Time for an update as promised. Seems now that the GC contacted another leveling contractor when a lesser known leveling product manufacturer came along promising his product would bond to the concrete slab containing the amazing moisture "blocking" additive. Further still, the sales person claimed that F1869 could be performed on the slab, contrary to what ASTM F1869 states!! Fortunately, the leveling contractor wisely walked away from the potential job knowing the high level of risk involved. In the meantime, time is running out fast to get this job done, and there's no one willing to risk a failure, knowing what danger lurks within the slab. Not to mention the specialty flooring contractor who knows better than putting his product over this ticking time bomb.
