IMI Webinar Series - How to Design & Install Watertight Tile Assemblies
Learn how to design tile installations for wet areas based on environmental exposure classifications in the Tile Council of North America (TCNA) Handbook. We’ll cover wet area guidelines for showers, steam rooms, natatoriums, and locker rooms. Examine which substrates are appropriate for wet areas and how to properly prepare them. Next, we’ll discuss requirements for waterproof membranes including overlaps, proper thickness, treatment at returns, and terminations at drains. Learn how to achieve the required slope to drain for tile floors. We’ll also discuss critical points for various shower types including different types of drains, backer boards, and waterproofing. Finally, see what installer qualifications and tile industry credentialing programs you should consider requiring when designing and building for wet areas.
Learning Objectives:
- Understand the TCNA Handbook’s environmental exposure classifications and their unique design requirements including Commercial Wet, High Humidity, Submerged, and Heavy Moisture Exposure.
- Examine critical points of tile design and installation unique to traditional tiled shower assemblies and prefabricated shower assemblies.
- Learn the best practices and industry standards for the design and installation of different types of waterproof membranes.
- Discuss the importance of qualified labor and learn about the tile industry credentialing programs specific to installation of tile in wet areas.
