Pool Concrete Calculator

The calculator follows this process, based on standard construction practices:

Floor Volume:
- Area = length × width.
- Volume = area × floor thickness (converted to feet).
- Example: 20 ft × 10 ft × 0.5 ft = 100 cubic feet.
Wall Volume:
- Average depth = (shallow depth + deep depth) / 2.
- Side walls area = 2 × length × average depth.
- End walls area = width × shallow depth + width × deep depth.
- Total wall area = side walls + end walls.
- Volume = total wall area × wall thickness (converted to feet).
- Example: Avg depth = (3 + 6)/2 = 4.5 ft, side walls = 2 × 20 × 4.5 = 180 sq ft, end walls = 10 × 3 + 10 × 6 = 90 sq ft, total = 270 sq ft, volume = 270 × 0.5 = 135 cubic feet.
Steps Volume:
- For each step:
  - Tread volume = tread depth × step width × floor thickness.
  - Riser volume = step width × riser height × wall thickness.
  - Total step volume = tread + riser.
- Sum all steps’ volumes.
- Example: Tread = 1 ft × 10 ft × 0.5 ft = 5 cubic feet, riser = 10 ft × 0.5 ft × 0.5 ft = 2.5 cubic feet, total = 7.5 cubic feet per step.
Total Volume:
- Sum floor, wall, and steps volumes in cubic feet.
- Convert to cubic yards (divide by 27).
- Add overspray (e.g., 12.5% = × 1.125).
- Example: Total = 100 + 135 + 7.5 = 242.5 cubic feet = 8.98 cubic yards, with 12.5% = 10.10 cubic yards.

Example Calculation

Inputs:
- Length: 20 ft, Width: 10 ft, Shallow Depth: 3 ft, Deep Depth: 6 ft.
- Floor Thickness: 6 inches, Wall Thickness: 6 inches.
- Steps: 1 step with Tread Depth: 1 ft, Riser Height: 0.5 ft, Step Width: 10 ft.
- Overspray: 12.5%.
Output:
- Floor: 100 cubic feet (3.70 cubic yards).
- Walls: 135 cubic feet (5.00 cubic yards).
- Steps: 7.5 cubic feet (0.28 cubic yards).
- Total: 8.98 cubic yards.
- With Overspray: 10.10 cubic yards.
