The invention relates to a floorboard for a flooring system comprising a plurality of mechanically connectable floorboards. The floorboard comprises a first connecting profile along a first side and a second connecting profile along a second side that is parallel to the first side. The first connecting profile is configured for locking engagement with the second connecting profile of another floorboard both horizontally and vertically. The first connecting profile comprises a protruding strip at the bottom face of the floorboard, the protruding strip terminating outwardly in a locking element projecting towards the top face of the floor board. The second connecting profile comprises an overhanging tongue delimiting at its bottom a recess for receiving the protruding strip, the recess comprising a locking groove configured for cooperating with the locking element so as to provide a horizontal locking effect. The first connecting profile comprises a tongue groove arranged above a stem portion of the protruding strip. The tongue groove is configured to accommodate the tip of the overhanging tongue so as to provide a vertical locking effect. The overhanging tongue comprises an upper contact surface and a lower contact surface that are inclined with respect to each other. Complementarily, the tongue groove is delimited by an upper delimiting surface and a lower delimiting surface. The upper and lower contact surface of the overhanging tongue are configured to be put into contact with the upper and lower delimiting surface, respectively, of the tongue groove.
