Most Jacksonville residential construction uses slab-on-grade — a concrete slab poured directly on prepared ground. Stem wall foundations are used in flood zones or on lots with significant grade changes.
Residential slabs are typically 4 inches thick with 6-inch thickening at the perimeter and under load-bearing walls. Commercial and garage slabs are often 5 or 6 inches.
