Robert Higgins, a renowned concrete expert consultant, explains the best processes for detecting moisture in the concrete. All tests can be good when performed correctly, but the accurate interpretation is key for them to be meaningful. Some tests can be more misleading than helpful if not fully understood. Not all tests will give the data necessary to help avoid moisture-related problems occurring at the time of installation. And this is exactly when the majority of moisture-related problems occur.
The Tramex Dec Scanner is the Original Non-Destructive Moisture Scanner for Flat and Built-up Roofing systems. This video provides assembly instructions and guidelines on how to set up & use the Dec Scanner when performing Flat & Built-up Roofing surveys as per ASTM D7954 standard.
John Hull, the President of Gulf Infrared, LLC, talks about the Tramex Dec Scanner and the necessity of commercial roof moisture surveys. Currently, only approximately 32% of commercial roofs were torn off and replaced actually needed to be. So, two-thirds of the commercial roofs that were torn and thrown in landfills could have been candidates for repair, if proper moisture testing was implemented. This has huge environmental implications from unnecessary roof replacements, and some states have begun to look at and implement mandatory roof moisture testing.
The Tramex Dec Scanner is the Original Non-Destructive Moisture Scanner for Flat and Built-up Roofing systems. Portable and easily transportable in a rugged flight case, the Dec Scanner provides instant and continuous readings with adjustable sensitivity for a variety of flat roof makeups, allowing you to locate and map moisture issues as you go.
Andrew Rynhart, the Tramex CEO, discusses how the ASTM F2170 test only measures the vapor in concrete (RH) and explains the importance of also measuring concrete moisture content (%MC) with quantitative non-destructive tests and identifying dew point issues.
