Hi. Would be gratefull of any help with the following points.
1. I am putting in a concrete floor in a barn. I am going to dig the original mud/stone floor out, but am unsure how far to dig down????. And in what order do i put down the insulation, concrete/sand etc.
2. The area that needs doing is approx 123 feet by 26 feet. As it is quite a large area, do i need to do it in stages.
3. Is it essential to use the steel grid to prevent cracking.
4. Do i need to leave a gap around the edges for expansion. And if so, what goes into the gap when it is dry.
5. I understand the concept of ensuring the damp proof membrane comes up the side and is supposed to meet the d.p.m in the bricks. However it is impossible to do this, due to it being very thick stone, and there is obviously no d.p.m in place. So how do i get around this problem.
6. Last one i promise. ha ha. I have read that is best to put any waste pipes in place before laying the concrete. Is it best to do this, and if so, do i just need the one pipe laying and just link all the other waste water in the barn to this one pipe. Also when the pipe comes through the concrete floor, how do u ensure it is damp proofed.
I know i am asking a lot, but would appreciate any help..........Thanks
