Underfloor Systems

An under-floor system is designed to remove water from under the crawl space after it has already intruded into the crawl space.  If installed throughout the entire crawl space it can minimize the moisture under the home.  An under-floor system generally consists of 3” perforated drain line with Class II perm drain rock.  From this main line there will be finger trenches and then the under floor will be capped with a vapor barrier.
