Concrete Tips:

  • Order 5-10% extra concrete to account for spillage and variations
  • Concrete typically takes 28 days to reach full strength
  • Keep concrete damp during curing for maximum strength
  • Standard concrete weighs about 150 lbs per cubic foot
  • For large projects, consider ready-mix delivery instead of bags
