Public Roof Inverted Roof
Traffic areas can also be implemented on inverted roofs. However they require a specially adapted design. All functional layers must be sufficiently porous for water vapour, so that the insulation does not absorb too much water. It is also necessary to determine the compressive stresses resulting from the constant load and variable load (traffic load) and make adjustments based on the compressive strength of the insulation.
Paving
- Height 60-120 mm
- Surface layer (e.g. interlocking paving, slabs, concrete)
Bedding material
- E.g. bedding stone chippings 0–5 mm (30–50 mm)
- Screed layer for surfacing material
Base Layer
Base layer of gravel 0-32 mm or 0-45 mm (0-22 on heights less than 120 mm)
