ABSTRACT:
The watertight decking is assembled from extruded panels to form a watertight deck assembly. First side, second side, and intermediate panels have complementary edges mating with other corresponding panels. One edge of the first side and intermediate panels has a drainage gutter and the tongue or groove of a tongue and groove connection, with mating second side and intermediate panel edges having the mating tongue or groove. A depending drip rail wedges tightly against the opposite gutter wall of the adjoining panel to prevent relative motion between the two, and also to prevent capillary flow of liquid across the underside of the panel where it could leak into the area below. Additional sealing may be provided along the tongue and groove joints. A second, lower wall opposite the upper wall defines a series of conduits therebetween, and also strengthens the panels and provides a finished appearance for the underside.
