Heavy objects (over 100 lbs) cannot sit on any foam bottom floating floor for an extended period of time (more than 12 hours).
Prior to installation, make sure there is no water leaks or under-concrete water seepage, as no floor should be installed in any room if moisture penetration is suspected. The area must remain dry.
Production Time is usually 2-4 business days, plus transit time. (Transit time is determined by the shipping company)
