Build a Patio: Materials Checklist
A poured or paver patio is mostly three layers: compacted gravel base, bedding or concrete, and the surface. Work out each quantity before you order.
Excavate and compact the base
Use 4 inches of compacted gravel for patios, 6 for driveways.
Pour a concrete slab (if not using pavers)
4 inches thick is standard for patios; add wire mesh or rebar.
