Tongue and groove board including a water drainage system

Abstract

A tongue and grove board has a first surface and a second surface, a first longitudinal edge and a second longitudinal edge and a first transverse edge and a second transverse edge. The first longitudinal edge has a first longitudinal lip and a second longitudinal lip cooperating to form a longitudinal groove therebetween, and the second longitudinal edge has a longitudinal tongue disposed therealong. The board further includes at least one notch disposed in the first longitudinal edge, the at least one notch extending perpendicular to the longitudinal edge, through the first surface and the first lip and partially into the second lip. The at least one notch has a depth at the first surface which is greater than the depth of the groove. The width of the longitudinal tongue is greater than the depth of the longitudinal groove, such that, when the longitudinal groove of the tongue and groove board is interfaced with a longitudinal tongue of an adjacent tongue and groove board, a drain path is formed between the boards, the drain path including the at least one notch in the first longitudinal edge.
