Base Depth Recommendations

  • Walkways/Patios (Pedestrian): 4" compacted base
  • Driveways (Light Vehicles): 6" compacted base
  • Heavy Duty (Trucks/RVs): 8" compacted base
  • Commercial Areas: 10-12" compacted base

Base Material Options

  • Crushed Stone (3/4"): Most common, excellent drainage
  • Crushed Gravel: Good stability, cost-effective
  • Road Base: Contains fines, better compaction
  • Class II Base: Mix of sizes, professional grade

Compaction Guidelines

  • Install in layers: 2-3" lifts for proper compaction
  • Compaction tool: Plate compactor (min 5,000 lbs force)
  • Moisture content: Slightly damp for best compaction
  • Compaction rate: Expect 20-30% reduction after compaction

Base Installation Steps

  • Excavate to proper depth (base + sand + paver thickness)
  • Install geotextile fabric to prevent base migration
  • Spread base material in 2-3" layers
  • Compact each layer thoroughly with plate compactor
  • Check level and grade for proper drainage
  • Add bedding sand layer (1") before paver installation

Important Notes

  • Poor base = failed paver installation (most common mistake)
  • Proper drainage is critical - slope away from structures
  • Use edge restraints to prevent base and paver movement
  • Consider soil conditions - clay may need extra base depth
