Hi All, Before I owned our house, french drains were installed in the basement There is a gap where the floor slab meets the wall and it looks as if they dug out some of the floor slab, installed the drains, then cemented over it.
The drains are clogged. Any way to unclog without busting up the concrete? I'm not sure how the drains are constructed and can't find much information on them. Any info is appreciated...thanks!
