Crack Stitching
Cracking is a common problem with older brick and stone buildings.
If the cracking is significant, we recommend getting a structural engineer to determine the cause of the problem.
Once the cause has been determined and crack stitching has been confirmed as the solution, K&S Restorations can install the appropriate remedial crack stitching bars and repair the masonry or mortar back to its original state.
When any crack suddenly appears in a property, regardless of its size, it should be investigated immediately if just to add peace of mind that there is nothing structurally wrong.
In some cases, wall coverings, paint or render may obscure the extent of the cracking and damage making any cracks appear to be less serious than they actually are.
In the majority of cases small, hairline cracks in walls, ceilings and plaster can be a sign of simple expansion and contraction movement within the building caused by temperature, weather, settlement and age. If this is the case, then crack stitching is an unobtrusive and effective way to rectify the problem at a relatively low cost.
If the cracking is significant there may be a more serious problem, we would recommend taking records and measurements of cracking, this helps to determine the reason for cracking and severity of the problem.
Heritage Crack Stitching Perth
Crack stitching bars provide a permanent solution for masonry repairs and cracked wall reinforcement. Crack repair rods are simply and effectively grouted across cracks in walls to reconnect and strengthen masonry.
Stainless steel brick stitching ties have a tensile strength within the 1050-1200N/mm² band and a spiral twist that permits a degree of torsional yield within elastic limits.
The structural repair system integrates the axial strength and elasticity of the stainless-steel bars with the properties of WHO60® grout to enhance the tensile, shear and flexural capacity of masonry walls.
Anchored across fractures, the crack stitch ties progressively accumulate building loads and disperse them back into the structure to strengthen cracked walls. This effective masonry stitching repair provides resilience against further cracking with minimal cost and little disruption.
