Use this formula to calculate how many bags you need:
Bags required = Length (m) × Width (m) × Depth (m) × 110

Example: A pothole 0.6m × 0.6m × 0.03m deep = 0.6 × 0.6 × 0.03 × 110 = 1.2 bags (round up to 2)

Approximate coverage per 20kg bag:
• 30mm depth (standard repair): 0.33m²
• 50mm depth (deeper repair): 0.20m²
• 75mm depth (full reinstatement): 0.13m²
