Abstract/Summary
The city of Sacramento and its concrete foundations face one of the most challenging conditions in the flooring industry, high RH Moisture. RH Moisture or Relative Humidity Moisture is one of the main causes for flooring systems to fail. The source of High RH Moisture consists of surrounding geographic features like rivers, flood plains, and elevation, as well as improper or nonexistent use of a vapor barrier beneath the concrete foundation. Mapping and other data is used to support these claims. If a flooring system is not properly prepared for high RH Moisture levels, issues such as bubbling, delamination, and glue becoming unadhered can all lead to mass amounts of damage. The data used consists of hundreds of RH Moisture tests by Wagner Meters and will be used to prove the issue of high RH Moisture persists in the Sacramento area. The RH Moisture testing method has become an industry favorite compared to other methods due to the capability to read the middle of the concrete slab, where others only give surface readings. Once an RH reading is established it is up to the contractor to find the best solution to the Moisture problem using a topical moisture barrier
