I am working on a Victorian stone built barn. The first problem is that the floor has a 6" slope up from its door to the back wall. The floor was broken flags and earth and when the weather was bad it was very damp.
I am removing 4" of the old floor from the door end and when I get to the back wall, I find that when I dig down 10", I am below the wall stones, because the barn was cut into a slope and they saved time by contouring the "foundations" into the slope. So I am having to underpin about 30' of the wall. This is very slow but seems to work.
My concern is because I am short of labour, I was going for a self levelling concrete mix with a thickness of 4" but would like it fibre reinforced because it will be laid on earth and being water proof would be an advantage. The other alternative would be to use no fibres but use a mesh reinforcement, but I am worried about the dampness of it all.
Once the concrete is finished the wall will be tanked to a height of 2', overlapping on to the floor.
Any thoughts on my methods?
