Mudjacking in Richardson, TX
On a 1970s Richardson driveway, the cracks usually appear at the second expansion joint from the garage — that's where Houston Black clay's seasonal cycle has been pulling the slab edge down for forty-plus years. Mudjacking is the method that was on the truck when most of these slabs were poured, and on a meaningful share of them it's still the right call to bring them back to grade.

When mudjacking is the right call in Richardson
Richardson's housing stock is the oldest in our service area — median home built in 1974, with whole subdivisions in Richardson Heights and Canyon Creek that are now five decades into life on Houston Black. That clay has a 17% linear extensibility at the seed location, the highest of any city we work in. After fifty years of wet-dry cycling, the typical original-pour driveway, sidewalk, or back patio has voids underneath that are large enough to favor cement slurry over polyurethane on a per-cubic-foot basis.
Slurry — portland cement, sand, water, and sometimes a small fly-ash fraction — fills volume cheaply, sets hard, and bears weight indefinitely once cured. On the heavier flatwork that Richardson contractors poured in the 1960s and 1970s, the substantial cured fill underneath is exactly what you want supporting it. Mudjacking is also the established method on most municipal sidewalk specs and on detached garage and outbuilding slabs that see heavier point loads.
For the deeper how-it-works on the method itself — port spacing, pump pressure, cure timing — see our mudjacking guide. On this page we're focused on whether it's the right call here, and what it tends to look like on a Richardson lot.
When polyjacking is a better fit
Mudjacking covers most of what we lift in Richardson, but it isn't always the right answer. Polyurethane foam earns its premium in a few specific scenarios that come up on Richardson lots.
If your slab sits tight against the home's foundation and is settling toward the house — the side that's pulled away from the foundation line, with hairline gaps growing along the cold joint — the added weight of slurry fill underneath can in some cases compound the soil-loading problem. Polyjacking is usually the safer choice in that geometry.
If access to the slab is genuinely tight — a back patio reachable only through a narrow side gate with no truck-line route — the cost equation can tilt toward foam, which works from a smaller portable rig. Some Canyon Creek lots up north of Campbell Road have rolling terrain and limited equipment access; we'll tell you on the walk-through if that's the case.
And if the slab needs to be back in service within hours rather than a day or two, slurry cure times can't be rushed. Foam exists in part because that scenario was common enough to drive an industry shift. See our polyjacking guide if you want the comparison in detail.
What mudjacking costs in Richardson
Industry-typical residential mudjacking projects run $400 to $2,500 depending on slab area, lift height, void volume, and access. A single sunken driveway apron might come in near $400 to $700; a full one-car driveway lift typically sits in the $1,000 to $1,800 range; a multi-section back patio plus walkway can approach $2,500.
The cost-to-protect math in Richardson leans hard toward lifting. With ZIP 75080 owner-occupancy at 53.5%, half the housing here is rental — and landlords run the numbers more aggressively than owner-occupants. A $1,400 lift on a 50-year-old driveway beats a $9,000 driveway replacement that the next dry summer would set up to need anyway.

How Richardson slabs typically present
Calls in Richardson cluster around a recognizable set of scenarios that line up with the housing-stock age and decades of clay cycling.
Driveway aprons that have dropped at the second expansion joint from the garage. This is the single most common Richardson call. The garage slab is part of the foundation; the driveway is on grade; fifty years of Houston Black underneath has pulled the apron down a half-inch to two inches. A Richardson Heights driveway poured in 1955 has had seventy years of clay working on it.
Patios poured in the 1980s on uncompacted backyard fill. A meaningful share of Richardson back patios were homeowner-poured or small-contractor pours from that era, often laid directly over the original lot grade with light subbase prep. They've settled along the long edge that gets the most rain runoff, and they're usually mudjacking candidates because the void underneath is now substantial.
Sidewalks heaving over old plumbing penetrations. On older lots, the front walk often crosses a sewer or water-line cut that was backfilled in the 1960s or 1970s. The disturbed soil never fully consolidated, and decades of cycling have magnified the differential. We coordinate with the relevant utility before we lift around their penetration.
Detached garage slabs with point-load drops. Older Richardson properties tend to have detached garages and workshops poured to a heavier spec than modern attached-garage slabs. Mudjacking is the natural fit there — the slurry fill carries the heavier point loads of vehicles and equipment better than foam does.
Your Richardson mudjacking FAQ
Is mudjacking still relevant for newer Richardson homes? For most post-2000 Richardson builds, polyjacking is usually the better default — lighter, faster cure, less hydrostatic load on swelling clay. Mudjacking still earns its keep on heavier or larger slabs from the older housing stock, which is most of what's in 75080.
How long does a mudjacking lift hold on Houston Black clay? A correctly executed lift on stable subgrade typically holds 8-10 years or more. The lift itself is durable; the variable is whether the soil underneath continues to move. Twenty-five wet-dry cycles is a lot of accumulated motion, and we tell homeowners up front that the clay isn't done.
Will mudjacking damage my older slab? A controlled lift puts very little stress on the slab. The risk is overshoot — too much pressure or too much material at one port — and that's an experience problem, not a method problem. On an older Richardson slab with surface cracks, we'll often pre-stitch any cracks before the lift so the pressure doesn't propagate them.
Can mudjacking fix the slab next to my pool? Often yes, if the slab is sound and the void is large enough to favor slurry over foam. Pool-deck work has its own considerations though — see our pool deck leveling guide for the full conversation.
My driveway runs along an old tree root. Does that change anything? Yes. Mature trees in Richardson Heights and Canyon Creek were saplings when the original drives were poured; the roots are now in the slab. We assess whether the root is the cause of settlement (it usually isn't, on Houston Black) and whether root pruning belongs in the scope before the lift.
Do you guarantee the lift? We warranty the lift itself. We don't warranty the soil — if a plumbing leak or a long drought-cycle disturbs the subgrade later, that's a separate conversation. Call +1 (682) 254-4938 to schedule the on-site assessment.
