Greetings. First time caller over here to the plumbing section. Here's the deal. I have a customer that wants us to fix the leak into the basement. I tried like hell to get him to get someone else but he insist we do it. Anyhow, we have a 4" old rigid conduit 3ft underground passing through foundation (5"hole) into the electrical CT cabinet. Currently, the water is getting down into the trench and following the conduit on the outside, dripping into the CT and out a weephole. He was supposed to fix this 6 months ago. I don't know much about plumbing or water leakage but I'm thinking excavate, fix gap around conduit with hydraulic cement, put some gravel french drain in just b4 it enters foundation slanted downhill to divert the water, cover up. Does this sound like a good plan or bad???
