Building a Paver Patio on a Former Above-Ground Pool Site

A homeowner removed an above-ground pool, leaving a 6-inch depression. They plan 4 inches of bank gravel base + 2 inches of mason sand/stone dust for pavers, and ask whether to remove the existing 5-inch sand bed or build over it.

Expert Opinion: Build Over It

The pool's weight likely compacted the sand bed adequately over time. Since you'll compact the new 4-inch gravel base with a plate compactor (standard paver installation practice), the existing sand provides a stable sub-base.

Critical Success Factors

• Edge Restraint System: Essential—use pavers on edge or metal/plastic restraints to prevent lateral spreading
• Proper Compaction: Plate compact the gravel base in lifts
• Reference: Grounds Maintenance installation guide

This approach saves significant excavation labor while providing a stable foundation for your new patio.
