Roof Slab Connection CAD with Waterproofing and Expansion Joint

This Roof Slab Connection CAD Drawing presents a detailed structural and waterproofing section showing the junction between the reinforced concrete slab and roof covering system. The drawing illustrates a slope concrete layer, cement screed finish, asphalt membrane with aluminum film, insulation treatment, and protective coating. It also highlights expansion joint placement, wall junction detailing, and impermeable paint application for moisture control. All construction layers, thickness values, and level markings are clearly indicated, making this DWG file suitable for flat roof and terrace construction projects. The file also provides precise dimensional annotations, material specifications, and installation guidelines for professional execution. Slab reinforcement details, concrete grade references, drainage slope direction, and waterproofing overlaps are included to ensure long-term durability.
