Epoxy doesn't make anything moisture proof. It can however greatly retard the rate of moisture penetration. However, it requires several coats to provide an effective moisture barrier - however, some is better than none. I don't pound plugs. I drill slightly oversize holes - such that the plug will simply drop right in - or maybe with a gentle push - pour in enough epoxy, and push in plug with epoxy overflowing out. The overflow epoxy can be directed into the next holes to be filled, and so on. I would not be surprised to find that such a plugged block is stronger than a new block.
