We recently put an addition on with a full basement and for the first time in all of our thirty years living here we got water. This has happened to us three times within the past three years.
when we put the additon on, we put in an insulated floor -styrofoam insulation between slats with 3/4" plywood on top then put 12" vinyl tile squares on top of the plywood. Needless to say the three occurances with water badly damaged the floor, rotting the plywood in some areas. We had the B-Dry System Co. install a french drain around the entire inner perimeter of the basement. The container for catching the water has both 1/3 and 1/2 horse power sump pumps. We would like to install a new flooring. The basement is a pottery studio and the flooring needs to be washed down on a regular basis to keep the clay dust under control. Should we do the same type of flooring that we had originally done? Should we do just a vinyl tile over the concrete? Is there something that can be "poured" over the concrete to create a finished look? Is there some type of large mat that can be rolled down. As you can see we are open to suggestions that will work. Remember We need a hard surface for the equipment. Also, was the typeof insulation we laid down the proper type or should we have had an air space between the concrete and the plyboard? Yes, I'm quite sure we had a vapor plactic barrier between the concrete and the insulation.
