One corner of my basement (about 16 LF) has approx 4' high poured concrete walls and framed knee walls above that. Problem is the sill is below grade and has become very soft. Even though I have diverted outside drainage, still when it rains (or snow melts) water comes (an brings the sandy dirt with it) into the basement from between that concrete foundation wall and the soft sill.
I am confident I need to jack this section up and replace all or portions of the knee wall, questions are:
1) Can I replace this with new treated wood amd if so, how do I seal the joint (between concrete and treated wood)
2) Can I do this from the inside...without trenching the outside of the house
3) Should I consider capping with concrete block and is there any reference material to help me with this
I know this is a big project and needs to be done; however, I am comfortable with jacking a house just don't know how to attack it from there and can not afford to pay the $6,000 estimate.
Thank you for your input. ...brhuck
