Abstract: A concrete block includes a top surface including one or more regions having a higher surface height that is then precision ground to the desired height. The one or more regions having a greater height may include a tapered front face of between 30 to 60°. A recess or pocket may also be provided in the top surface of the block in front of the precision ground higher height adjustment pads. One or more high-speed mortar/adhesive applicators includes a mortar/adhesive holding device, for storing a quantity of mortar/adhesive as well as a powered mortar/adhesive applicator, for moving the mortar/adhesive stored in the holding device to one or more applicator devices. The one or more mortar/adhesive applicator devices include an extruder nozzle surrounded by a generally “U” shaped pivoting channel element, for establishing at least the width of a bead of mortar/adhesive being applied to a surface of an object.
