Laying and Pointing
Flintblocks are delivered to site by Pallet with or without crane offload. A full pallet of blocks equates to 8m² (80 Full size blocks) and has a gross weight in the order of 1.4 tonnes. Each block has an average weight of about 17kg. Blocks are laid in the traditional form but with tight 5mm bed and perpendicular mortar joints.
Once laid and the beds have stiffened, the desired pointing mix is made. Some are sand mortars of varying colours; others include sharp sand, lime and grit. A gauged mix is recommended for consistency. The mortar is pressed into the spaces between the flints and left slightly proud until it starts to go off. Any large gaps are filled with a piece of Galleting flint separately supplied with each consignment.
Once the pointing starts to change colour the cutting in begins. The bricklayer carefully cuts round each flint with a pointing knife to produce the desired effect, which can vary from site to site. Once completed the wall area is brushed with a stiff brush to remove any mortar from the flint faces.
The finished product is quite impressive. This panel is our sample for on site use to exhibit its use in a cavity wall situation. Viewing on site does expel any fears operatives may have on the use of the standard flint blocks and demonstrates our reveal block which eliminates the need for brick or stone quoins.
