CONTROL JOINTS
Should extend for the full height of the wall and be spaced at a maximum distance of 6 metres apart where walls are not interrupted by full height doorways or window openings (Refer Australian Standards). STANDARDS
All concrete brickwork is manufactured to AS2733 and laying practices should conform with AS3700. Mortar should be accurately batched and conform to AS123 and AS3700.
JOINT REINFORCEMENTS
Masonry mesh is recommended at height intervals of 600mm, and in the two courses above and below all openings. Lap mesh at least 150mm at all joints and intersections, except at control joints where a slip joint must be provided.
GENERAL GUIDELINES
All concrete brickwork should be laid dry, so covering on site is recommended. Whenever work is stopped, the tops of walls should be covered to prevent moisture entering the cavity. All mortar joints should be allowed to set to 'thumb print' hardness before tooling. Brush away excess mortar with a semi - stiff brush at the end of each day's work.
CLEANING
Care should be taken to keep bricks/blocks as clean as possible during laying . A weak acid mixture is recommended for cleaning down at no stronger than 1 part in 15 parts water. Walls should be wet thoroughly before application and washed thoroughly with clean water after application, high pressure water is not recommended.
ORDERING
C&M Stone and Austral products are manufactured from natural materials and will vary in colour and texture from batch to batch. All products must be ordered at the one time to ensure that they are supplied from the same batch.
Product should be blended from different pallets to ensure an even mix of colour throughout any given wall. |
