To clarify i want to put a stud wall along the edge of the perimeter drain.
Stud out a concrete wall with french drain.
My basement has a french drain around the perimeter.
I would not put my bottom plate on top of the gravel of the french drain.
Preferably with metal studs and dry walls.
Maybe 5 or 6 feet of wall space where you would see water seeping into the drain at times.
The lip is 2 25 inches high and 6 5 inches deep.
I have french drains around the perimeter of the basement with a little curb like lip in front of the walls.
The water seeps into the french drain in one corner only.
Basement is about 50x30 ft.
You can bump the framing out in front of the drain but you will lose a lot of space that way.
As for the inside if water get s in and runs down the wall you must have a gap between the framing and the wall to let it run into the drain tile.
It is not an external french drain its a french drain along the walls that drain into a sump pump.
We plugged the original dime sized hole but obviously the water still seeps through in that general area it would be fine to leave that area unfinished.
Now here are my questions.
Do i put 2 inch rigid foam on the cinder block wall it would be over the drain and then add the stud wall to meet.
