1. A water drainage duct for draining water from a dual gasket assembly, wherein the dual gasket assembly is suitable for sealing an abutment joint between two wall panels, the dual gasket assembly comprising a support coupling, a compressible interior gasket, and a compressible weather gasket, with the support coupling comprising a base, the base having a bottom surface and a top surface,
the bottom surface of the base having a contact area for stabilizing the support coupling on an edge face of one of the two wall panels, the support coupling further having an attachment area for attaching the support coupling to said edge face,
the top surface of the base having an interior gasket support and an exterior gasket support, the top surface further having at least one gutter channel for directing water, the interior gasket support and the exterior gasket support separated by said at least one gutter channel, with the compressible interior gasket attached to the interior gasket support and the compressible weather gasket attached to the exterior gasket support;
the water drainage duct comprising a body having an attachment accessory for attachment to the support coupling of a dual gasket assembly, the body further having:
a water collection area,
a water drainage channel, and
a compressible gasket having an exterior port in a first wall, wherein said water drainage channel has a discharge exit in a second wall of said compressible gasket, said discharge exit being in fluid communication with said exterior port in said compressible gasket, and
wherein the water collection area is in fluid communication with the exterior port in the compressible gasket via the water drainage channel and through the first and second walls of the compressible gasket to allow water to move by gravity from the water collection area to and through the exterior port.
