Crawl Space Encapsulation in Tucson, AZ

Crawl Space Encapsulation in Tucson: local conditions

Tucson, AZ sits on expansive clay and caliche in a mostly arid landscape and has an arid climate with about 8–13" of rain a year. The local water table is generally low, though monsoon storms cause flash flooding, with minimal winter freeze–thaw cycling, and slab-on-grade dominates and basements are uncommon. In practical terms, expansive clay and sudden monsoon flooding drive slab movement and drainage problems — which is exactly why crawl space encapsulation is a common need here.
