Tips

  • Measure dimensions accurately for best results.
  • Add 5-10% extra concrete to account for waste and spillage.
  • Adjust density for specific concrete types (e.g., lightweight).
  • For irregular shapes, divide into smaller sections.
  • Consult local codes for thickness and reinforcement.
