Waterproofing stem walls with above-grade slab?

[Shoester]

I've finally got my foundation poured for the shop, and I'm wondering if I need to be considering waterproofing the walls before backfilling. The slab will sit 6" below top of wall, but will be above the surrounding grade. Because the slab will be above grade, is there any reason to waterproof the walls? Also, any benefit to putting in some train tile around the footing, routed to the back of the shop on both sides and out to daylight? Or is that a waste of time with everything being above grade? Thanks for the help!

If you need permits best to ask them before backfilling. My house has the same design. I sealed the walls with the black tar like stuff and the city made me put perimeter drains in. Although I didn't think it was necessary, neither did my geotechnical enginer. BUT i do live in a really rainy area and in hindsight I am glad it's down their keeps the watertable away from my slab that has hardwood glued on.

FWIW, I'm on the other side of the state near STL, and built my shop in similar fashion (slab is above grade, full perimeter foundation with footers below frostline, 6" stem wall). I did not waterproof the foundation walls, nor install drain tile. No issues whatsoever five years down the road.

Remember that code is a “minimum” spec. Not aware of the frontline in Missouri. Water that freezes (penetrate then expand) can do damage. If it was my project I would build to the upper limit of my budget. It gets said a lot around here but tends to hold true. Buy once, cry once.
