Building house at the moment. We decided to go with the precast concrete floors upstairs to eliminate sound. They went in just before xmas. The plumber then did his few bits for upstairs, we put downsteel mesh and then poured 3+ inches of readymix on top of this. The problem is that we want to have block walls upstairs, and not timber partitions, also for sound. The blocklayer is saying that we need to use lightweight blocks, but the crowd who put in the concrete floors said that we could work away with normal blocks.
Anyone throw some bit of light on this???
