Because of the method of installation it is not possible to perform random, non-destructive site testing. Bond strengths can, however, be checked prior to the full installation program. An overlong Cem Flex can be installed as normal leaving a short length (50-75mm) proud of the surface.
A Target Load Test Unit can then be used to determine the tensile loading. The full cure time for the Bond Flex XL grout is 28 days, but limited testing can generally be performed after 24 to 48 hours. To check the flow of Bond Flex XL grout into any voids required destructive testing methods and is normally only performed in critical conditions.
