Why can't you use wedge anchors?


The short answer is that my approved permit plans call for epoxy
anchors. The long answer is that while I haven't checked the numbers,
I am under the impression that epoxy anchors are much stronger. I'm
in a seismic zone.

For shear loading, "hammer in" / wedge anchors are perfectly adequate

for uplift (tensile loading) wedge anchors are not ok, epoxy is the
way to go.
