Lone Tree is a newer Douglas County city built largely in the 1990s and 2000s on engineered fill — the kind of soil that compacts for years after construction ends. Driveways and patio slabs that looked perfect at closing can show significant settlement within the first decade.
Why concrete settles in Lone Tree
Douglas County engineered fill in Lone Tree developments compacts unpredictably under concrete slabs — one of the primary reasons newer homes see early settling.

How it works
Dime-sized holes drilled through the slab. No equipment, no demolition.
High-density polyurethane expands to fill every void and compact the soil beneath.
Concrete rises to grade, foam cures in minutes, ports patched flush. Done.
Lone Tree's newer subdivisions are built on engineered fill that wasn't fully compacted before concrete was poured. That fill continues compacting under load for years, creating voids and causing slabs to drop — sometimes within the first few years of ownership. Polyjacking fills those voids and stabilizes the base.
Most residential jobs run 30–50% less than full concrete replacement. We provide firm, written quotes after a free on-site assessment — no surprises.
The foam reaches load-bearing strength in about 15 minutes. You can typically drive on the repaired concrete the same day.
