Case Study: Commercial Foundation Stabilization at Corona Millworks—Phoenix, AZ

Soil testing using a dynamic cone penetrometer (DCP) revealed unstable subgrade conditions—specifically, pockets of low-density soil between 6 and 10 feet deep. These zones had likely formed from past compaction inconsistencies during site prep or erosion over time.

In commercial properties, foundation settlement doesn’t just threaten the structure—it can disrupt operations in serious ways. Slab movement can throw off heavy machinery alignment, cause safety hazards at loading docks, or create uneven wear on forklifts and inventory systems.

These risks make early detection critical. Geotechnical testing, like DCP, allows us to map soil strength layer-by-layer and target the exact depths that need stabilization—avoiding guesswork and unnecessary costs.
