Suggestions Needed
I've posted in the past about my recently purchased home built in 1935 with a partially recently finished basement. Adding to bedrooms and full bathroom facing street side with 2 egress windows. It was renovated by a local well known company but maybe that should've been a red flag but regardless after inspections and structural engineer report we bought. After snow melt and recent rain we had intrusion and upon further investigation I pulled off peeling paint in unfinished wall and found spalling concrete/ parge coating where water had come through. The entire unfinished wall shown is where water entered especially between where there is a cmu wall dividing the utility room and under the staircase where it literally drips water after heavier rain around abandoned gas pipe. Now I've had a few foundation contractors come and give their opinions and solutions. Most suggested interior drainage with vapor barrier covering wall to drain into sump. I wanted to have the exterior re excavated but due to proximity of neighbor many have said it is not feasible. One of the last photos shows how the seller did it and had someone apply sealant that is obviously failing. So from here im not exactly sure what to do. We did re do downspouts to drain separately from discharge pipe from existing sump that was not draining properly due to poor installation. Unclogged gutter as well but due to the gravel and patio area having tricky grading we still get some water intrusion during heavy rain. Any advice on what my plan of attack should be just don't want to move forward with a expensive solution that could come back to bite me again later in the foreseeable future. Thanks for reading if you made it this far.
