Clay Soil Drainage Steps for Shed Foundations

Greater Houston clay expands and contracts with moisture. Sheds on unprepared clay shift and crack slabs within two seasons.

Do this sequence:

1. Excavate 8–12 inches below grade.
2. Install 4–6 inches of crushed limestone base.
3. Add geotextile fabric to separate soil layers.
4. Slope the base 1/4 inch per foot away from the structure.
5. Compact in 2-inch lifts before framing.
6. Install perimeter drain pipe tied to existing swales.

Additional clay-soil aware actions include testing soil moisture before pour and adding French drains if the lot sits below street grade.
