Another Seepage Question
I just moved into this house. What I thought was an issue with the previous water softener system may in fact be a seepage issue along the floor/wall seam. This is based on the water up the wall, which doesn't seem plausible as leakage from the new system (which has been in 2 weeks and showed no sign of water until heavy rains this weekend)/
Attached is a picture of what I am seeing. The complication to this issue is that this is the wall that is shared with my garage, meaning it isn't a grading issue outside. This is the uphill side of my property, with the downhill side being a walkout. There is no water flowing into/across the back of the garage.
About 10' to the right of this is the sump pump.
Would my only recourse to be have an edge drain installed along the inside edge of the wall here? It doesn't seem plausible or practical to excavate the back of the garage to repair from the outside.
