13.5" English Bond Solid Brick Wall
For roof spans of up to 18’ this construction types relies on a 12” deep concrete footing placed 4’6” below grade to support a 13.5” thick solid brick wall. Alternating heading and stretching bonds at each course are held in place by mortar joints no greater than ½” thick. Wooden floor joists are laid parallel to rafters and rest upon wooden wall plates that span the perimeter of the wall on piers projecting from the foundation wall or on the tops of tapering walls.
