This document provides a standard operating procedure for expansion joints between concrete structures like columns, beams, and slabs. It outlines the materials, responsibilities, and step-by-step procedure for installing extruded aluminum plates and Shailtex boards for expansion joints that are 50mm or 100mm thick. The procedure involves surface preparation, cutting the Shailtex boards to size, placing them in the groove flush with the surface, securing them, cleaning the surface, and applying sealants. Records to be documented include request for inspections, level sheets, technical data sheets, and material test certificates.
