The PWF Solution

Last day I spoke briefly about lateral pressure failures in basement walls. There is a nice solution, and that is a PWF wall inside, if the subfloor is suitable or can be made suitable. A notch is cut into the basement slab, and the wall installed without sheathing. Nice clean solution if the wall is straightened and waterproofing is applied on the outside. This wall must be structurally designed. Excessive lengths of openings can also be an issue, where doors, windows, the like occur together. It must be attached to the floor diaphragm and the floor cut must be grouted. Also an abutting wall maybe required, for lateral support.
