Thanks Bill and Bob for responding to this, it is one of those things that brings me back to “where are the dead bodies”.

I believe there are only two that are approved. They would be the Simpson Strong Bolt and the Hilti TZ Quik Bolt.

 

The list has indeed shrunk.

 

The manufacturers are not standing by. It’s expensive and time consuming to do the cracked concrete test in an outside lab for all the various conditions according to the current ICC acceptance criteria.

I admittedly have not dug that far into appendix D and am seeking a quick answer from those who have.

 

An architect told me last week that on a project where anchoring equipment to a concrete slab the plan checker advised that wedge anchors were no longer allowed by ACI 318……….can this be possible?

 

I can’t imagine the manufacturers of mechanical anchors ($$$$$$$$) standing by while something like this got written into code.
