I thought this was going to be fairly straightforward. I expected to be able to walk into the local building supply stores, buy some kind of sheet drainage membrane (what's the correct generic name for that dimpled plastic stuff?), attach it to the wall with glue or nails then move on. Well in spite of the fact it rains here practically every day for three months during the winter, it seems everyone still just rolls on a bit of tar and hopes for the best. All but one supplier had no idea what I was talking about - on a related note, they all sold lots of products that deal with wet basements.
The one supplier that came through had something called "Delta-MS" (http://www.deltams.com) which they considered a commercial product. Unfortunately they didn't really know anything about it and didn't appear to sell all the components necessary to install it. After an on-line search I found a few similar products available elsewhere including "Platon" (http://www.armtec.com/foundation). The Platon and Delta-MS both have the dimples against the foundation creating an air gap for the water to travel down and require no surface prep other than caulking a top bead and a blob where the form ties exited. Other systems like the"American Wick Drain" (http://www.americanwickdrain.com) mentioned in a different thread here have the dimples facing out with a geotec fabric between the sheet and the soil. As well it requires a liquid waterproofing be applied prior to the drain sheet. That sounds like considerbly more expense and labour. What am I gaining with that? Does anytone have any experience with something like Delta-MS (which seems to be all I have access to here in Victoria)?
Thanks.
