Upon time of inspection, prior to injecting the epoxy, the licensed Deputy/Special Inspector will verify the holes for proper embedment depth and diameter according to the approved plan detail. Holes are typically drilled 1/8" larger than the rebar, rod, anchor, etc being inserted. The size and grade of the rebar, rod, or anchor will also be verified at time of inspection. The Inspector will also verify that the holes are blown and brushed clean prior to epoxy application for proper bonding of the epoxy. The type of epoxy and its expiration date will also be verified prior to application. The most common types of epoxy used are Simpson SET XP along with multiple makes of Hiliti brand epoxy. Your plans should state which type of epoxy is designated for your project. The Inspector is only required to be there after holes have been drilled and prior to injecting the epoxy.
