Polyjacking uses high-density polyurethane foam injected through small holes to fill voids beneath settled concrete. In Frisco's humid subtropical climate, hot summers dry out clay-heavy soils that expand and contract with seasonal moisture swings, causing slabs in areas like Downtown Frisco and The Star to drop unevenly. The foam expands on contact with soil moisture, creating a stable base that resists further movement better than grout in these conditions.
Access points are drilled at 18- to 24-inch intervals so the technician can control lift precisely on driveways and patios common to Stonebriar and Legacy West homes. Because Frisco's newer subdivisions sit on compacted fill that settles over time, polyjacking works well where older mudjacking methods would require larger excavations. The material cures in minutes, allowing traffic within hours even during peak summer heat when surface temperatures exceed 100 degrees.
Edge cases include slabs adjacent to Toyota Stadium parking areas or Frisco Commons Park paths where drainage patterns accelerate soil washout. Technicians watch for underground utilities common in Legacy West commercial zones and adjust injection pressure to avoid shifting adjacent hardscape. Homeowners in Plano, McKinney, and Allen often request the same approach when similar Collin County soil conditions affect pool decks and garage floors.
Technician insight
In Frisco the thing that catches most people out with polyjacking is how quickly clay soils along Legacy West and Stonebriar shift after a heavy summer rain. Homeowners often think a small dip is cosmetic until the next humid cycle opens a larger void under the slab. Checking drainage from irrigation systems before injection prevents the foam from having to fight ongoing water movement.
Settled driveway near The Star
A homeowner in a Stonebriar subdivision noticed the driveway slab dropping near the garage after two wet summers. Inspection showed a 2-inch void created by clay soil contraction under the compacted fill. Foam was injected through eight small holes, lifting the slab level with the garage threshold. The surface was ready for use the same afternoon and has remained stable through the following season.
Polyjacking Services We Offer

How it works
- 1
Site Assessment
Technician inspects slab movement, checks soil conditions around the property, and marks injection points while noting drainage patterns from nearby landscaping.
- 2
Small Hole Drilling
3/8-inch holes are drilled through the concrete at calculated intervals to reach the void without damaging surrounding surfaces.
- 3
Foam Injection
Polyurethane is injected under controlled pressure, expanding to fill voids and lift the slab to the target grade.
- 4
Cleanup and Cure
Holes are patched with color-matched material and the foam cures within minutes so the surface can be used the same day.
Pricing
Most Frisco polyjacking jobs fall in a per-square-foot range that depends on slab thickness, void depth, and access difficulty.
