Concrete Foundations in Jacksonville, FL
Slab-on-grade, monolithic slab, and stem wall foundations to Florida Building Code. FL Certified Building Contractor CBC1269043 since 2013.
Foundation type selection for NE Florida soil conditions
Jacksonville's sandy, high-water-table soil creates specific foundation design requirements. The most common residential foundation type in Duval County is the slab-on-grade, either monolithic (thickened edge) or with a grade beam. The sandy soil drains well but also settles unevenly under load, especially in low-lying areas near the St. Johns River and the Beaches.
We hold Florida Certified Building Contractor license CBC1269043, which qualifies us to pull foundation permits and act as prime contractor on residential foundations. Structural foundation work requires a CBC-licensed contractor. Specialty concrete contractors without CBC licensing cannot legally pull permits for this work.
Every foundation we pour begins with a soil assessment to verify sub-base bearing capacity. Clay-heavy soils common in Clay County require additional compaction and vapor barrier treatment. Sandy fill soil requires verification of proper compaction before forming. We document this for the building permit inspection.
