Summary: Learn how to build an exterior block screen, build the piers and lay the screen blocks.
Constructing block screens involves the tools and techniques used in bricklaying, but are modified to suit the block size, shape and use. If building a screen higher than 600mm (2ft) it will need to be reinforced vertically with 16mm (5/8in) steel rods and galvanised-mesh strips horizontally. The screen will also need to be reinforced with piers no more than 3m (9ft 9in) apart.
Lay the second course of screen blocks between the first two piers ensuring the vertical joints line up perfectly.
Coping slabs should be laid on top of the piers and along the top of the screen.
