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.
