I am building a LEED home and want to know what to use for a capillary break between the footing and foundation wall.

    Jack,
    Here are some options:
    1. Dampproofing
    2. Low-permeability paint -- for example, UGL DryLock latex masonry paint
    3. Elastomeric paint
    4. Delta Footing Barrier.

    Some builders have used 6-mil poly, although poly isn't easy to work with in this location. (Then again, asphaltic dampproofing isn't easy to work with either.)

    Here is a link to a relevant video: Installing a capillary break on top of concrete footings.
