I had a question about the gap at the wall with the french drain. We are concerned about radon, and if we do not anticipate any water entering the basement again after install of the drain, can we not have this gap at the wall?
Can this simply be cemented over? Contractor said it could.
Also, a local contractor stated he would not need to dig any laterals as the water under slab would find it’s way to the perimeter stone/pipe. Stated, water comes in from under the foundation, and then to the stone trench. Even though my basement is small, 80 linear feet, and there is no stone under my slab, he stated the drain would handle it. This company is local and been around for 70 years, hundreds of references.. no money up front, guaranteed.
Said they dont need to pitch the pipe either. Said it simply works.
