How to choose a crack repair method and material
General principle - cut out the cracks with a saw, Router, masonry grinder, or Allsaw, to form square edged slots, and remove all dust and debris. Avoid V shaped slots - the repair will be much weaker.
Repair Thickness - the more material that we can put in to the repair, in terms of width and depth, the better it will be able to accommodate natural movements caused by changing temperatures and therefore the better it will last.
Caution - Always consult a Structural Engineer and the building's Insurers before proceeding.
