genuinely different materials under two identical driveways. Foam also uses 5/8 inch holes instead of two-inch holes, is ready to use immediately instead of in days, and is closed-cell and waterproof so it will not wash out. Mudjacking also cannot lift a house slab.

A typical residential job is about an hour on site, and the concrete is ready to use as soon as we pack up. The foam reaches most of its final strength within roughly fifteen minutes of injection, which is why you can park on a driveway the same visit. Mudjacking usually needs 24 to 72 hours before it will carry weight, and a full replacement needs about a week of curing.

Replacement has one genuine advantage: the concrete looks brand new, which lifting cannot do. What it does not do is fix the ground. A slab sinks because the soil under it consolidated, washed out, or was never compacted properly, and pouring fresh concrete onto that same soil gives you a new slab sitting on the identical problem. Lifting fills the voids and compacts the subgrade, so it treats the cause. Replacement also costs the most and takes about a week of curing, where lifting is usually about an hour and usable immediately. If your concrete is badly broken or stained rather than simply settled, replacement may genuinely be the right call and we will tell you so.
