How long does a paver job actually last in Arizona?

An AE-spec paver assembly is built to last 25+ years with normal residential use. The lifespan is decided underground — base depth, sand bed, and joint sand — not by the stone you can see.

AE canonical paver assembly

Patios and walkways: 2–3 inches of compacted ABC base.
Driveways: 4–6 inches of compacted ABC base, deeper for higher-load or build-up conditions.
1 inch of bedding sand, screeded — every job, no exceptions.
Polymeric joint sand swept, set, and activated per manufacturer spec.
Quarter-minus is never used under pavers (turf base only).

Why most early failures happen

Too little ABC base for the load.
Skipping the bedding sand layer or using a substitute.
Regular silica sand in joints — washes out, weeds in.
Edge restraint omitted or under-spec.
Drainage routed across the field instead of around it.

Arizona context

Monsoon flow and 110°+ expansion cycles punish weak base and joint detail.
Caliche layers and expansive soils are accommodated through base depth and sub-base prep, not ignored.

When the answer changes

Vehicle loads above standard residential require a heavier base.
Slopes above ~5% need engineered drainage and may shift the assembly.

Real AE example

We routinely service AE paver driveways installed 15–20 years ago that still sit flat — same ABC depth, sand bed, and polymeric joint sand we use today.
