Castle Rock is one of the fastest-growing cities in Colorado, with thousands of new builds on engineered fill soil. Fill compacts over time, creating voids under slabs that cause settlement within the first few years of occupancy — earlier than most homeowners expect.
Why concrete settles in Castle Rock
Douglas County combines clay and engineered fill in newer developments. Fill soil compaction under new concrete is a leading cause of early-stage 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.
New developments are frequently built on engineered fill soil that wasn't fully compacted before concrete was poured. That fill continues compacting under load, creating voids and causing the slab to sink. Polyjacking fills those voids and stops the movement.
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.
