Commercial meat and perishable product refrigeration buildings commonly suffer from infiltration of moisture which normally occurs at the roof/wall junction where the roof meets the walls. Warm moist outside air is drawn into the cooler because of the lower pressure therein and once inside, forms ice which lowers the cooler temperature and causes freezer burn. By removing the building roof, and installing a moisture proof 40-50 mil thick sheet polymer membrane onto the cooler wall panels, over the top sill plate and the top header ledger board then welding it at the roof perimeter to the roofing membrane, an impermeable seal can be formed. To ensure the unitary integrity of the system, a flexible polymer mastic is trawled onto the wall panels before the membrane is affixed and a double sealing strip is screwed into the membrane though the mastic and into the wall panels.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is as follows: 1. A method of retarding vapor intrusion into a building comprising the steps of: 1. removing a roof structure of said building; 2. applying a water resistant, synthetic high tack mastic to all wall panels and all peripheral vertical roof supports on the areas that contact said roof structure; 3. applying a first water insoluble caulking strip in a ring about said building on an interior surface of said wall panels; 4. installing a first membrane such that a first edge of said first membrane overlaps said first caulking strip and said first membrane resides atop said applied synthetic mastic; 5. affixing said first edge of said first membrane to said wall panels with mechanical fasteners that compress a double sealing strip means on said first membrane, adjacent to said first edge and atop said first caulking strip; 6. pressure rolling said first membrane into said mastic to eliminate air pockets and improve adhesion; 7. replacing said roof structure; 8. folding said first membrane onto a top surface of said roof structure; 9. affixing said first membrane to said top surface of said roof structure with at least one mechanical fastener and polymer wall membrane securement means; 10. installing a seam sealed unitary second membrane over said roof and overlapping said second membrane onto the exposed roof sections of said second membrane; 11. seam seal said second membrane to said first membrane so as to form a unitary membrane seal about said roof structure. 2. The method of retarding vapor intrusion into a building of claim 1 further comprising the following sequential steps after step 11; 12. installing a seam sealed unitary third membrane under and adjacent to a bottom surface of a floor slab of said building, all side surfaces of said building floor slab, and partially up onto an interior surface of said wall panels of said building; 13. applying a second water insoluble caulking strip in a ring about said building on said interior surface of said wall panels; 14. affixing said third membrane to said wall panels with mechanical fasteners that compress a double sealing strip means residing atop said first membrane, and said second caulking strip. 3. The method of retarding vapor intrusion into a building of claim 1 further comprising the following sequential steps after step 11; 12. installing a seam sealed unitary third membrane adjacent to a bottom surface of a floor slab of said building, all side surfaces of said building floor slab, an internal surface of said foundation wall, between said foundation wall and said wall and partially up onto an exterior surface of said wall panels of said building; 13. applying a second water insoluble caulking strip in a ring about said building on said exterior surface of said wall panels; 14. affixing said third membrane to said wall panels with mechanical fasteners that compress a double sealing strip means residing atop said first membrane, and said second caulking strip. 4. The method of retarding vapor intrusion into a building of claim 1 wherein said membranes are seamless, planar, alkaline resistant, UV resistant, flexible, scrim reinforced thermoplastic geomembranes, and wherein said mastic is a high tack, water resistant, trowelable synthetic rubber mastic sealant, and wherein said caulking is a self leveling, easy flowing, high tack strength, non crazing, water insoluble, UV resistant urethane compound silicone caulking, and wherein said a membrane double sealing strip means is a planar strip having a beaded first and second elongated sealing edge, and wherein said mechanical fasteners are corrosion resistant screws, and wherein said membrane securement means are polymer plates with teeth extending normally from a bottom surface thereof. 5. A seal for minimizing vapor intrusion into a building between a building roof, a building wall, vertical roof support members, building floor slab, and building foundation wall comprised of: a seamless, planar, alkaline resistant, UV resistant, flexible, scrim reinforced thermoplastic roof geomembrane; a seamless, planar, alkaline resistant, UV resistant, flexible, scrim reinforced thermoplastic wall geomembrane; a high tack, water resistant, trowelable synthetic rubber mastic sealant; a self leveling, easy flowing, high tack strength, non crazing, water insoluble, UV resistant urethane compound silicone caulking; a geomembrane double sealing strip means; at least one corrosion resistant mechanical fastener; and at least one polymer wall membrane securement means; wherein a first edge of said wall geomembrane is secured to an inside surface of said wall by at least one said mechanical fastener passing through said double sealing strip means and said caulking which is sandwiched between said wall and said wall geomembrane, and wherein a second edge of said wall geomembrane is secured to an exterior surface of said roof by at least one said mechanical fastener passing through said wall membrane securement means residing atop at least one layer of said wall geomembrane, and wherein said wall geomembrane resides between said roof and said vertical roof support members as well as between said wall and said roof; and wherein said mastic sealant resides between said wall geomembrane and said wall and between said wall geomembrane and said vertical roof support members, and wherein said roof geomembrane extends over said wall geomembrane and said wall membrane securement means and said geomembranes are seam sealed so as to form a unitary seal between said wall and said roof of a building. 6. The seal of claim 5 wherein said roof geomembrane and said wall geomembrane each have a thickness of at least 40 mil. 7. The seal of claim 5 wherein said wall geomembrane is corner cut and double wrapped onto said roof at corners of said roof. 8. The seal of claim 5 further comprising a unitary floor geomembrane that resides adjacent to a bottom surface of said floor slab of said building, all side surfaces of said building floor slab, and partially up onto said walls of said building. 9. The seal of claim 8 wherein said floor geomembrane has a thickness of at least 40 mil. 10. The seal of claim 9 further comprising: a self leveling, easy flowing, high tack strength, non crazing, water insoluble, UV resistant urethane compound silicone caulking; a geomembrane double sealing strip means; at least one corrosion resistant mechanical fastener; wherein said floor geomembrance is affixed to said walls by at least one said mechanical fastener passing through said double sealing strip means, at least one layer of said floor geomembrane and said caulking which is sandwiched between said wall and said floor geomembrane. 11. The seal of claim 10 wherein said floor geomembrane is corner cut and double wrapped onto said walls at internal corners of said walls. 12. The seal of claim 10 wherein said unitary floor geomembrane also resides adjacent to an internal surface of said foundation wall and between said foundation wall and said wall. 13. The seal of claim 12 wherein said floor geomembrane is diagonally corner cut and double wrapped onto external corners of said walls.
