Intensive Roof Planter Systems and Structural Loads

This technical illustration provides a cross-sectional and comparative analysis of rooftop planting systems. It details the subterranean layers required for healthy plant growth and proper drainage, while simultaneously illustrating the direct correlation between planter depth, plant size, and the resulting structural load on a building's roof level.

Key Components & Features

Multilayered Substrate System: The cross-section reveals a sophisticated layering strategy designed for longevity:

Filter Fabric: Separates soil from the drainage layer to prevent silt from clogging the system.

Gravel Layer: Acts as a primary drainage medium to allow water to move freely toward the outlet.

Anti-Root Membrane: Protects the structural concrete from root pe*******on and water damage.

Drainage Infrastructure: Includes a Slope Screed to direct water toward a Grate and a 100mm Drain Pipe, ensuring the roof remains watertight and free of standing water.

Scale of Vegetation: The diagram categorizes greenery by height—ranging from Grass to 3m Trees—to demonstrate how different species require varying soil volumes.

Weight Load Analysis: Provides specific structural data (measured in kg/m
2) showing that as the planter depth increases from 150mm to 1500mm, the load increases significantly from 240 kg/m
2 to 865 kg/m 2 .

System Overview

The image serves as a critical guide for architects and structural engineers when integrating "green roofs" into urban design. It emphasizes that aesthetic greenery requires a heavy technical "under-life" of membranes and drainage. The primary takeaway is the significant weight increase associated with larger vegetation; planting a 3-meter tree requires a structural capacity nearly four times greater than that of a standard lawn.
