Wet Basement
4/18/2022 (Permalink)
Pictured is a 140 year old cement crawl space or basement of a commercial building in Three Oaks, MI. Standing water comes and goes as the water table rises and falls seasonally. The cement floor and stone walls allow moisture to seem through cracks and breaks due to hydrostatic pressure. Most basements experience this moisture intrusion at some point.
High moisture levels aren't conducive to a healthy atmosphere in a lower level. It is recommended that the relative humidity (RH) be less than 60% so bacteria doesn't grow. This basement has an average 82% RH which isn't good for the atmosphere or structural materials affected.
When dealing with high RH levels it is best not to have contents stored in the space. Mold can ruin the contents quickly. Reduce the moisture levels with dehumidification.
