A plastic or metal web is provided with upper and lower projecting truncated conical members with a surrounding edge band having a thickness equal to the conventional mortar joint between brick or block courses. It is placed on the last laid course with the downwardly extending members frictionally engaging within the apertures in the bricks or blocks. Mortar or other adhesive may be used if desired and the next course is then laid engaging the upwardly projecting members. The spacing of the projecting members is such that the bricks or blocks are aligned spaced and reinforced thus facilitating laying of the bricks or blocks.
