Crack stitching is a method of strengthening masonry walls so as to tie and reinforce masonry across the fracture region. That is why high tensile stainless steel helical bars are often used. Twistfix bars are used to stitch across the gap to strengthen brick and stone masonry walls.
There is a particular way the helical bars are used for the purpose of crack stitching. For instance, if the crack stitching is to be carried for brickwork, then the helical bars are put into slots which are cut into mortar bed joints. This is done primarily to ensure that the crack repairs are fully concealed to leave the wall looking untouched. When the reinforcement is applied to rendered walls there is no need to fix them into the mortar as slots can simply be cut through the masonry units, tying them together for a really strong repair.
Over many years, crack stitching as a part of masonry repair work has proven to be the best solution for dealing with cracked walls. The presence of handy crack stitching kits have also made it simple for homeowners to do the job themselves if they have a little building knowledge. For builders the masonry crack repair kit offers an income stream usually reserved for specialized contractors. The kit contains crack stitching bars and masonry repair grout designed for bonding the helical bars perfectly into masonry walls built of bricks, blocks or stone.
Remember, stitching a small crack as soon as it is found saves the need for more stitching at a later date when the crack has become larger. The idea is to opt for a cost effective method that can deal with the problem easily to save significant costs in the long run..
