Re-pointing is carried out once the existing mortar joints have broken down and started to crumble, causing holes in the brickwork which can lead to structural damage and cracking.
A combination of extreme weather conditions, excess moisture (often from sprinklers or watering systems) and a weak lime mortar mix causes masonry work and mortar to break down (fret) and fall out . Both bricks and mortar are subject to "fretting" or crumbling. Our teams use a mortar mix as specified by Australian Standards and are experts at matching the existing mortar colour and joint as closely as possible. Procedure:The remaining joints are ground out to a depth of 10-20mm using a vacuum system. Guns are used to inject new mortar into the brick joints, which are then finished to match the existing style as closely as possible. There are a couple of different methods of applying mortar between the bricks. Our teams have been trained to use guns to inject the mortar as opposed to using a trowel, as we have found this is the most efficient method and provides the neatest finish!
There are a number of possible "joint" finishes. Please see our "Joints" section under FAQ's for a complete description! |
