Hi Jay, dont worry ......I am not going near a concrete floor....what I am trying to do is make a floor that will be solid and support our underfloor heating plus a flagstone or terracotta tile on top. What I dont want is concrete......for all the reasons you have mentioned. BUT I have to know my onions before I convince my husband and his adviser.....so, limecrete, is what I want to do. If I am honest I would have liked a polished earth floor....but my husband passed out at the suggestion! That will take some work I think. In the meantime, I need to have a solution that works for us and is cost effective....hence trying to use a limestone gravel.... Just waiting for the email responses from a couple of limecrete companies and then hopefully all will be well!
Thanks again and pop in if you are passing!
