Structure Expansion Joint Detail with Stainless Steel Anchor System

This structure details an AutoCAD drawing that illustrates a clear expansion joint section designed for concrete structural systems. The drawing shows an existing expansion joint treated with adhered Sarnafil membrane and Sarnafelt NWP waterproofing layers to ensure flexibility and moisture protection. A stainless steel or galvanized metal plate is positioned over the joint to allow controlled movement while maintaining surface continuity. The stainless steel spike anchor is detailed, penetrating the slab to secure the plate assembly firmly without restricting joint performance. The section clearly represents material layering, joint alignment, and the interface between old concrete and waterproofing components.

The structure details DWG file is drafted with clean line work, accurate proportions, and construction-oriented annotations suitable for professional documentation. It highlights how expansion joints are protected while accommodating thermal and structural movement. This structure details download file is useful for architects, civil engineers, interior designers, and builders working on slabs, roofs, podiums, or terrace structures. The drawing is compatible with AutoCAD and can be coordinated with Revit, 3d Max, and Google SketchUp workflows, making it a reliable reference for expansion joint detailing in concrete structure design.
