Thru Wall Structure Detail Drawing with Counter Flashing System

This Thru-Wall Structure Detail AutoCAD drawing illustrates a precise section of through-wall counter flashing termination used in exterior wall and deck construction. The drawing clearly shows metal nosing integrated with a concrete deck slab and stainless steel Sarnaclad metal components, ensuring all joints remain watertight. An adhered waterproof membrane system is detailed, including Sarnaclad metal flashing, hot air-welded seams, and acceptable sealant application at critical junctions. Fastener placement is specified at 18 inches on center for secure fixing, while pressure treated wood nailer is shown where required to support flashing termination.

The wall section further explains vertical assembly layers, including adhered membrane, nonwoven protection felt, and substrate interface. Each material layer is clearly identified to support moisture control, durability, and proper drainage performance. The AutoCAD DWG file provides clean annotations, material callouts, and construction clarity suitable for professional documentation. This drawing is ideal for architects, civil engineers, builders, and façade consultants working on waterproofing, deck edge detailing, and building envelope coordination. Available through cadbull.com subscription, this through-wall structure detail drawing supports accurate CAD drafting, construction detailing, and reliable execution of counter flashing and membrane termination systems.
