When a demolition team tore down a gymnasium containing PREMOULDED MEMBRANE VAPOR SEAL WITH PLASMATIC CORE (PMPC) at Ursilane College on the east side of Cleveland, Ohio, they witnessed a key feature of the product – its incredible durability. While demolishing the building, the workers found that the PMPC, placed below the building's concrete foundation in 1973, was still intact - looking as if it had been placed this year: solid, no cracks, with its plastic release sheet still intact. This shows how PMPC is the premier vaporproofing and waterproofing membrane on the market.
PMPC is a patented (#US 7,179,761), seven-ply, weather-coated, permanently bonded, semi-flexible vaporproofing/waterproofing membrane. It is composed of an exclusive plasmatic core suspended mid-point between two layers of a homogeneous, bituminous material, and then sealed under heat and pressure between liners of asphalt-impregnated felt and a glass-mat liner. An asphalt weather coat is applied to the glass-mat liner and then covered with a polyethylene anti-stick sheet.
PMPC provides a positive, easy-to-install, economical, true vaporproofing and waterproofing system for horizontal applications. Properly applied, it stops moisture migration in footings, concrete floors, and structural slabs. PREMOULDED MEMBRANE VAPOR SEAL WITH PLASMATIC CORE is both waterproof and vaporproof.
Among its unique features and as demonstrated in its longevity in the Ursilane College gymnasium, is the built-in protection course, which resists jobsite puncturing and the abrasive action of concrete placement. The exclusive PLASMATIC CORE also adds flexibility, greater tensile strength, and excellent handling characteristics, in addition to providing unequalled vapor barrier properties.
PMPC's longevity and durability makes it the most complete waterproofing membrane and vapor barrier in the market. View our entire line of quality vapor barriers.
