Stooled Cills – To prevent cracking after installation only the ends and cill joints should be bedded on mortar. The joint below should be left open and pointed up after the brickwork is finished. Slip Cills – Should be fully bedded down on mortar Decorative Heads – Should be used in conjunction with a suitable load-bearing lintel. To reduce the risk of cracking, the Head should be fully bedded down on mortar along the entire length of the load-bearing lintel.This ensures that any load above the Head is fully and equally distributed on the load-bearing lintel. |
Movement Joints – Vertical movement joints should occur at intervals of 6 meters in long lengths of walling.
Mortar Recommendations – Premixed coloured mortars are available containing lime, we would recommend that a grade of 1:1:6 (Cement: Lime: Washed Sand) is used as this will give a lower permeability and give a greater resistance to rain penetration. In addition, voids and hairline cracks, which may develop in lime mortars, tend to seal themselves over a period of time.
