Roof has waterproofing over mulch how much

Roof planting still has a lot of things to pay attention to, I choose the most important to introduce to you.

Roofing mulch planting, soil thickness is directly related to the effect of planting as well as success or failure.

From the planting point of view, it is definitely the thicker the soil layer the more favorable, but the roof planting because of the limitations of the hardware facilities, taking into account the roof of the load-bearing problem, but also taking into account the problem of soil transportation, so it is certainly not possible to have the ground planting so good conditions. However, the house mentioned in the question is said to be a frame shear structure, this structure is still very strong, general high-rise are using frame shear structure, so the load bearing is certainly not a problem. If you have the conditions, mulch can be slightly thicker, 50 to 60 centimeters thick can be, if the conditions are not enough to have a thickness of 30 centimeters is also completely sufficient, the thickness of the future planting of water and fertilizer basically will not have any problem
