Calcolatore di Muro di Contenimento

How to use it

1. Courses high: ceil(0.9 m ÷ 0.2 m) = 5 courses
2. Blocks per course: ceil(6 m ÷ 0.4 m) = 15 blocks
3. Total blocks: 15 × 5 = 75 blocks
4. Base gravel depth: 20 cm; Volume: 6 × 0.6 × 0.2 = 0.72 m³ ≈ 1.1 tonnes

Common mistakes

• ⚠️ Not burying the first course below grade — minimum 10% of wall height
• ⚠️ Forgetting drainage pipe and gravel backfill behind the wall
• ⚠️ Using standard blocks instead of approved retaining wall blocks for walls > 90 cm
