Help!--Can I pour gypcrete floor over gypcrete floor?
Hi, we are finishing our basement and putting marmoleum and wool carpet over the floor. The original floor had a significant slope toward an old floor drain, so our contractor suggested hiring a floor leveling company to pour gypcrete over the cement and level the floor. I googled gypcrete and found that a lot of people have had lot of problems with gypcrete over the years, so I was hesitant. My contractor said that gypcrete has improved within the last few years and that the only thing with gypcrete is that it can't get wet. I trust my contractor, so we gave him the go ahead.
Well, I don't know what the floor workers were smoking that day, but all they did was pour a new gypcrete floor; it still sloped dramatically, it wasn't level at all. I complained to the contractor who contacted the floor company, who promised to redo it. I asked the owner of the company if pouring gypcrete over gypcrete was a problem. "Not at all," he assured me. What do I know? So, again we gave him the go ahead.
I asked the contractor to meet the floor workers on the day of the new pour and be very explicit re what was to happen. In the morning, he texted me that he talked to the workers and everything was proceeding nicely. Well, when I came home from work that evening, I went downstairs to check the floor. All the workers did was pour a couple of patches of gypcrete over a couple of areas of the floor. This was not the smooth level floor we were promised. Even worse was that one of the new patches had dried and was cracked and coming off in large pieces. So, once again I complained to the contractor who called the owner of the company; he is out of town and will be back on Monday. I'm sure that he will promise to clean off the cracked gypcrete and redo everything to make it right.
My question is, what are the long-term consequences of pouring gypcrete over gypcrete? What other options do we have? I imagine the best option would be to have the whole thing ripped out and have a brand new cement floor poured; but that would be thousands, especially now that the gypcrete would have to be ripped out, as well. I want as much information as possible so I can be prepared to talk with the floor company owner. Any info or suggestions you have would be much appreciated.
Thanks in advance for your help.
