Does anybody have any information on prefabricated basement walls? I am thinking of useing a PA company. Superior Walls. They make the basement walls in a factory with foam insulation already in and studs. They set up your walls in 8 hours, and then the floor can be poured. I saw it on This Old House or something. I also wonder if a concrete floor can be "finished" at the same time it is poured, to look like tiles or marble. Or does this "finish" have to be done in a second step. This will be a walk-out basement. Also, need good info on up-flush toilets!! Thanks!!
