Our Strucsol HS grout has been used in the repair of listed buildings for many years and is tried, tested and approve by structural engineers for use. This stitching kit (also referred to as a heli bar kit) contains everything you'll need to complete your crack stitch repair.\u003c\/p\u003e\n\u003ch2\u003eWhy use grout instead of resin?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMore time to work:\u003c\/strong\u003e Grout has a slightly longer set time, meaning if you are new to crack stitching, you have much more time to work with it- the initial set time can be up to 1 hour  (depending on the ambient temperature, hotter days means it will set faster). \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMore durable: \u003c\/strong\u003eOur grout is non shrink and will actually expand very nominally, meaning the grout and helical bar will be bonded extremely well into the bed joint- providing a much more permanent repair. Most resins (except for EASF resin and pure epoxy resin) shrink as they set and whilst they do still work for the job, they are not the strongest form of the repair. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChoice of consistency:\u003c\/strong\u003e When mixing the grout, you get a lot more choice over how smooth\/thick you would like the mixture to be. Additional water can be added if required. \u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEase of use and neater: \u003c\/strong\u003ea grout gun can hold more volume than a resin tube, meaning less stopping and changing resin tubes as you go along. It is also much neater to apply given that you don't have to work as quickly as you would with resin. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKit contains:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ex1 tub of Strucsol High Strength grout\u003c\/li\u003e\n\u003cli\u003ex1 Grout applicator gun\u003c\/li\u003e\n\u003cli\u003ex1 Additional stainless steel nozzle for improved reliability and application\u003c\/li\u003e\n\u003cli\u003ex1 Mixing Whisk\u003c\/li\u003e\n\u003cli\u003ex10pcs Strucsol Stainless Steel Helical Bar\u003c\/li\u003e\n\u003cli\u003ex1 Pointing trowel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCrack stitch repair process\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUsing a mortar raking blade of a 4 1\/2inch angle grinder (available separately) is equally effective and much cheaper in small volume.
