    Question Burying a grade-level wall

    Our house has a stepped block foundation with a 3 ft crawl space. By "stepped" I mean the ground level in the front yard is 2-3 feet higher than ground level at one corner of the side/back yard... the block steps down about 2-3 feet from the front along the side and the opposite back corner making this side/back corner the lowest ares of the yard.
    Since this corner is the lowest part of the yard it's a problem spot for water collection, especially in Februaruy when the ground is frozen solid and we get 8 inches of snow followed by 3 inches of rain. It also happens to be the north-facing wall, which makes it shady and prone to mold. Currently, the siding is rotten along the bottom in several spots and needs replacing.

    I've done a considerable amount of drainage work, but every mid-winter rain and spring melt-down we get water in the basement. So, I would like to raise the ground level around this side and back corner to shed water away from the house and into the existing perimeter drainage system.

    I think the right thing to do is to cut away part of the wood framing, extend the block wall up, seal the new block wall, and then raise the ground level around this corner. I'm not afraid of hard work, but that's a ton of work!

    I'm looking for any suggestions on how I could leave the existing framing in place and somehow seal the walls and bury them without creating a future problem? Rigid foam board, cement board, or PT plywood covered with ice & water shield then covered with something like conpro-seal? Yeah, I'm probably stretching it here, but I know how much work (or money) will be involved in cutting out the framing and adding the block.

    Thanks for any suggestions
