Converse to the epoxy requirements, when using Anchor All, there is no limit on how much larger the hole can be, as long as it provides at least the required 1/2” clearance in every direction. That may be true in absolute terms, but when using grout to bind to asphalt, this is a moot point -- even the weakest cement is stronger than any asphalt. So if you apply a impermeable epoxy coating to concrete that has either subsurface moisture or contains moisture with another barrier on the opposite side, subsequent temperature cycles can cause delamination or even substrate spalling. Anchoring Adhesives for Concrete Permanently set threaded rods, studs, and rebar in dry concrete with these two-part epoxies. No need to be 28 days old. In order to gain cracked concrete approvals, these anchors must be qualified through rigorous testing in accordance with ACI 355.2 (mechanical anchors) or ACI 355.4 (adhesive anchors). Chemical anchors (I prefer the simpler term ‘resin anchors’) exert no setting stresses in the base material so can be specified at closer edge and spacing distances in concrete and will usually develop the strongest anchorage in masonry materials – which are their main ‘Pros’. The other important factor to consider when determining the hole diameter is cost of the epoxy. Epoxy grout consists of epoxy resin, epoxy hardener and sand/aggregates.
