Anyone else out there heard from Hilti about no longer using their HDI to hang pipe from the bottom of cracked concrete in seismic categories C-F? We had a (the sky/pipe is falling) presentation from Hilti about using their new TZ Kwik Bolt instead of the HDI, HDI-P or powder drive pins. They leave you with the impression that all pipe supports must be changed to the TZ, they even sighted two projects in AZ where the contractors had to abandon the installed HDI's and reinstall the TZ.
I have been doing some research on their presentation and I don't think their claims will stand the light of day but I would like some other opinions. I would be glad to PM Hilti's power point presentation to any interested parties. I wonder if the marketing guru that got backflows required on Class 1 & 2 sprinkler systems went to work for Hilti?
