Crawlspace
My crawl space has some standing water. It is graded fairly well to a low point but the left side takeson most of the run off and leaves my foundation wet with the low point is on the opposite side. The driveway is sloped to where I think water comes in under my garage and into my crawlspace as well. I want to install an interior French drain along the footing. I have seen people say that you don't want to dig to close to the bottom of the footing but if I lay a 4" perforated pipe there it would need to be 8" deep or so. Does anyone know the real answer. Will I disturb the footing by digging beside it. Any advice on if it’s better to add drainage to inside or outside. I’ve seen inside has less chance to clog and outside is more expensive. Any advice helps thanks.
