WHAT ARE THE BUILDING REGS REGARDING CHANGING FLOOR BOARDS TO A CONCRETE FLOOR?
It also depends on what’s underneath, and what type of sub-floor decking you have, and how strong the joists are. One point few people consider is that fresh concrete has a whole lot of water in it, and if you have an open space underneath the area where you want to pour the floor, a lot of that water will end up down there. If the area is finished (like another room) everything in it will be soaked.
