Mudjacking in Columbia, MD

Slab jacking with a cement slurry. The slurry costs less than foam, so on a big driveway or a wide walk it's usually the cheapest way to bring sunken concrete back up.

The proven, low-cost lift

Slab jacking that has worked for decades

Mudjacking is the method that was lifting sunken concrete long before foam showed up, and there are still jobs where we'd rather use it. The way it works, we drill through the low slab and pump a slurry of cement and soil into the space underneath, and the slab comes up with it until everything sits level again. Because the slurry costs so little compared to foam, a big thick pour like a full driveway or a wide walk can come in noticeably cheaper per square foot with mudjacking than it would with polyurethane. So if the price matters more than the cleanup and your slab is heavy enough to suit the method, cement raising is usually where we land, and when it's the other way around and foam earns its higher price on your slab, we'll just say so.

Good jobs for slab jacking

■

Large driveways

Wide, heavy driveway slabs where the lower material cost of a slurry adds up to real savings.

■

Thick, heavy slabs

Sidewalks and pads built thick enough that the weight of the slurry is not a concern for the soil below.

■

Budget-first jobs

When the goal is to lift the slab for the lowest price and the surface is not high-visibility, slab jacking delivers.

■

Filling large voids

Big empty pockets under a slab take a lot of material, and slurry is an economical way to fill them.

■

Shed and utility pads

Out-of-sight slabs where a slightly larger patched hole does not matter and cost is what counts.

■

How the lift happens

Drill, pump, raise, patch

There isn't much mystery to the process. We drill a pattern of holes across the sunken section, set up the pump, and start pushing slurry underneath, and as the material fills the void the slab creeps upward a little at a time while we watch it against the concrete around it. Once everything sits flush we plug the holes and clean up after ourselves. Most residential mudjacking runs a few hours start to finish, and while you can walk the slab pretty quickly, we'll tell you before we go exactly how long to keep the cars off it.

Mudjacking FAQs

Quick answers

Mudjacking, slab jacking, and cement raising are all the same repair under different names, a cement-and-soil slurry pumped into the gap under a sunken slab until the void fills and the concrete comes back up to level. It's been the standard concrete lifting method for decades because it works, especially on the large heavy slabs that would take a lot of foam to move.

Depends on the slab, and on what's under it. Mudjacking wins on price per square foot when the concrete is big and thick, while foam makes more sense on weak or wet ground because it's lighter, cures faster, and needs smaller holes. Once we've seen your slab we'll tell you which of the two is the better value for the job you actually have.

The slab will hold weight right away, but the slurry under it keeps curing for a while after we leave, so we ask you to keep vehicles off a mudjacked driveway for about 24 hours to be safe. Foot traffic is a different story and is usually fine much sooner, and before we pack up you'll know the exact window for your particular job.

They're bigger than foam ports, and that's worth knowing before you choose. A mudjacking hole runs about the size of a golf ball because the slurry needs room to flow, where a foam port is closer to a dime, and even with the color-matched patch we finish with, the larger patches are easier to pick out on a surface you look at every day.
