Crawl Space Encapsulation in Houston, TX

Crawl Space Encapsulation in Houston: local conditions

Houston, TX sits on highly expansive clay and has a varied climate, humid in the east and arid in the west, with heavy storms. The local water table is variable — expansive clay swells and shrinks sharply, with mild winter freeze–thaw cycling, and slab-on-grade dominates and basements are rare. In practical terms, expansive clay is one of the nation's leading causes of foundation movement here — which is exactly why crawl space encapsulation is a common need here.
