This isn't a cost. It's an investment.
The figures on this page are real and we don't hide them — that's how AE operates. But we want to be honest about how to read them. Your paver project (edge restraint scope) isn't a line-item expense; it's an investment in your home's value, your family's daily experience, and a space you'll use for the next twenty to thirty years.
When you compare bids, compare what you're investing in — the spec, the crews, the warranty, the company that will still be standing in year ten — not just the price tag. The lowest bid is almost always the most expensive build over time.
Paver Edge Restraint Arizona.
Edge restraint is the perimeter that keeps a paver field from spreading. Skip it or spec the wrong type and the outer 12–18 inches loosen within 2 seasons, joint sand washes, and the whole install starts to look like a failed patio. Here is the complete Arizona guide — restraint type by load, spike depth, install detail, and why edge restraint fails.
Restraint type by load
- Pedestrian patios, walkways, pool decks — spiked PVC or aluminum.
- Light residential driveways — heavy PVC or aluminum, 12-inch spikes into compacted base.
- Vehicular commercial, motor courts, valet — galvanized steel spiked into concrete haunch.
- Parking lots, fire lanes — steel restraint over poured concrete haunch buried below grade.
- Cast-in-place concrete curb also works as restraint on municipal / streetscape.
Install detail (all types)
- Restraint sits on the same compacted base as the pavers — never on subgrade or backfill.
- Top of restraint 1/2 inch below finish paver top.
- Spikes drive through restraint into base — 10 inches residential, 12 inches minimum vehicular.
- No landscape fabric between restraint and base — fabric prevents spike bite.
- Backfill after restraint is set — soil, decomposed granite, or turf base flush to restraint top.
- Miters at inside/outside corners; overlap at butt joints.
Concrete haunch (vehicular edges)
- Continuous poured haunch below finish grade at every vehicular edge.
- Steel restraint pinned into the haunch before pour cures.
- Haunch prevents restraint from ever pulling out under wheel load.
- Standard on hotel motor courts, parking lots, fire lanes.
Common failure modes
- Plastic restraint at a vehicular edge — spikes pull under repeated turning loads.
- Spikes into loose backfill — no bite, no hold.
- No restraint, mortar edge instead — cracks in year one.
- Fabric between restraint and base — spikes can't reach compacted base.
- Restraint sitting on subgrade instead of compacted ABC — settles with base.
Where AE writes it
- Every AE bid marks restraint type per edge on the shop drawing.
- Sample of the exact restraint product available on request.
- Base spec (2–3 inches ABC patio, 4–6 inches ABC drive, 6–8 inches ABC commercial) always paired with matched restraint spec.
- Never quarter minus under pavers — it can't compact tight enough to hold spikes.
Common questions.
Bid a paver project with proper edge restraint spec.
Send site plan or scope. AE returns a bid with edge restraint marked per zone — pedestrian, vehicular, commercial haunch — in 5–10 business days.
