<p>Inserts are made from thin strips of material and no thicker in height than the thickness of the required horizontal joints in the brickwork or blockwork they are to be used with. They are made narrower and shorter than the bricks or blocks, and placed in the mortar on a wall, and bricks or blocks are pressed firmly on top of them until the insert is in full contact with the bricks or blocks above and below them causing all the mortar excel that required to form a level and even joint to be extruded. whereby a joint of equal thickness is created at all times, and because the width of the inserts is narrower than the bricks or blocks they are used with, they remain concealed. The wall appears similar to those erected by skilled tradesmen even when erected by unskilled labour. <IMAGE></p> |
