TL;DR
Paver base is the structural foundation beneath an interlocking pavement: geotextile over compacted subgrade, then 4 to 12 inches of crushed aggregate compacted in lifts, topped by a 1-inch screeded bedding layer of concrete sand. Depth scales with use and climate — patios need less, driveways and freeze-thaw regions more — and compaction in thin lifts is what prevents future settlement.
What it means
Paver base is the structural foundation beneath an interlocking pavement: geotextile over compacted subgrade, then 4 to 12 inches of crushed aggregate compacted in lifts, topped by a 1-inch screeded bedding layer of concrete sand. Depth scales with use and climate — patios need less, driveways and freeze-thaw regions more — and compaction in thin lifts is what prevents future settlement. Since the base is invisible at handoff, its specified depth and material in the contract is the owner's only quality lever.
