Bad idea?? Hello everyone. Building an extention on my house with a full basement. Water table is 10.3 ' so exterior French channel and water proofing walls is absolutely a must. I got the walls ready to go and I have 4in green pipe coming with 2 rows of holes on the bottom. This is the dilemma..... if I have basin outside I need it to be at least 12' long to go deep enough because the pipe is 8' deep. Where do you buy such a thing? OR run a 4in pipe under my footing into an interior basin. Much easier and cheaper but would you go this route??
