Concrete Slab Lifting & Mudjacking in Fort Worth, TX

Not every settled slab problem is a structural foundation problem. Driveways, sidewalks, garage floor slabs, and patios are poured separately from the home's structural foundation, and they settle on their own as the same expansive clay soil underneath shifts with the seasons — often years before or completely independent of any foundation movement inside the house.

We use two lifting methods depending on the slab and the situation. Traditional mudjacking pumps a cement-and-soil slurry underneath the settled slab, filling voids and raising it back toward grade; it's a proven approach but the slurry adds real weight and takes time to fully cure. Polyurethane foam injection uses a lightweight expanding foam that cures in about 15 minutes and adds far less load to the soil below, which makes it a better fit for softer or already-saturated ground. We recommend based on the slab, the soil, and what's causing the settlement, not a single default method.

A sunken walkway or driveway apron next to the house isn't just a trip hazard — it can also direct rainwater back toward the foundation instead of away from it, turning a cosmetic flatwork problem into a contributor to the kind of uneven moisture exposure that drives structural settlement. When we see that during an inspection, we flag it alongside our drainage and French drain recommendations rather than treating the two as unrelated.

Mudjacking and foam lifting are not a substitute for structural pier work. If elevation surveys show the home's actual foundation has settled, that calls for piers, not slab lifting under the flatwork around it — we're upfront about which situation you're actually looking at before recommending either.

Mudjacking vs. Polyurethane Foam

Mudjacking is the traditional method — a cement, soil, and water slurry pumped beneath the slab through small drilled holes — and it remains a solid, lower-cost option for larger slabs. Polyurethane foam cures almost immediately, weighs a fraction of a mudjacking slurry, and works well for slabs where added weight could contribute to future settling. We walk you through the tradeoff for your specific slab rather than defaulting to one method for every job.

When Sunken Concrete Signals a Bigger Drainage Problem

A driveway or walkway that's settled toward the house, rather than away from it, is often redirecting water into the same zone that puts stress on the foundation. We check the slope and drainage pattern around any sunken flatwork we're asked to lift, since fixing the concrete without addressing where the water goes afterward is a partial fix.

What We Won't Lift With Mudjacking

Mudjacking and foam injection raise non-structural flatwork — driveways, sidewalks, patios, garage floor slabs not tied into the home's structural footing. A home's actual settled foundation needs piers driven or screwed to stable bearing soil, not slurry or foam injected underneath it. We tell you plainly which category your project falls into before quoting either service.

How the Lifting Process Works

We start by drilling a series of small holes — typically around an inch or so in diameter — through the settled slab at points calculated to distribute the lifting material evenly underneath it. Mudjacking pumps the slurry mixture through these holes under pressure, filling voids and gradually raising the slab as material builds up beneath it; polyurethane foam is injected through smaller holes and expands within seconds, lifting the slab as it cures. Either way, we monitor the slab's elevation continuously during injection rather than pumping a set volume and hoping it lands right, stopping once the target elevation is reached. The drilled holes are patched afterward, and foam-lifted slabs are typically ready for light use within an hour, while mudjacked slabs need a longer cure period before heavier use like driving a car onto them.

Signs Your Concrete Has Settled

A visible gap or step where a driveway or walkway meets the garage floor or house foundation, water pooling on the slab instead of running off, and a noticeable slope toward the house rather than away from it are the clearest signs. Cracking at the edges of a settled slab, especially where it's pulled away from an adjoining structure, often accompanies the settlement itself. Homeowners sometimes wait years on a sunken driveway apron simply because it isn't a safety issue yet, not realizing it may already be redirecting water toward the foundation.

Warranty on Lifted Flatwork

Slab lifting work comes with a written warranty against the treated slab settling again from the same cause within the warranty period, and we're insured for the work performed. Because flatwork settlement and foundation settlement have different causes and different repair approaches, we document which category your project falls under at the time of the estimate, so the warranty terms match the actual service performed rather than creating confusion between flatwork lifting and structural pier warranties.

How Long the Results Last

Polyurethane foam and mudjacking slurry don't wear out or degrade the way some homeowners assume — once cured, both fill the void beneath the slab permanently, and the slab typically stays lifted unless the same underlying soil conditions that caused the original settlement recur and cause new movement. That's why we address drainage alongside any flatwork lift where water was contributing to the original settlement, since fixing the void without addressing continued water exposure can mean revisiting the same slab again in a few years. For flatwork sitting on soil we've already treated and drained properly, most lifts hold up well for many years without needing to be redone.

Concrete Slab Lifting & Mudjacking FAQs

What's the difference between mudjacking and polyurethane foam lifting?

Mudjacking pumps a cement-and-soil slurry beneath the slab and has a longer cure time; polyurethane foam expands and cures in about 15 minutes and adds much less weight to the soil underneath. We recommend based on the slab's condition and the soil it's sitting on.

Can you lift my garage floor without touching the home's foundation piers?

Yes, as long as the garage floor slab isn't structurally tied into the home's foundation system, we can raise it independently with mudjacking or foam injection.

Will a sunken driveway or sidewalk get worse if I leave it alone?

Usually, yes. Beyond becoming a bigger trip hazard, a slab that's settled toward the house can direct rainwater into the foundation zone instead of away from it, which can contribute to the uneven moisture exposure that drives structural settlement over time.
