Hi, I'm new to this so please forgive me if as I have no idea how all this work... We remolded our Houston home (built in 1968) this past year. A complete remodel, we ripped out walls, the kitchen and rebuilt all new cabinets and added new flooring throughout entryway, office, kitchen, breakfast area and living room. Open concept with beautiful large hardwood looking porcelain tile planks in January 2019. Also on the first floor next to these rooms is a master bath with porcelain tiles 12X12 and bedroom with carpet as well as a dinning room with hard wood floors.. all of these rooms are just fine. A few weeks after the install we noticed water coming up through the grout, several puddles, along with white powder and it just kept spreading. We called our floor company who really had no idea what it was or what to do. We call several concrete slab companies who told us the water table in the Houston area has been up since Hurricane Harvey and our house was built with no moister barrier. We were told that we needed gutters and to change our landscaping that there was most likely water under our house. We called plumbers and there is no leak, we have added gutters. The weather has dried up and we have been without rain for well over a month now. Side note...Here is what I noticed when the original tile 12X12 porcelain tile floor was ripped out, mold smell, damp floors and some areas of wetness. The floor company who installed put down a leveling compound that same day over the wet floors. We did not install floors for several weeks after and I notice water coming through the gray leveling stuff they put on the floor. Our floor company put down an orange sealer (Schluter sealer) they had used in our shower install over the wet spots the day of installation. I'm sorry I do not know the names of all the products used. Over the months we continued to watch the white powder spread until this week, June 19, when we ripped all the tile out and found a small lake under the tile, water was everywhere and had already started molding the brand new cabinets. I also cut holes in the base of the cabinets and jack hammered the existing (wet) thin set leveling material and I sealed the concrete and cleaned up the mold on cabinets and painted them with primer and high gloss trim paint. I'm sick over this...We now have concerts floors again, and no evidence of water anymore, we are running a dehumidifier and the AC is low. But no signs of water coming through. I have been told so many things, from so many different experts, and we spent thousands of dollars on the floor and to put in a new floor and have the same issue is not an option. I need help! I did have one guy who works for a floor manufacturing company tell me that its water vapor and the vapor can't escape so it turns back in to a liquid. He also talked about using an epoxy material to prep the floor. No floor company seems to understand what's happening, and the rest of the house is ok. UGH Help please. Also at this point we don't really care what we put down as long as it is not carpet, another floor company told us to use a water proof vinyl flooring man made manufactured material. At this point I'm desperate to get this floor down and get back to living.
