Build a Ground-Level Deck
But because ground-level decks are so low, with framing often only inches from dirt, structural members have to endure a damp, dark environment. Use only pressure-treated beams and joists to help prevent rot and insect attack. Give the cut ends of framing members a coating of wood preservative or finish to help seal the end grain against moisture. Use only stainless steel or galvanized steel fasteners.
