Our crew removed and disposed of the existing insulation, then going over the entire area with a mold treatment to get rid of a prevent existing and future mold and mildew particles. A 4″ trench was dug around the perimeter of the home, connected to the preexisting sump pump unit to remove any and all water from the crawl space and foundation. A demple mat along with a 20 ml liner were lined against the earth of the crawl space to create a barrier between the ground and the future encapsulated crawl space. The wall were then lined with 2″ of closed cell foam, sealing the liner and all foundation vents. The rim joists were insulated with 4″ of open cell foam, sealing off any air leaks and creating an air tight space, coupled with the crawl space encapsulation door.
