Retro Flex Remedial Wall Tie
Retro Flex ties are manufactured from Grade 304 austenitic stainless steel. The 6mm diameter Retro Flex has a tensile strength in excess of 9.7kN. The manufacturing process produces very hard fins that are able to cut a thread into the hardest concrete, but maintains a very soft and flexible core. The near leaf fixing can be achieved by the use of Target Polyester Resin material or Bond Flex cementitious grout. Bulk mix epoxy resins are not recommended for normal installation as it has been noted that many of these resins are not reliable due to their accurate mixing requirements.
Where there is a need for a fire resistance in excess of 30 minutes only Bond Flex cementitious grout should be used.
