Moisture barrier system for earth-sheltered housing

Abstract

A moisture barrier system for earth-sheltered housing and similar earth-contacted surfaces includes a laminated construction of "Styrofoam" and polyvinylchloride film which is adhesively joined to all exterior surfaces of the housing which are covered by earth. The polyvinylchloride film is provided in sheet form and adjacent sheets are arranged with an overlapping joint of approximately four inches and adhesive sealant is applied to each surface of the joint. Adhesive sealant is used to mount the "Styrofoam" to the poured concrete walls of the housing structure and a similar sealant is used to apply the polyvinylchloride film to the "Styrofoam". At each entry location of pipes and conduits, a pair of conduit seal assemblies are located. Each seal assembly is arranged into two longitudinally split halves which define a central conduit passageway extending therethrough. The two halves are held together around the corresponding conduit by a steel band clamp. Each seal assembly has an enlarged base portion which is adhesively joined to the polyvinylchloride film and the conduit passageway is similarly coated with adhesive sealant to provide a water-tight construction around the conduit.
