Dealing with redundant cast-in channels in close proximity to post-fixed anchors
Here, brick support specialist, Ancon, provides details of how redundant cast-in channels should be treated when located in close proximity to post-fixed anchors.
This information was compiled by the Ancon Technical Services Team, who are available to answer any Ancon product related enquiry. This guidance is based on using Ancon cast-in channels 38/17 or 30/20. Anchors that are greater than 100mm away from redundant cast-in channels can be designed in the normal way, treating the cast-in channels as the concrete edge.
For applications where the redundant channel is at least 50mm above the new post-fixed anchor.
For applications where the redundant channel is less than 50mm above the new post-fixed anchor.
In such applications, fill the cast-in channel locally (min 100mm) using Epoxy Putty and use a bolt with 20mm greater embedment depth, for example:
- M12 FBNII 12/30 becomes FBNII 12/50
- M12 FAZII 12/30 becomes FAZII 12/50
It is NOT RECOMMENDED to install a new post-fixed anchor in applications where the redundant cast-in channel is to be less than 50mm below the new post-fixed anchor. Please contact Ancon Technical Services with details of your brick support application.
