Water management for a stepped foundation daylight basement
I am currently helping my builders excavate for a stepped foundation for my future house with a daylight basement. I'm not sure what to do for a footing drain with the stepped foundation or even if it is necessary. The obvious answer would be to get a pro to handle it, but I am in Japan and footing drains, exterior damp proofing, etc. are unknown to the pros that I have met with here.
From what I gathered from conversations with my contractor, there aren't liquid water problems with foundations in the area. There aren't many basements in the area either—just crawlspaces. A neighbor that does have a basement (with no damp proofing, footing drains, etc.) told me that although he doesn't have a problem with liquid water, the humidity in the basement is high, so his basement dehumidifier fills up quickly. I don't want that for my house so I imported some elastomeric waterproofing paint to coat the top of the footing and the outside of the basement wall.
From reading articles on GBA, it seems that all new foundations should include a footing drain, but is installing a footing drain worth it in my situation? (No one experienced with them, having to design, make, and install it myself with a drill and PVC pipe, a lack of known liquid water issues in the area, and several steps in the foundation to deal with.)
