Mix five parts sand to one part cement, adding enough water to get a stiff consistency. Check the level of the site before spreading the first layer of mortar, compensating for any changes by adding more mortar. Use the spirit level to mark the outer edge of the barbecue in the cement. This provides a straight guideline for laying the first course of bricks. When the first layer of bricks is laid, check the level again, making sure that the corners are at right angles.
If you think the structure is not as sturdy as it should be, insert a metal tie into the mortar to join the angles of the walls, especially to the central wall if going for the two part build. As you build more layers, insert these as often as you need.
Now start laying the extra layers of bricks, beginning at the corners. Stagger the vertical joints alternately to the width of a half brick. Use a spirit level to check that each of the barbecue’s corners is vertically straight. Check from all angles to ensure the finished structure is square. When five courses are complete at each corner, use a length of wood and the spirit level to check that the two sides are even.
