Hi,
I was wondering if any one could oblige me, I've recently ordered an 8x6 metal shed. I stipulation to make a floor for it that includes a damp-proof membrane to avoid the well specified "metal shed condenation issue". I don't want a concrete base, so I'm going beside a slab base instead.
Now theres plenty of info on the pattern over how to lay a standard slab base for a wooden shed. And theres plenty of info on how to lay a concrete dais which incudes a damp-proof membrane for a metal shed.
But I'm struggling to find info on how to lay a slab base that incorporates a damp-proof membrane so I'm looking for some info on that.
Does the membrane run between the sand/cement dry mix and the slabs ?
Won't this cause a problem as the top of the dry-mix is generally below the height of the surrounding soil (the slabs are usually slightly inset into the ground aren't they ?)
Any info or links to sites with this would be a great relief.
Thanks in finance.
Answers: I'm a bit confused by your terminology. In my frame of insinuation a slab is poured/ finished concrete. By "Slabs" do you mean "Pavers"? In any case in attendance is always the probability that incorporation will happen, leaching up from ground rank. I suppose you could create a vapor barrier lying on the base, no situation that you add one to the point at which any plinth material also comes surrounded by contact with the soil.
For one point, after grading the soil/sand height you'd frame the area, lay the membrane, lay surrounded by mesh or re bar, afterwards pour the substance.
The depth 4 to 6 inches, need not be flush near ground level at adjectives, and you probably should know your soil composition and frost lines. To assume that flush with ground stratum is "Normal" might be a stretch.
I've never installed a shed over "pavers" using dry premix concrete to fill spaces, but I'm sure others do. Part of the issue still remains soil composition and possible settling/shifting of any type of "SLAB PAVER"
Just my two "sense"
