Anchoring wood framing to stacked limestone

| Posted in General Discussion on
I’m trying to anchor wood framing to my foundation wall of stacked limestone. The framing will serve to help hold Comfortboard 80 mineral wool insulation and a plywood fascia to protect it.
The problem is, tapcons are useless and the only solution appears to be a glue-in stud. I see a website or two (Hilti and Simpson) that seems to have that, but before I commit to figuring out how that works or where to get them (it appears it’s pretty expensive), I thought I’d get a second opinion.
I suppose I could just dig ground-contact rated AC2 into the soil and attach the framing to the house sill beam, avoiding the wall entirely. Not crazy about that idea, but if it’s the best way to go, so be it.
Thoughts?

20+ yrs ago I had a job in an old small town commercial bldg. All brick. Record store expanded their space into the next bldg. The designer wanted a siding material up above the displays.
Soft red brick didn’t like tapcons to anchor the furring strips. They’d strip out easily without tightening the furring. Shooting Hilti anchors didn’t work either.
The Hilti rep I think suggested a drive in anchor if my memory serves……..but if not, you drilled a pilot hole in the furring big enough for the plastic sleeve to clear, and continued to drill into the soft brick the depth of the anchor…….
Man, it may have been over 30 yrs ago….
I thought we drove in the anchor but the example of what I show in the picture shows a screw head. If that’s the case, you tapped the anchor through the furring and into the hole in the brick then screwed the anchor tight.
Maybe you can find this example and try it. It held the furring well, siding with various sorts of displays and other crap.
