Paver Base Preparation: Why Stone Dust Alone Is Insufficient

Wants to install pavers on stone dust only (no crushed stone base). 4x40 ft flat area.

Expert's Standard Method (Delayed Response Due to Family Emergency)

1. Permeable weed barrier (DeWitt brand)
2. Compacted crushed gravel/limestone sub-base
3. Stabilize with water + mechanical tamping
4. 1" builder's sand setting bed (adjust for paver size/weight)
5. Lay pavers

Why This Lasts

Sub-base prevents settling. Stone dust alone lacks structural stability. Manufacturer specs should always be consulted.
