Cracks in concrete can appear in buildings for several reasons, including moisture and thermal movement, ground settlement, vibrations or concrete corrosion. These cracks must be adequately repaired to preserve the life of the building. JCP, the specialist fixings division from Owlett-Jaton, offers an excellent crack stitching solution, which is growing in popularity year-on-year.
Crack stitching is a simple concrete crack repair method, which mends, stabilises and reinforces cracked walls and bricks. A mix of materials is used with a stitching bar fitted, which is then grouted around to rejoin and seal cracked components. It eliminates the need to rebuild costly walls and also helps to minimise the likelihood of further cracking.
The JCP crack stitch twist starter kit is a two part component system consisting of A2-304 stainless steel stitching bars and polymer reinforced cement-based anchor grout (a two part non-flammable, non-shrink, thixotropic cementitious grout).
The powder component of the grout is based on a Portland cement mix with high-quality graded silica sands plus a synergistic blend of admixtures. The liquid component is based on a styrene-butadiene co-polymer, which acts as the total gauging liquid. The grout is pumped into place using a mortar cartridge gun, offering an excellent bond to masonry and great compressive strength.
JCP’s crack stitching system is available separately and as a kit. It is a fast and cost-effective, easy to use, non-disruptive, versatile method, which offers a permanent repair. It requires no special skills for installation, making it ideal for small and big repairs and once installed, it is also invisible – helping to restore the appearance of the building.
