Choosing base depth
Patios that only see foot traffic usually get 4 inches. Clay soil, poor drainage and cold winters call for 6 inches. Driveways need much more. See how deep paver base should be.
Bags or bulk
At 4 inches this is about 320 small bags, which is a lot of lifting. Bulk paver base or crushed stone with fines (often sold as crusher run, road base or 3/4 minus) costs far less per ton.

Compaction
Spread the base in 2 to 3 inch lifts, dampen it and run a plate compactor over each lift. Slope the base about 1/8 to 1/4 inch per foot away from the house. Then screed 1 inch of bedding sand on top.
Ordering materials
Buy pavers from one production run where possible so the color matches. Ask how many square feet a pallet covers and whether partial pallets are sold. Bulk base and sand delivered together usually beat bagged products on cost.
Common mistakes
Skimping on base depth, skipping compaction and using too much bedding sand are the most common errors. Thick sand shifts and causes dips. Another is forgetting edge restraint, which lets pavers creep outward over time.
Slope and drainage
Patios should slope away from the house about 1/8 to 1/4 inch per foot so water does not pool against the foundation. Build the slope into the compacted base so the sand bed and pavers stay a consistent thickness.
