A block plank for building wooden walls, formed of a plurality of block planks (6, 7) located horizontally one above the other, of houses and other buildings is proposed which on its lower bearing face (8) has a wedge-shaped longitudinal slit (3) that tapers toward the heart (2) of the block plank (6, 7). The method of the invention for producing such block planks (6, 7) with a low wood moisture provides that the logs (1) used, before the drying operation, are provided with at least one longitudinal slit (3) extending as far as the heart (2) of the respective log (1); that the logs (1) are then dried in a drying chamber to a moisture content of less than 15%, preferably to a moisture content of 11%; and that the logs (1) are then sawn to the desired size of block plank.
