We have 2hr fire barrier masonry walls and some concrete walls with random 1/8" linear cracks that vary from about 4 to 10 ft in length. We were asked by the surveyor to I quote "Install listed firestopping system to protect the penetration". Now in my opinion I can as well patch it with cement mix. Is there any specific UL S...

I was wondering if it was possible to import a RAM Elements Baseplate Design into the Hilti PROFIS Software and if so, how I would go about doing that. I have uploaded a RAM Elements DXF file as an example for a test run if needed since I was not able to upload a RAM Elements file. Thanks for the help.

We are utilizing ASTM F1554 grade 36 threaded rods with Hilti's HIT-HY 270 adhesive in grouted masonry CMU walls. Would hot-dip galvanizing the threaded rods have any effective on the capacity of the anchor adhesive?

we have around 45 of such rooms requiring sealing floor tiles and ceiling tiles as shared in attached pictures. room integrity test successfully in these rooms (hold time of 10mins) and there should not be any leakages through floor and ceiling tiles. Nozzle is only present in Room void and that is why sealing of floor and cei...

I was trying to download an anchor file which I designed on Hilti but I am not able to find it. Could you please help me with it?

Does Hilti have any guidance for anchors installed in close proximity to a concrete cold joint? The specific application we are considering is a post-installed anchor in a thickened slab adjacent to a blockout for a column. Once the diamond is filled with concrete, should the concrete cold joint be considered an edge for anc...

I have a 2hr conc floor slab (waffle slab, not deck) with multiple existing penetrations from previously removed pipes. I need an installation similar to UL-AJ-00-70 but from below. No access from floor above.

What size Drill Bit do I use on a M20 Concrete Wedge Anchor Bolt

I am trying to find out the width and depth that FS-One Max intumescent firestop caulk can fill?

In doing a anchorage calculation in Hilti Profis, I notice that an anchor design I have will pass checks using cracked concrete but will not pass checks using uncracked concrete. Upon examination of the detailed reports, it appears that different phi factors are used between the two sets of calculations. Can you provide an e...
