Structural engineering - green roofs 1

[haj1]

Can any one please tell me what loads should take in KN/m2 for a saturated extensive type of green roof having a depth between 75-100mm.

I would say 2 kPa per 100 mm for the saturated soil load. But the "green roof" installer should be able to give you a better number.

Look for information from a few different manufacturers. They usually provide this.

2.4 KPa is about 50psf. This is a growing green roof load of short bush/tall grass height.
