Crack Repairs
Cracks in masonry can arise for a variety of reasons including ground movements, external pressures (on retaining walls) and wall tie failure. They can manifest themselves as stepped cracks along the mortar joints or in some instances will cut straight through the brick or stone. The most common repair involves embedding stainless steel helical bars in the bed joints, to re-establish the structural integrity. The process generally involves raking out the bed joint to a depth of 5 to 6 cm (approximately two inches) followed by the injection of a
Cracks in masonry can arise for a variety of reasons including ground movements, external pressures (on retaining walls) and wall tie failure. They can manifest themselves as stepped cracks along the mortar joints or in some instances will cut straight through the brick or stone. The most common repair involves embedding stainless steel helical bars in the bed joints, to re-establish the structural integrity. The process generally involves raking out the bed joint to a depth of 5 to 6 cm (approximately two inches) followed by the injection of a cementitious grout or polyester resin. The reinforcing bar is pressed into the grout/resin and when cured, re-pointing with cement or lime mortar in keeping with the original masonry, can take place. Some filling of cracked bricks may be required to ensure water does not enter the structure; a sealer is then often applied across the wider area for general weatherproofing. Listed below are a range of Stitch Repair Kits, Packages of Stainless Helical Bars and Grouts/Resins.
Elsewhere on this website, you will find our 230 mm C-Tec dust-free cutting cowl and the Arbortech Masonry Saw both of which will permit mortar joint removal down to 6 cm. We also offer the Quikpoint electric repointing system (can be mains or battery-powered) and the Pointmaster jointing tool for making good the finished joints, along with spray and brush-applied Weatherproofing treatments.
