Bricklayer by trade however not being in the trade for years and I mean years, and things have changed to how we used to do it. I have dusted off my tools to build myself a garage. Its single skin 73mm bricks and need to put some piers in. Size approximately 5.2m X 3.2m. How many piers should I put in, one on the back and two along the side? construction of the piers should I just put block on block with mesh tied across into the brickwork to form a pier or cut closures in the brickwork to construct a one brick pier?
