Leaking where basement wall & floor meet

When there is a heavy rain or massive thawing, my basement floods with water entering where the wall and floor meet. The gutters seem to be fine. (I ran water through the downspouts which tie in to drain tile originally installed outside around the foundation, and water exited at the ends of the pipes.) Would hydraulic cement or epoxy around the inside perimeter (maybe after chiseling out a "V") solve the problem? There's no sump pump.

Howdy, the space is for expansion of the basement floor slab so do not fill it with cement. You could try self leveling cement joint compound -caulk for cement, It is a issue of ground water entering into the basement resolved by installing a french drain inside the basement next to the foundation and installing a sump pump. But first what is the grade around the house( slope away of tword the house)? Is it on all sides of the basement slab or one area?

The grade slopes away in front of the house and somewhat toward the house in the back (approx. 3' higher 50' back from the house. The flooding problem occurs in both the front and back. Changing the slope in back so it's away from the house would entail removing 15-20 large trees. I've considered building up the slope at the back of the house to grade it away, but would encounter other problems such as a doorway, deck, driveway, and more trees. I've wondered why the drain tile around the outside of the foundation (front & back) doesn't handle the water before it gets inside. To complicate the matter, this is a multi-level house. The drain tile is around the perimeter of the "living level" of the house which consists of the kitchen, dining room, and livingroom. On one side, there is an attached garage (down 4 steps from the kitchen), and the drain tile is 5' or so below where the garage floor meets the living section. On the other side, there is a level going up 6 steps from the living level and the tile is buried there, too. I hope this isn't too confusing.

Re: Leaking where basement wall & floor meet

Your drain tile must be clogged, collapsed or just improperly installed.

The water collected by the drain tile should be going somewhere, but since there is no sump pump, where is it going? Can you see a discharge line? Do you know where it leads? Do you see that water coming out somewhere or is the line tied to the city system?

I know these seem like odd questions, but you'd be surprised if you knew now often builders install these tiles without a discharge line as if they expected the collected water to mysteriously vanish.

As the other member in this forum suggested, your best (and more affordable) option at this point, since you have an attached garage, deck and all these features, would be to correct the drainage problem from the inside, by installing an interior drainage system and a good sump pump system.

There is drainage at both exits of the drain tile. One exit is 30-40' away from the garage side of the house. The other is in front of the house and goes downhill underground for nearly 200'. The gutter downspouts tie in to them, so it's possible that the water that exits the drain tile may be just from the gutters.

Howdy again. without photos . You may consider installing a french drain in a gravel bed in the yard. If the slope is upgrade from the house. Was just reading a book about this- suggested trenching, 10 foot away from the foundation, to the bottom of the foundation installing 8" of gravel then the drain pipe then a foot of gravel and back filling. The out let must be down slope at 1/4" per foot of run the outlet down slope from the house or into a sump pit... Good time to get some bids from a waterproofing company and pick their brains about the alternatives.

Re: Leaking where basement wall & floor meet

Thank you for your input. The slope is upgrade behind the house, but downgrade in front, where flooding also occurs. The front was fine for many years, but now is a problem, too. The idea you mentioned is pretty much the way the current tile is, although it's right next to the foundation, not 10' away. That there's something physically wrong with it seems like the most logical reason for the flooding problem. I don't think the procedure you mentioned could be done because of the trees and decks (front & back). Reluctant as I am to tear up the basement floor, I may have to have an interior drainage system installed by the footing on the inside, including a sump pump. Now, the hardest part...finding a good contractor.

Thank you. Very interesting. I've contacted them for more info.

Re: Leaking where basement wall & floor meet

A sales rep from XYPEX took a look at my flooding problem a few minutes ago. I'm psyched! He recommended a couple of contractors who do an excellent job and suggested calling them when there's a flood so they can do a more thorough evaluation. He'll send me info. on some projects where the work was done so I can speak with the customers themselves. Although sometimes it's a DIY project, he said mine is not one. He also said the interior drainage system with a sump pump wouldn't work for me--that is only for water coming up through the floor. Thank you so much for the suggestion, Hank! I'll continue with this approach and report back at a later time.

call the main office now his advice should not be followed.
You should correct the problem before it floods not after?
If you had a fire hazard you would not wait until after the fire to fix the problem.
