ABSTRACT:
A flooring board assembly comprising a plurality of board parts, each board part having generally opposed tongue and groove formations thereon engageable with the groove and tongue formations, respectively, on an adjacent board part of the assembly. Each board part is further formed with a first notched surface below the tongue formation thereon and a second notched surface below the groove formation thereon. The corresponding first and second notched surfaces of any pair of adjacent board parts form a groove-like cavity upon engagement of the corresponding tongue and groove formations thereof. Each groove-like cavity is filled with a hot-melt resin which adheres to the corresponding first and second notched surfaces thereof. The corresponding first and second notched surfaces of each groove-like cavity cooperate to expand or contract said resin therewith in response to upward or downward flexure, respectively, of one of the corresponding pair of engaged board parts so as to conform the flooring board assembly to an uneven floor system.
