Pavers Over Concrete vs. Aggregate Base: Which Is Better?

For a 1,000 sq. ft. patio in New Jersey, both methods work—but cost and site conditions dictate the choice.

Sand/Aggregate Base (Standard)

• 6" compacted crushed stone + geotextile fabric + 1" bedding sand.
• Cheaper, permeable, flexible with freeze-thaw cycles.
• Requires stable, well-draining subsoil.

Concrete Base (Optional)

• Necessary if grade changes require steps or walls.
• Better for wet, expansive, or poorly drained soils.
• More expensive; pavers set in mortar or sand atop slab.

Two-Level Design Note

If you want a raised landing at the door, a concrete base with block retaining walls simplifies the transition. Otherwise, a well-built aggregate base handles pedestrian loads perfectly.
