Evening folks,
I'm tearing down an old outbuilding as its just too small, lets in water, cold, dark, etc... and replacing with a new timber framed/clad workshop, sat on a 4" blockwork "ring", on a conc slab foundation. I'm comfortable with the timber work and poured a few slabs in my time, but i'm unsure on this part...
Site is sloping, so looking to dig one end into the slope to a depth of about 750mm. See sketch:
I was thinking i'd bring the visqueen from under the slab up the end/sides of the blockwork to above ground level, install a 4" permeable pipe along side the slab and back fill to ground level with a permeable fill material (gravel..). Is this going to be enough to keep the blockwork/inside of the building dry? I've seen a bituminous paint on the back of blocks used before - should i be doing this too? Any particular brands or specifications to be aware of?
Any other water proofing ideas you could suggest for me?
Advice gratefully received.
Mick
