If the wall in my basement is leaking very slightly, is the main/only solution to the actual water issue to add grading outside? What else?
It is under a deck, which I can rip up a bit and fill with dirt, but is that likely to solve it?
We noticed from slightly bubbling paint and efflorescence.
If you want solutions that don’t involve digging up the outside, sealing the wall, and adding proper drainage to direct the water away, you’ll probably need to say more about how the wall is constructed and what sort of drainage currently exists.
Do you have a sump pump? What is the wall constructed of (concrete, cinder block, stone, brick, etc)? Is the basement finished?
