Critical Points for Tile Design and Installation - 1 LU/HSW

Tuesday, May 5, 2020 12:00 - 1:00 p.m. Eastern Daylight Time

This seminar takes a close look at the most critical elements of a successful tile project, from preliminary design through the finished installation. Applying the evaluation criteria of the Advanced Certifications for Tile Installers (ACT) to real projects and case studies, this program examines the critical requirements of ACT’s specialty areas of large format tile, membranes, mud floors and walls, shower receptors, gauged porcelain tile, and grouts. In addition to construction photos, this program uses pre-constructed physical mockups of complex tile assemblies to illustrate proper design and construction methods of critical conditions.

Learning Objectives:

  • Attendees will understand the general design and installation requirements applicable to all ceramic tile projects as set forth in ANSI A108 Installation Standards for Ceramic Tile, the Tile Council of North America (TCNA) Handbook for the Installation of Ceramic, Glass and Stone Tile, and the Advanced Certifications for Tile Installers (ACT).

  • Attendees will understand the critical points of tile design and installation unique to large format tile (LFT) and gauged porcelain tile (GPT) and GPT panels/slabs, including substrate preparation, layout, grout joint width, mortar coverage requirements, allowable lippage, lippage control systems, material handling requirements, limitations of large architectural opportunities and limitations of ultra-large unit sizes, and the effect of architectural lighting on the quality of the finish work.

  • Attendees will understand the critical points of tile design and installation unique to tiled shower assemblies and other waterproof assemblies including the types of waterproof membranes; how membrane thickness is gauged; ASTM flood testing standards; how membranes are terminated at vertical surfaces, curbs, inside and outside corners; proper pitches and slopes for wet areas; and how membranes are handled at drains and pipe penetrations for watertight installations.

  • Attendees will understand the critical points of tile design and installation unique to mortar bed (mud) walls and floors including required composition and thickness of mortar beds; appropriate specification and installation of cleavage membrane including details at laps and splices; treatment of inside and outside corners for accommodation of movement; and floating walls and floors to achieve requirements for flatness and plumb.

About the Speaker

Scott Conwell, FAIA, CDT, LEED AP BD+C

Director of Industry Development and Technical Services, IMI


At his AIA Fellowship investiture, the American Institute of Architects stated, “Through education and service, Scott Conwell has equipped thousands of architects with knowledge and tools to design high performing buildings in brick, tile, and stone; His work has significantly elevated the quality in masonry buildings nationwide.” In his 20 years with IMI, Scott has developed three areas of specialty: delivering meaningful architectural education in which design theory and constructability converge; contributing to the development of tile standards and best practices through his work on the Tile Council of North America (TCNA) Handbook committee, the BAC Tile/Marble/Terrazzo Craft Committee, and the ANSI A108 Accredited Standards Committee; and leading IMI’s team on the Masonry Detailing Series, an online collection of masonry details and technical information which set the industry standard for masonry architectural details. Scott frequently contributes articles to technical journals, he is a regular presenter at design and construction industry conferences, and he is a frequent lecturer at architectural and construction management schools. Scott is a graduate of Illinois Institute of Technology in Chicago, and a registered architect in Illinois.
