Crushed glass cullet was used below a sidewalk as fill and leveling agent in place of sand and gravel at 304 West Bay Drive in Olympia, WA. The material is made up of glass otherwise unsuitable for typical glass recycling and is created at a local quarry. Due to knowledgeable building officials and engineering examiners in Olympia, the material proved to meet the IBC compaction requirements with no additional procedures to permit the project. The project was successfully completed and crushed glass cullet proved to be safe and cost effective.
