Polyjacking in McKinney, TX
The bell tower over Adriatica's lake, the post-tension cable layouts under most post-2003 Stonebridge Ranch driveways, the cul-de-sacs west of US 75 where the median home was built in 2010 — that's the McKinney where polyjacking does most of its work. The 1849 Old Town courthouse footprint and the 1988 first-five-villages of Stonebridge Ranch are mudjacking territory; everything else in the 75070 ZIP trends polyjacking.

When polyjacking is the right call in McKinney
McKinney's housing stock skews modern. The 75070 ZIP's median home was built in 2010, which puts the typical lot inside the post-tension-slab construction era — a building style that sits very differently under settlement repair than the older slab-on-grade pours you find in Richardson or in Old Town McKinney. On a post-tension slab, the cable layout cast inside the concrete is what gives the slab its tension; piling slurry weight underneath risks compromising that geometry. Closed-cell polyurethane stays light. It lifts the slab without adding mass that the cables have to fight against.
The post-2003 master-planned communities are where this matters most. Stonebridge Ranch's later villages, Adriatica Village (the 45-acre Croatian-style enclave with the lake and the bell tower, built across the early 2010s), the corridor along Hardin Boulevard, and the cul-de-sacs west of US 75 — these are predominantly post-tension construction with engineered subgrade prep. The voids underneath aren't deep. The slab-and-cable assembly responds badly to slurry's hydrostatic load. Foam is the right answer, and on most calls in this part of McKinney it's the only honest one.
Polyjacking also wins when the homeowner needs the slab back fast. Foam reaches structural strength within about 15 minutes of injection; vehicle traffic is fine within 24 hours. On a 75070 driveway where the homeowner works from home, the kids are coming back from school, and the garage has to open tomorrow morning — slurry's cure window doesn't fit.

When mudjacking is a better fit (in McKinney)
We'd rather tell you on the walk-through that polyjacking isn't right for your slab than lock you into the higher-cost method when slurry would do.
If your home is in the Old Town McKinney historic core — the 1849-platted footprint around the courthouse, listed on the National Historic Landmark District since 1978 — the flatwork there is older, mixed-era, and often sits over voids deep enough that mudjacking's per-cubic-foot economics genuinely win. The same applies to the first five villages of Stonebridge Ranch, which were platted and built in 1988 and now have thirty-seven-plus years of Houston Black underneath them. At 80% of the mapped unit and 12% linear extensibility, that clay has been pulling those original-pour driveways and patios down for a long time. The voids are substantial, and slurry fills volume more economically than foam.

What polyjacking costs in McKinney
Industry-typical residential polyjacking projects run $600 to $3,000 depending on slab area, lift height, void volume, and access. Smaller corrections — a single low driveway-apron section in a Stonebridge cul-de-sac — sit near the bottom; a multi-section back-of-house project with patio plus pool deck approaches the top.
With ZIP 75070 median home values at $429,300 and median household income at $106,549, the cost-to-protect math leans hard toward lifting whenever the slab is sound. For HOA-routed common-area work in the post-2000 villages of Stonebridge Ranch and in Adriatica, polyjacking's same-day return-to-use is often the deciding factor — a closed common walk for slurry cure is a resident-complaint conversation; foam usually isn't.
The 52.4% owner-occupancy in 75070 means about half the housing stock is rental. Property managers tend to call about the trip-hazard sidewalks and the apron drops that need to be off the litigation surface fast; foam's cure window fits that calculus.
How McKinney slabs typically present (polyjacking-specific scenarios)
The polyjacking-appropriate calls in McKinney cluster around the post-2000 master-planned footprint and the modern construction methods that come with it.
Post-tension driveway aprons in post-2003 Stonebridge Ranch villages. The driveway has dropped a half-inch at the apron line; the slab is a post-tension cable assembly; slurry's added weight isn't the right answer. Foam lifts without loading the cables. This is the most common McKinney polyjacking call.
Adriatica Village courtyard walks and shared-pedestrian flatwork. The early-2010s Croatian-style enclave with its tight footprint, narrow access lanes, and resident traffic across shared courtyards favors polyjacking on both the access geometry and the cure-window dimensions. A truck-and-pump line can't always reach the interior walks, and the residents won't tolerate an overnight closure.
Pool decks settling away from the pool shell on newer Stonebridge homes. Added weight near a pool's bond beam isn't the right answer geometrically — foam's lightweight fill lifts the deck without loading the pool's structural perimeter. A meaningful share of post-2005 Stonebridge homes have pool decks, and the polyjacking framing fits the new-build profile.
A/C condenser and pool-equipment pads tilting toward the foundation. Small pads with shallow voids and light loads are foam scenarios across the McKinney footprint regardless of village age — the truck setup for slurry doesn't pay back on this size of slab.
Your McKinney polyjacking FAQ
Is polyjacking OK for a post-tension slab? Yes — and on most post-2003 McKinney slabs, it's the better choice precisely because it doesn't add weight that the post-tension cables have to fight against. A controlled foam injection puts very little stress on the slab itself. The risk is uncontrolled injection — too much volume at one port — and that's an experience problem, not a method problem.
How fast can I drive on the slab after polyjacking? Typically 24 hours after the last injection on a McKinney driveway, sometimes sooner in warm weather. Foot traffic is fine within an hour or two. Cold weather extends the window because the chemistry runs slower in low ambient temperatures.
Will the foam degrade or shrink over time? No. Cured polyurethane is dimensionally stable, hydrophobic, and chemically inert at residential soil exposure. It doesn't biodegrade in the ground and doesn't compress meaningfully under residential loads.
Does polyjacking work for HOA-managed common areas in Stonebridge Ranch? Yes — and this is usually the deciding factor on shared courtyards and sidewalks. Foam's structural cure within about 15 minutes lets residents back on the surface the same day. We provide the documentation HOAs need for the maintenance-ledger entry.
Will the foam crack my driveway as it expands? A controlled injection paces the volume in short pulses, watching the lift response between bursts. Uncontrolled injection can stress a slab; controlled injection doesn't. We pre-stitch surface cracks where they exist before the lift.
Does drought matter for the lift? Yes. The 14 weeks where at least a quarter of Collin County sat at D1+ over the last year have been working against the clay's water content steadily. The lift addresses the slab; the soil keeps doing what it does. Call +1 (682) 254-4938 to schedule the on-site assessment.
