Slab thickness and base preparation
The most common mistake in slab projects is under-specifying thickness and skipping base preparation. A 4-inch slab on a poorly compacted base will crack and settle under load. Typical residential slab thicknesses: 3.5-4 inches for utility pads; 4-5 inches for general flatwork; 5-6 inches for RV parking or heavy equipment.
