New from structural repair specialists Helifix, the Concrete Crack Injection Repair Kit is a low viscosity, fast curing epoxy sealing system for repairing cracks in concrete. Easy to use, the kit contains the necessary components, materials and instructions for an efficient and reliable crack repair that will cure in around 12 hours to be as strong as the concrete.
The kit is suitable for repairing cracks from 0.2mm to 6mm wide. It is equally effective in both vertical and horizontal cracks in walls, columns, beams, floors, slabs or lintels. The main components are CapSeal, a rapid cure thixotropic injection port adhesive and crack surface sealer, and CrackFix, a low viscosity, 100% solids epoxy. Both are convenient mix-in-the-nozzle cartridge systems that will fit a standard caulking gun, the only item the user needs to provide.
With vertical cracks, injection ports are inserted along the crack and its surface is then sealed with CapSeal. Once this has cured the CrackFix resin, which conforms to ASTM C-881, is injected into the ports in sequence until the crack is filled. With horizontal cracks, the CapSeal and ports may not be required and the CrackFix resin can be gravity fed into the crack. Wherever the crack, if it goes right through the substrate then both sides of the crack will need to be sealed.
John Heseltine, Helifix Technical Manager, said,
The new Helifix Crack Injection Kit is very simple to use and provides an extremely effective means of repairing cracks in concrete in any situation where reinforcement corrosion is not an issue. The kit contains all the materials needed to undertake a reliable, high bond, high strength long term crack repair.
