Follow relevant standards and green roofing field practices for green roof load assessment. Consult local codes where applicable.
Material Quantity FormulaFormula
Volume = length × width × depth — confirm units before ordering.
Green Roof Load Assessment BenchmarksTable
Key parameters and target values for quality assurance.
| Parameter | Target | Notes |
|---|---|---|
| Moisture | Within spec | Test before cover |
| Compaction | Uniform layers | ≤150 mm lifts |
| Safety | PPE worn | Stop if unsure |
Load First
Calculate saturated soil and plant load before ordering media — overweight roofs fail structurally.
Membrane Integrity
Protect waterproof membrane from punctures during every layer install.
Fall Protection
Use harness and guardrails whenever working within 6 feet of roof edge.
Safety Notes
- Never install intensive green roof without engineer sign-off.
- Include irrigation water weight in calc.
