Passable Roof Section Detail With Drain Pipe And Structural Layers

Passable roof section detail drawing showing the structural composition of a walkable roof system designed for durability and proper drainage. The section illustrates the roof surface layer supported by structural pedestals above protective layers and insulation. Below the top surface, the drawing represents waterproof membrane placement, thermal insulation, protective screed layer, and structural slab arrangement that supports the load of pedestrian movement. The drainage outlet pipe positioned at the center of the roof section allows rainwater to flow downward through the vertical pipe system connected to the building drainage network.
