In a tongue and groove log joint a seal seating channel is formed in the base of the longitudinal groove and a resiliently flexible seal is seated in the seal seating channel. A slot may also be cut in the base to accommodate a reinforcing metal rod. In a butt joint in which a second log underlies the butting logs a seat is formed in the edge of the second log in alignment with the locking slots of the butt joint to receive an end of the locking pin. The seat locks the locking pin against longitudinal movement with respect to the second log. In a wall construction in which the logs of the adjoining walls are connected by an overlapping tenon joint, a first pair of elongated tubular cavities arranged one on each side of a first interface and a second pair of elongated tubular cavities arranged one on each side of a second interface. The tie members are located at each interface and are arranged with one lobe seated in one of the tubular cavities on one side of the interface and the other lobe seated in the tubular cavity on the other side of the interface.
