Why does it show online that the HKD anchor is only suitable for use in uncracked concrete? Can I not use it in cracked concrete?
The HKD is suitable for use in cracked concrete where the application qualifies as a redundant non-structural fastening system. In this context, redundancy means that the supported system incorporates multiple fixing points and has sufficient capacity and stiffness to redistribute the load to adjacent fixing points in the event of excessive displacement or loss of performance of an individual fixing. Where the application relies on a single fixing point for stability, an anchor with a full approval for cracked concrete should be specified instead.
