The upper side of each log includes a longitudinally extending, generally vertical abutment surface located between the inner and outer sides of the log and a longitudinally extending inclined surface portion adjoining the abutment surface and sloping downwardly therefrom toward and adjoining the outer side of the log. Respective longitudinally extending filler panels are located between the upper side of each log and the lower side of the next higher log, with the filler panels being positioned against the vertically extending abutment surface on the upper side of the log for filling any longitudinal spaces between adjacent logs. A hardenable filler material is located between the upper side of each log and the lower side of the next higher log and covering the outer side of the filler panel located therebetween to provide a seal between adjacent logs to prevent the passage of water and air through the wall. ## Claims ### Claim 1 A building wall comprising a plurality of logs arranged generally parallel, one above
