Structure Wall Design Drawing with Sarnafil Membrane Drain Detail

This Structure Wall Design AutoCAD drawing presents a detailed drain section integrated within a wall and deck waterproofing system. The drawing clearly illustrates the use of Sarnafil membrane combined with Sarnafelt NWP protection layer, both adhered to ensure a continuous waterproof barrier. A Sarnaclad metal angle fastened at 12 inches on center is shown at the edge, providing secure termination of the membrane system. The detail includes a 2-inch wide Sarnaclad metal strip and a black Sarnafil marker to guide proper installation alignment. Expansion joint placement is clearly identified to accommodate structural movement and prevent cracking or membrane failure.

The section further refers to the main drain detail, showing the drain opening, membrane transition, and metal strip integration around the drainage point. All material layers, slopes, and fixing methods are clearly annotated to support accurate construction and long-term moisture control. This AutoCAD DWG file is suitable for architects, civil engineers, façade designers, and builders working on structural walls, waterproofing, and drainage coordination. Available through cadbull.com subscription, this structural wall design drawing supports professional CAD drafting, envelope detailing, and reliable execution of membrane-based wall and drain systems.
