Foundation capillary break & waterproofing
My wife and I are building a small home (First Day Cottage) on a full foundation with a walkout on the downhill end. I read about having a capillary break between the footing and foundation wall and it makes sense to me. When I asked the concrete contractor about it he said he’s never done it (though he did remember one other customer who asked about it a couple years back). I get the impression they won’t leave me much time to do it myself between pours. I was thinking I’d use Drylok Clear but their tech support said I would need to let the concrete cure for 28 days before applying to the footing. So that’s out. Is there anything I can use on uncured concrete that is relatively easy to use? If not is there a workaround – a way to mitigate after the fact?
The other aspect of the foundation I’m struggling with is what to use for waterproofing, again planning to do myself. My original thought was the black stuff but turns out that’s damp proofing and sounds like waterproofing is a better idea. Looking online there are as many opinions as products. I’d like to use latex Drylok or Drylok Extreme but worry about how well it will hold up over time. I’ll be installing 2″ XPS foam board over the waterproofing whatever it turns out to be. Any advice about waterproofing options is much appreciated.
