Boulder's unique mix of clay soils and proximity to the mountains creates significant freeze-thaw stress on concrete. The city's older neighborhoods and university-area properties see regular settling and trip hazards, with polyjacking offering a non-disruptive repair option.
Why concrete settles in Boulder
Boulder County soils are clay-dominated with high expansion index — particularly problematic in the flatter eastern sections of the city.

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.
Yes — we use high-density polyurethane foam including bio-based formulations with 40%+ recycled content, USDA Biobased certified. The process is low-impact with no heavy equipment, no demolition debris, and no chemical runoff.
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.
