Speaker and Topic Information:

Picture1.pngCharles J. “Chuck” Muehlbauer is the Technical Director of the MIA + BSI (Marble Institute of America and Building Stone Institute), a stone industry association comprised of more than 2,000 member companies from over 50 countries. Muehlbauer is now in the 4th decade of his career in the stone industry, with experience in quarrying, fabrication, installation, anchorage design, stone selection, industrial stone applications, laboratory testing, stone forensics, estimating, and both domestic and international sales.  Muehlbauer is a voting member of seven national technical committees, including ASTM Committee C-18 on Dimension Stone, where he currently serves as Chairman.

Course Title: STONE:  Origin, Composition, and Properties

Presenter:  Chuck Muehlbauer, Technical Director, MIA + BSI

Learning Objectives:

  • Learn about the Origin and Composition of natural stone
  • Discover how these two factors determine the characteristics of a stone variety
  • Understand the difference between Industry classifications vs. Geological classifications
  • Discuss Stone Properties and Measurement of those Properties

Course Description:

This session will focus on the basics of stone formation and composition, unlocking the basic geological basis that makes each variety of stone a unique product.  The influence that formation and composition have on performance will be discussed, as well as performance predictions that can be made just based on knowing the makeup of the stone fabric.  Standard tests used to measure physical and mechanical properties of stones will be explained. 


Course Title: Stone Wall Cladding

Presenter: Chuck Muehlbauer, Technical Director, MIA + BSI

Learning Objectives:

  • Understand the advantages and limitations of adhered stone attachment systems, and learn how to choose between adhered or anchored systems for a particular project.
  • Develop awareness of applicable industry standards governing light stone (≤ 30 mm) cladding systems.
  • Become familiar with common, conventional anchoring hardware.
  • Learn how recently developed energy codes (ASHRAE) influence stone anchorage design. 

Course Description:                                

This session will focus on the light commercial construction projects, both interior and exterior.  Installation of stone over metal stud frame and CMU backups, with both adhered and anchored systems will be discussed in this session.  Anchor positions versus stone panel behavior will be explained, with descriptions of a variety of common anchoring devices suitable for thin veneer (≤ 30 mm).  Revisions to traditional stone anchorage methods as a result of recent energy codes will also be explored.



Bill Halquist is the President and co-owner of the Halquist Stone Company, which has been continually been family owned since the founding in 1929.  Bill has been on the board of directors of the Building Stone Institute, Marble Institute of America, Allied Stone Industries, and the Wisconsin Masonry Alliance.  Bill is presently Chairman of the Natural Stone Council, an umbrella group of all major stone associations, which champions Sustainability in the Industry.
