Thank you your urgently responsed.Refer to my previous mail, please submit for inspection report that CMC already inspected in the past and approved Times to laid the ceramic tile on wall. My concern that no any apply waterproof on floor but applied on wall. Why they don’t apply waterproof on floor and wall at the same time and run up to the wall prior laying ceramic tile.It may be leakage in the future. I would like you to submitted the PAST INSPECTION REPORT, IS IT ALREADY CHECKED AND APPROVED BY CMC OR NOT?
