Flat Roof Passable System CAD Detail Showing Roof Layers and Section

This AutoCAD CAD file presents detailed construction information for a flat roof passable system, including roof layout, sectional elevation, and material layer details. The drawing illustrates a flat roof structure designed with a slope below 1.5 degrees or a fall ratio of 1 in 40 to ensure proper drainage. The CAD detail shows the arrangement of structural slab, insulation layers, waterproof membrane, protection layer, and surface finish used for accessible roof systems. Precise measurements of slab thickness, insulation depth, waterproofing placement, and roof finish layers are clearly indicated to assist architects, civil engineers, and builders in accurate roof design and construction planning.
