Our Forensic Wateproofing Expert Delivers a Successful Lunch and Learn Program for SOM Los Angeles

Terra-Petra’s Forensic Waterproofing Expert, Barry Taheri, presented his sixth lunch and learn program for global architecture, planning and design firm, Skidmore, Owings and Merrill (SOM), at their downtown Los Angeles offices on Grand Avenue, on August 29, 2018.

In his presentation, “The Principles of Building Enclosure Systems,” Taheri provided info on the importance of building waterproofing and the benefits of investing in mock-ups, along with a few live demonstrations. Our delicious lunch was catered by Mendocino Farms.

Terra-Petra’s presenter Barry Taheri was more than happy to stay after the presentation to field questions from many of the audience members. We want to thank SOM for their time as we were very impressed with this world-class firm and hope to be able to work with them on projects in the near future.

Terra-Petra Waterproofing Division provides inspection services for new Trammell Crow Residential project in West Hollywood

Domain, a mixed-use development from Trammell Crow Residential, is now complete in West Hollywood. Terra-Petra Waterproofing was called in to provide building waterproofing inspection services prior to final close of project.

Located at 7141 Santa Monica Boulevard, just east of La Brea Avenue, the property features a seven-story building containing 166 apartments atop 9,000 square feet of ground-floor commercial space.  The newly opened mix of studio, one- and two-bedroom apartments.

Architecture firm Studio One Eleven designed Domain, which features a three-story opening along Santa Monica Boulevard.  Building heights gradually step down as the property approaches the lower-scale residential neighborhood to the north, creating space for outdoor decks.  Other amenities are located within a central courtyard, including a swimming pool.

The Use of Electronic Leak Detection (ELD) on Waterproofing Membranes over Concrete Surfaces

Waterproofing membranes are a key element in building enclosure systems—a key element that ultimately gets covered up by a variety of finish materials including landscaping, green roofs, topping slabs, pavers and so on. As most of us know, excavation to expose a failed waterproofing membrane for repairs can be prohibitively expensive and in some cases impossible. For this reason, many designers are choosing to specify integrity testing to verify that the waterproofing membrane is free of discontinuities and penetrations through the membrane prior to the installation being permanently covered. When integrity testing is not specified, many contractors are often performing this type of testing voluntarily to avoid future problems or “call-backs.”

The most common integrity testing method is the flood test. Flood testing is typically performed by flooding waterproofed horizontal surfaces with at least two inches (50 mm) of water for a period of up to 48 hours. Temporary dams are often constructed to partition the test areas, provide an up-turned plaza edge and control the depth of the flood testing. During the flood test, access to the underside of the flooded areas is necessary for a visual inspection of water leakage. However, in the case of a membrane failure (leak), flood testing indicates only where water is penetrating through the entire assembly within the test area, not the location above where water is breaching the membrane. In addition, flood testing cannot be performed on vertical surfaces or at locations where the underside of the slab is not accessible.

The aforementioned restrictions and lack of conclusive data associated with flood testing has enabled Electronic Leak Detection (ELD) to gain momentum as a viable alternative to traditional flood testing. This article will focus on the different types of ELD and the applications where ELD is or is not well-suited.

Detec Systems visited Terra-Petra’s Los Angeles office this week to conduct a comprehensive education and training session to promote their innovative product line of leak detection technologies. Detec provides leading-edge technology in the field of electronic leak detection (ELD), by way of membrane integrity testing and scanning, and automated structure monitoring. The training session included a classroom like session followed by field training on a jobsite.

The Terra-Petra Waterproofing Division is certified to conduct ELD testing throughout Southern California for numerous types of fluid-applied waterproofing and roofing systems in compliance with ASTM 7877-14. This includes any thermoplastic roofing system, any asphalt based waterproofing, traffic coatings, hot and cold fluid applied membranes and some bentonite systems (as long as they have thermoplastic reinforcement).

Terra-Petra employs the use of the Detec Systems Roof Membrane Integrity Scanner (RMIS) to accurately identify breaches in new and existing membrane systems. Many contractors are using a 24-48 hour flood test to check for breaches in these types of waterproofing assemblies. While this method can identify water leaks, it is time consuming and less cost effective. The benefits of the RMIS technology is that breaches and other imperfections can be identified, repaired and re-tested the same day, saving valuable time, resources and money for any project.
