🚚 Ordering Tips

  • Minimum truck delivery is usually 1 cubic yard
  • Short load fees apply under 5 yards
  • Saturday delivery costs extra

🛠️ Essential Tools

  • Wheelbarrow for moving concrete
  • Shovels and rakes for spreading
  • Screed board for leveling
  • Float for smoothing surface
  • Edger for clean edges
  • Broom for texture (non-slip)

⏱️ Working Time

  • Initial set: 30-45 minutes
  • Final finish: 2-4 hours
  • Walk on: 24-48 hours
  • Drive on: 7 days minimum
  • Full strength: 28 days

🌡️ Weather Considerations

  • Ideal temp: 50-75°F
  • Too hot: Concrete sets too fast
  • Too cold: Use cold weather mix
  • Never pour on frozen ground
  • Cover if rain expected
  • Keep moist for 7 days to cure

Pro Tip: For projects over 3 cubic yards, truck delivery is almost always more cost-effective than bags. For 3 yards, you'd need about 150 sixty-pound bags!
