Natural stone is used in a myriad of environmental exposures.  When properly selected and designed, natural stone will perform in some of the harshest exposure conditions encountered. However, the anticipated exposure may trigger the need for additional consideration, evaluation, and testing.  Environments that include elements such as freeze/thaw cycling, extreme heat, rapid thermal cycling, salt atmosphere, deicing salts, acid rain, heavy traffic (vehicular and/or pedestrian), immersion, pool or fountain chemicals, excessive dynamic building movement and/or vibration, seismic activity, extreme  wind loading (hurricane), pollutants, exhaust, or vandalism/graffiti need to be identified prior to selection and design to ensure that an appropriate stone and related systems are selected to ensure satisfactory long-term performance.  This webinar will discuss what measures need to be taken for a variety of exposure conditions..

Learning Objectives

• Learn to identify those exposure conditions that require additional consideration.
• Familiarize oneself with a variety of test methods available that help predict a stone’s performance in certain exposures.
• Discover how the stone, anchorage, and backup components act as interdependent elements of a system.
• Identify symptoms of a variety of exposures in natural stone
