The base is where the time goes
Settling comes from three things: excavation that was too shallow, base that was not compacted in lifts, or missing edge restraint. All three are invisible once the pavers are down, which is why they are the easiest corners to cut.
- Excavate deep enough for the load: deeper for driveways
- Compact base material in thin lifts, not one thick layer
- Install edge restraint so the field cannot spread
Clay soil needs more
In parts of Sun Valley and the North Valleys, heavy clay holds water and heaves. Those sites need deeper excavation and careful compaction to keep the surface on its line.
