The work generally sucks but it's definitely possible to DIY. The difficulty mainly scales with access; if you've got a lot of room, it's easier to excavate (especially if you haven't used similar equipment before), store the dirt, avoid digging by hand, etc. Destroying/rebuilding decks, stairs, concrete and asphalt or digging is also a pain, though you didn't mention any obstacles. Your steps look good: locate any utilities - call in and mark anything not covered yourself excavate - rent or borrow a mini excavator clean off the wall - use a pressure washer and a wire brush patch any cracks - use hydraulic cement apply water proofing compound - fluid applied (spray or roller) and membrane (peel-and-stick) products works best, check the instructions for minimum thickness/layer count, dry times, etc and pay extra attention to cold joints which are generally the most likely to leak create a free-draining plane - once it's dry, cover the waterproofing with a dimple membrane, rigid insulation or both install weeping tile - use perforated PVC (avoid the flexible, black pipe), place it beside the footer (not on top) with the holes facing down, ensure that the top of the pipe is even with or below the top of the footer, create a burrito out of nonwoven geotextile fabric, 3/4" washed + crushed stone with the pipe in the middle (less stone below the pipe more stone above and to the side) install cleanouts - use a combo fitting or build your own using a wye + street/spigot 45 and bring pipes up to grade (placement depends on how long and complex the foundation walls are), capped with a scew-in cleanout, where necessary for future inspection and maintenance fill - backfill with more 3/4" stone until you are a foot or so from grade, then cap it with clay, sloping away from the house If you're no doing the whole foundation at once, I'd suggest doing one wall and continuing around the corner for a bit so that you can deal with the transition. It's enticing, both financially and mentally, to cut corners but you don't want to do the job twice. Do a good job cleaning off the wall and footer, follow the waterproofing compound's instructions and don't go with cheaper damp proofing materials, avoid flexible pipe wrapped in a sock and buy the proper pipe, fabric and stone, don't skip out on the drainage layer or backfill, put in a couple of cleanouts and insulate (exterior insulation is continuous and superior).

First things first, you need to get a moisture test done to see whether or not there's actually a negative hydrostatic pressure (aka "rising damp") issue. If there is, you can explore options, but I'd recommend a proper epoxy based vapour barrier like Ardex's WPM300 if you're needing to seal the floor, but the absolute best option possible would be to fix the issues at the exterior before the moisture even gets in. Tl;dr eventual damage from higher moisture level sitting in the foundation causing erosion prematurely. Look at guttering/spouting, re-grading, exterior drainage, make sure it's all doing what it's meant to. Standard tiling waterproofing in this situation? Yeah nah, it's not designed for that mate, and it's utterly useless at the job you'd be trying to get it to do - it'll peel off the concrete because of the pressure building underneath it, it doesn't grab as well as proper vapour barrier membranes. That applies to both roll on membranes and sheet membranes. It's designed to keep water within where it's been painted on, and channel it down to a drain. Not to stop rising damp. As far as the whole crack isolation thing, if you've got shifting foundations then crack isolation membranes can only do so much to alleviate before failure sets in anyway. It's a band aid, not a proper fix. More on reddit.com

Tile coach has some pretty great videos where he tests the waterproofness of foam board vs membrane and membrane wins (albeit, marginally). The membrane waterproofing is thicker than the felt that comes preinstalled on the kerdi board. With all the requisite seam/corner/screw taping, I feel great peace of mind using membrane over concrete board, and it’s cheaper. However, for the ease of installation and ability to wet shim, kerdi board is a great option, it’s just very $$. For professionals who are trying to move quickly and save time, I think foam board is a great option. However for a DIY bathroom, you’re going to be going slow anyways, so why not save your money and get the best shot at waterproofing correctly (I emphasize correctly because there is a lot of room for error while installing your own membrane, so do your research). Remember, get the air bubbles out with a drywall knife, but don’t push all the thinset out, have the right trowel size, and overlap seams by 2”! More on reddit.com
