The North Texas Chapter of IIBEC is excited to announce that on Thursday, May 28th, we will be providing a free online live presentation on pre-applied blindside waterproofing systems. This presentation will also include some hands-on training that you can complete from the safety and comfort of your home! Each registrant will receive a mock-up kit that will be mailed to your home (or other address you provide) to be assembled by you during this event. You must register before May 20th to receive a kit in time. A link to attend the online presentation will be sent out prior to the event. Additional information regarding the presentation and hands-on training is included below:

Presentation: The Physics Behind Lessons Learned in a Full-Size Blindside Mock-Up

Burying a pre-applied waterproofing system between an earth retention system and newly installed concrete, never to be seen again, creates a difficult scenario whereby designers, manufacturers, and contractors are left to wonder just how well their system will perform. SmithGroup (an architectural engineering firm) partnered with a design-build contractor to develop a new university laboratory building. The building included two stories of below-grade construction and was placed at the corner of the project site close to the intersection of two streets. Based on previous success, the design-build contractor proposed the use of a specific blindside system. For the proposed system to be approved for the project, both parties agreed to perform an evaluation. A significant part of the evaluation process included the assembly and forensic deconstruction of a full-size structural shotcrete mock-up.

There are three areas of concern typically posed to all pre-applied waterproofing membranes:

• Does the system bond to the concrete?
• Will the system survive the installation of the structural shotcrete?
• Can the system resist lateral water migration?

From the lessons learned during the assembly and deconstruction of the mock-up, we will review the findings and use scientific methods with applied physics to evaluate the original assumptions and validate the findings.

Hands-on Training: Pre-Applied Waterproofing Mock-up Kit

Experience the feeling of working with the materials used and evaluated in the “Full-Size Blindside Mock-Up” while never leaving he comfort of your office or home. Each individual or group participating in the training will receive a pre-applied waterproofing mock-up kit where the shipping box become the training mock-up and contains various waterproofing details for you to install like selvage edges, flashing, outside corner, end-lap, etc.. Join along as our speakers guide us through this mock-up.

Speakers: David Leslie, Jerry Carter, and Joe Millican

David Leslie’s experience includes product development, contracting, and consulting. His 30 years of experience have provided him with a unique insight into numerous aspects of the building enclosure. He is a published author, public speaker, expert witness, and holder of multiple patent applications. Leslie is an active member of IIBEC, a Registered Waterproofing Consultant, an ABAA Licensed Field Auditor, and a member of SWRI. It is his core belief that there is no good reason for a building to leak, and he has committed much of his career to keeping people dry.

As a member of SmithGroup’s Building Technology Studio, Jerry Carter’s primary work experience focuses on the analysis and development of exterior building enclosure systems. He specializes in the design and restoration of plazas and garden roofs, conventional roofing, and below-grade waterproofing. He also plays a key role in developing and maintaining SmithGroup’s master specifications related to the exterior enclosure. Carter received his B.S. in architecture and his Master of Architecture from Lawrence Technological University. He has been with SmithGroup for over 11 years. He is a current vice chair for the local chapter of the Building Enclosure Council.

Joe has over 3 decades in the construction industry and is the inventor of the Polyguard Underseal Pre-Applied waterproofing system. His field experience is relied upon by designers, general contractors, and installers around the world. He is a member of both IIBEC and SWRI, as well as, a developer of the SWRI Certified Installer training program.
