1. A tilt wall comprising a sealed abutment joint between two concrete wall panels, the wall comprising a first wall panel, a dual gasket assembly, and a second wall panel,
wherein the dual gasket assembly comprises an interior gasket, a support coupling, and a weather gasket,
the first and second panels each having a height and a thickness, and each having a first major face and an opposing second major face,
the first panel further having a first edge face, said first edge face being generally perpendicular to both the first major face and the opposing second major face of the first panel; the first edge face having a first edge face length that is the height of the first panel and a first edge face width that is the thickness of the first panel,
the second panel further having a second edge face, said second edge face being generally perpendicular to both the first major face and opposing second major face of the second panel; the second edge face having a second edge face length that is the height of the second panel and a second edge face width that is the thickness of the second panel,
wherein the first panel has metallic channel anchor forming an integral metallic channel in the first edge face, the integral metallic channel anchor being oriented such that the metallic channel in the first edge face is parallel to the first edge face length; and
wherein the support coupling for the dual gasket assembly is attached to the panel by the metallic channel,
the support coupling comprising a base, the base having a top surface and a bottom surface,
the top surface further having an interior gasket support and an exterior gasket support,
the bottom surface of the base having a contact area for stabilizing the support coupling on the edge face, the bottom surface further having an attachment area for attaching the support coupling to said metallic channel, the attachment area being at least one projection;
wherein the first and second wall panels as aligned adjacent to one another, such that the first major face of the first wall panel and the first major face of the second wall panel lie in the same first plane, and the opposing second major face of the first wall panel and the opposing second major face of the second wall panel lie in the same second plane, and the first and second planes form a set of parallel major face planes, and the first edge face of the first wall panel and the second edge face of the second wall panel also form a set of parallel edge face planes,
with the support coupling of the dual gasket assembly attached to the first edge face and positioned between the first edge face of the first wall panel and the second edge face of the second wall panel, within both the set of parallel major face planes and the set of parallel edge face planes,
the second edge face of the second wall panel positioned relative to the first wall panel a desired distance proximate the first edge face to form a desired breadth of the abutment joint between the edge faces;
the interior gasket is attached to the interior gasket support and the outer weather gasket is attached to the exterior gasket support, the interior gasket and the outer weather gasket in contact with and compressed against both the first edge face of the first panel and the second edge face of the second panel to seal the abutment joint between the said edge faces of the two panels.
