When would I use epoxy anchors?
Epoxy is required in home building. Especially when attaching a wooden stud to an adjacent concrete wall. Architects and Engineers will usually specify a rod depth and that they are set with epoxy into the wall. The epoxy can be rolled onto the rod extensively and then placed into the hole. You usually allow the rod to set with the epoxy for 24 hours before attaching any hardware to the rods such as 2x4 pressure treated plates with 2 inch washer and nut. You can buy All-Thread rod that you simply cut to length. If you are concerned about the dust, then use an air compressor to blow out the hole prior to inserting the rod. When I added on a room to my house, it was specified that the rods must be epoxied into the hole. I used Loctite Metal/Concrete Epoxy.
