I have a corner room in my basement that is literally lower in elevation, as you walk through the door you step down about 4 inches. The two walls of this room seep (and sometimes to the point of a trickle) water during heavy, continuous (2+ days) rain, about 2-3 times a year. I'm considering installing a sump pump in this room. However, since a sump pump is installed in the floor, I'm thinking it probably wouldn't have any effect on water coming in through the walls?
My house was built in 1896 so there's no drain tile around the footer, the walls are stone, filled and covered with concrete. And I live on a hill, one neighbor higher than me and another lower in elevation. One of the walls that leaks is on the side of the house with the higher neighbor. I have a good gutter system on that side of the house already, but the ground on that side has a dip from years of water falling off the house when it had no gutter, so I have yet to re-slope it away from the house. However I'm not convinced that will fix the problem, because the other wall that leaks is under a concrete porch, and it still leaks.
I think a sump pump will help relieve some hydro static pressure, but will it have an effect on the leaky walls?
