We're looking to do some water/damproofing to our cellar walls before putting up the dry lining. There's no rivers of water getting in but the walls are damp. At the moment all we can come up with is to paint some WPM membrane on the inside (too costly and hassle to do the outside) with metal struts to attach blueboard too. We're also putting in a few vents on the walls and the floor (where it can at least circulate).
I've been looking for someone who does tanking but it's not too easy to find anyone, especially in Adelaide. Does anyone have any more ideas of what we could do or know of anyone who does tanking, and roughly how much would that cost for a 3x3x3m room.
Cheers.
