I have a question, hopefully not too silly.
In the basement, right under the window, water leaked in where the floor meets the wall.
The side of the house has a couple feet to the neighbors driveway which is higher.
I immediately assumed there might be cracks around the window.
I double checked the entire side outside, filled small cracks around the window, (dug about 2' down & the wall was solid/no holes) raised up our side and created a ditch along neighbors driveway.
Inside we drilled a hole in the brick under window and filled it with that spray can foam stuff.
The ditch works good, I watch the water flow down to the gulley and there was still moisture but not actual water flow coming in.
Digging all the way to footer outside is not an option right now and at the beginning of winter we had a nasty storm, tons of rain and snow that melted quickly.
Inside now about 8 bricks down towards the sump pump we got actual wate flow coming in the bricks at the floor like below. So we drilled a hole again & the water rushed out.
My problem is we have a normal brick basement but on the outside there is another concrete exterior hollow wall coming off about 1.5" from the house. On the outside of the house , right under basement windows and all along entire house you can the the ledge from this extra exterior wall.
I have found holes in this extra wall in past & have filled it with spray foam and sand, the hole was never ending, anything I put in it dissapeared so I'm assuming this wall is hollow.
I'm scared because this extra wall itself can hold water against the house, I know I can seal it from the outside as you mentioned, but I'm wondering if I can literally fill this entire wall....entirely and if so what would be best to fill with.
I also want to know if it is ok to actually drill holes on inside and fill the bricks with something as well.
Such as filling the top 2 rows of bricks with spray foam or since the walls hold water, can I literally dumps bags of concrete mix either in the bricks or in the extra hollow wall, I'm thinking the powdered concrete will work its way around, hopefully fill whatever hole I have, then eventually when it rains, water will get in as normal, mix with concrete and harden?
I can't find any info at all about this extra exterior wall. I pulled the house plans and saw the house was suppose to be bricks, it is sided and has never been bricked.
Through research I am thinking that this extra wall on exterior is what the brick would have sat on, but I can't find out if that extra wall runs the entire distance down, but I am thinking it does because we dug once about 6' down and it was still there.
So I am sure sealing the wall would help but technically I will not be sealing the actual brick on outside, I'd be sealing this exterior wall which is 100% hollow and will probably hold whatever water it can get and then since I can't find any info on it.....
I am very curious how this extra wall fits in with the drain tile down their, I'm wondering if the extra wall is sealed at bottom and doesn't even have access to the drain tiles so it just holds the water.
If you have any info on this please forward to me, also that exterior wall is fairly thin, but The only places I have found holes is around the windows and along our driveway, otherwise no cracking or anything, I can send photo if needed, thanks a whole lot
Now, last summer the neighbor got there driveway redone, it is pitched even more towards my house
