Most Texas homes are made on whether slab and have crawl spaces under them. Houses with slab foundations normally have concrete put on the top of the plastic moisture barrier. This limits the infiltration of moisture in to the thermal envelope of the home. Homes with crawl spaces, meanwhile, have a moisture barrier within their crawl spaces.
