Footing depth typically runs 12 to 18 inches below grade, with columns, beams, and elevated slabs available for structural additions.
We pour monolithic slabs, stem wall foundations, footings, and garage floors for new construction and additions across Santa Barbara, matching concrete strength and reinforcement to the application — 2,500 to 4,000 PSI depending on the load.
