When a client’s water heater flooded their Goodwin Heart Pine engineered wood floor the insurance company called in a restoration contractor. The contractor pulled up half the floor to the point where they said the water had gone in the concrete. After three days of dehumidification they declared the concrete dry.
Following the National Wood Floor Association’s procedure we used a concrete meter that requires drilling a small hole 40% of the depth of the slab. The meter readings were much higher than recommended to install a wood floor over concrete.
We pulled up the remainder of the floor so that the entire slab could be dried. And we provided the restoration contractor with the meter readings and a study on water movement through concrete. Fortunately, they agreed to bring back the dehumidification system and get the slab to the proper moisture content.
Wood floors are not rocket science; however, they do demand a scientific approach to water and subfloors of all types. Call if you would like us to send you the research paper on how to properly test concrete for moisture content.
Best wishes for great wood floors all the time for the longterm.
