Introduction
Post fix anchors are typically present when a modification is installed into a structure. This could be due to a late change or as part of a refurbishment. These anchors have been used to attach structural elements to concrete and masonry for many years and recently the technology behind them has become increasingly complex. Additionally, they are used in temporary and enabling works, fixings for barriers, balconies and handrails and for providing fixings to restraint straps in domestic construction.
In response to this, we have developed a Technical Guidance Note that introduces post fix anchors in an attempt to provide some clarity around the multitude of options that can be presented to a designer required to specify anchors.
