Session E1
Sophisticated Stone Systems
Time & Location 8:00AM - 9:00AM | Room 318B

Wiss, Janney, Elstner Associates, Inc.

Natural stone has been used in construction of monuments and buildings since ancient times. However, being a natural material, the stone can have highly varying physical and mechanical properties; even within the same quarry. The performance of these properties will equally vary depending on the varying environmental conditions to which the stone is subjected. The performance of the stone as a building cladding, flooring or paving material will depend on the design and quality of the construction.

The seminar will focus on the selection, design and construction of natural stone cladding, flooring and paving systems. The types of available stone and finishes will be presented, as well as mineral structure, setting and anchoring materials, and the effects from environment. Discussion will also be included regarding testing, petrographic analyses and cleaning studies. Techniques used by the presenter to evaluate and repair various performance issues at exterior and interior natural stone installations will also be presented.
