Joint seal for panels used to form sectional tanks

A sealing mechanism to seal between a first tank panel and a second tank panel that are securable together to form at least a portion of a tank, the sealing mechanism comprising:

• an elastomeric seal having a lateral flange and a longitudinal ridge positioned along an outer edge of the lateral flange, the longitudinal ridge perpendicular to the lateral flange;
• and
• a retainer securable to an inner face of the first tank panel and adjacent a side surface of the first tank panel, the side surface being at an angle to the inner face and extending between the inner face and an outer surface of the first tank panel;
• wherein the retainer fixes the elastomeric seal to the inner face of the first panel along a side edge thereof by compressing the lateral flange against the inner face of the first tank panel, with the longitudinal ridge of the elastomeric seal abutting a side surface of the retainer;
• wherein the retainer, when secured, extends along the side edge of the first tank panel and extends outwardly from the side edge terminating at a position laterally exterior to the side surface, the retainer limiting the displacement of the elastomeric seal in an inward direction toward a central portion of the tank formed at least partially from the first and second tank panels when the elastomeric seal is compressed by the securement of the second tank panel to the side surface of the first tank pane;
• and
• wherein the retainer has a concave portion, the elastomeric seal at least partially received within the concave portion.

• wherein the lateral flange of the elastomeric seal is compressed between the longitudinal flange of the retainer and the inner face of the first tank panel when the retainer and the elastomeric seal are secured to the first tank panel such that the retainer fixes the elastomeric seal in a position that is parallel to a longitudinal axis of the side surface of the first tank panel, and wherein the retainer, when secured, extends along the side edge of the first tank panel and outwardly from the side edge, terminating at a position laterally exterior to the side surface;
• and
• wherein the retainer limits the displacement of the elastomeric seal in an inward direction toward a central portion, of the tank at least partially formed from the first and second tank panels, when the elastomeric seal is compressed by securement of the second tank panel to the side surface of the first tank panel.
