Building safely in Pomona starts with understanding what's under the surface. The International Building Code (IBC) and ASCE 7 mandate a thorough soil mechanics study before structural design begins. This isn't just paperwork. It's about identifying the alluvial deposits and varying bedrock depths typical of the Pomona Valley. Our team integrates ASTM D2487 classification with site-specific analysis to quantify bearing capacity and settlement potential. For sites near the 71 Freeway corridor or up against the San Jose Hills, the subsurface profile can shift dramatically within a few hundred feet. We deliver data that structural engineers can use immediately to size footings or evaluate the need for ground improvement.
Pomona's location atop the alluvial fan of San Antonio Creek creates variable soil profiles that demand more than a textbook bearing capacity assumption.
