Failed concrete during pull test on anchor bolt

Hi Andrew,

Hilti does not have a published method, however, typically, engineers will re-evaluate and one possible option is to core out the existing anchor bolt and install a new adhesive anchor. If you decide to core out existing anchor bolts, it is important to determine which adhesive anchor is suitable for cored hole conditions. Here is the link to the Hilti Product Technical Guide for Anchor Fastening. Please refer to the Anchor Selection Guide on page 8 for suitable adhesive anchors.

Regards,
Paris

How Pull Out Testing Works

Why Conduct Pull Out Testing?

Do your fixings need annual testing? Will the anchors take the proposed loads? Does the fall arrest system meet current legislation? – these are just some of the questions asked. Our pull out testing service will provide the answers.

Normally performed to establish the load capacity strength of fixings that have been installed or fitted into walls, slabs, soffits etc, our pull out tests are vital for commercial buildings, railways, airports or domestic situations.

There are many factors that can affect the strength and durability of eyebolts, anchor bolts, scaffold ties, stud anchors, resin bolts and safety wires, so it is vital that they are regularly checked tested and certified. This is especially the case when visual inspection is just not enough. This is where Pull Out Testing UK comes in.
