Pure epoxy is typically just an epoxy resin and a hardener, and its slow cure rate makes it prone to sagging if it is used for overhead applications. But pure epoxy is ideal for “downward installations” (shown) of an anchor bolt in dry concrete, yielding best-in-class strength. As in all cases, the holes has to be drilled and then cleaned out of concrete dust that may defeat the bonding power of the epoxy.
