Which anchor is the best option for gasbeton?

Thanks for the query. Since, Gasbeton is considered to be low compressive strength material, HILTI has HRD anchor approved to be used in AAC blocks which may easily take up this load depending on compressive strength of the base material , however, you may also need to install a base plate to fix/install any element therein. You may drop-in here or reach out to local HILTI engineer to assist you through helpline number.
