Hi all,
Laying a concrete base for a concrete sectional garage which I bought. Our garden is very damp, not investigated the cause yet but we're in a clay area so it seems like water is retained in the top soil for a while after it rains. There is a concrete slab in a different location in the garden which seems to suck water up through it after heavy rainfall.
Debating whether or not to lay a DPM in the slab because I don't know if it will be of any use - where do I dress the DPM to?
Do I have the DPM coming out of the side of the slab, then dress it up the side, under the sectional panels and then fix it to the internal wall of the garage?
Or do I have the DPM coming straight out the top of the slab, if I do that won't it create a hollow square of non-attached concrete all around the perimeter of the slab?
I'm just concerned I won't know where to finish the DPM to create a watertight floor, and if there's any concrete exposed to water, will the DPM just trap the water in the base?
Any thoughts or advice greatly appreciated!
