The presentation will explain what foundation waterproofing is and why it is utilized. The presenter will primarily address the challenges of pre-applied waterproofing and identify some issues that have been seen to contribute to jobsite failures.

Critical performance attributes of a pre-applied waterproofing system will be identified for consideration and to help ensure a successful, leak free waterproofing system design. Namely, the importance of long-term bond to concrete and lateral water migration resistance will be discussed and the benefits of both attributes will be explained.

The presenter will share knowledge gained from more than 50 years of waterproofing product development and the technical issues that were addressed in the development process. Finally, important pre-applied waterproofing detail and installation issues will be introduced and discussed.

The intent of the presentation is to educate about foundation waterproofing and enable the specifier to understand the critical performance attributes that will contribute to a leak free design.

Warren graduated from Old Dominion University (many years ago) with a BS in Civil Engineering Technology and has held a number of different positions in the construction industry including ready mixed concrete-technical services, Association concrete marketing & promotion, admixture manufacturer-engineering services, and building envelope-sales. Warren is responsible for working with and supporting the A&E community, installers/applicators, and distributors in the building envelope industry. Warren currently resides in Western Loudoun county with his wife, Jennifer. Together, they have four amazing daughters who have all recently started “adulting", officially making them empty nesters. With all this free time, Warren and Jennifer enjoy kayaking, golf, sporting clays, and the many wineries/breweries in Virginia.

Learning Objectives:

• Detail the ways in which below-grade waterproofing is critical to the long-term performance of a structure
• Assess project and site-specific considerations for inclusion in the design and specification of below-grade waterproofing systems
• Identify the key differences between common waterproofing systems, including pre-applied and post-applied technologies
• Better manage risk through the development of comprehensive below-grade waterproofing specifications (i.e. substrate considerations, QA/QC, detailing, etc.)
