Title: Air conditioning condensation drainage system

Abstract: An air-conditioning condensate drainage system for mounting to the roof membrane of the roof structure of buildings or for constructing directly onto the roof membrane of a building structure. The air-conditioning condensate drainage system has an isolation membrane having a bottom surface for assembly to a roof membrane. A pair of ridge structures are disposed in fixed relation with the isolation membrane and are disposed in spaced relation with one another and cooperate with the isolation membrane to define an air-conditioning condensate drainage channel between the spaced ridge structures. Each of the ridge structures has one or more ridge defining elements which is fixed to the isolation membrane and projects above the isolation membrane sufficiently to define a condensate drain channel therebetween. One or more upper membranes may be disposed in covering relation with the ridge defining elements and are conformed to suitable configuration by the ridge forming structures to define spaced condensate containment ridges. The upper membranes are also fixed to the upper surface of the isolation membrane to form an integral condensate drainage unit to conduct a/c drainage from a/c units to an in-roof mounted drain.
