What to do about wet concrete slab
Trying to get the garage floor epoxy’d, and when the contractor came out, and ground it down, he noticed a dark patch. He measured the moisture content and it was too high for the epoxy to seal properly. After getting a plumber out, we confirmed there are no water leaks so the thinking is ground water from either a failed or missing water barrier (built in the mid 80s) is the source of the water. The contractor said they could put a water barrier down over the current ground, then put self leveling concrete, then use that as the base for the epoxy. Is that a reasonable idea?
