How to Use This Calculator

Enter the total surface area in sq ft that will receive the shotcrete application.
Set the design thickness in inches as specified by engineering drawings.
Enter the rebound rate (%): 5–15% for wet-mix shotcrete, 15–30% for dry-mix.
Enter the overspray percentage for material lost beyond the target area (typically 5–15%).
Read Total Volume to Order (yd³) — this accounts for rebound and overspray waste added to net volume.
Use Application Time (hrs) to schedule crews and batch plant deliveries.
