The support strength of drywall
I've been trying to hang a metal kitchen rack in my kitchen. However, I've discovered that underneath the drywall, I hit concrete. Solid, rebar filled concrete that destroys tapcon bits and concrete screws alike. I have an estimated thickness < .5-.75 inch drywall, and a maybe little air space between the back of the drywall and the concrete. I'm not certain the ratio of air-drywall, or if there is air at all. Holes in the drywall stop at almost exactly .75 inches deep.
Can I get 3/4 inch anchors and how much weight will the drywall with anchors hold?
