Crack in Poured Foundation Wall

Soemtimes when itr rains heavy and for an extended period of time I get some water in my basement in one spot.

First thing I did was seal the joint between the floor and wall with hydralic cement and then painted it with Drylok.

Unfortunately, there is a small crack in the foundation wall that runs vertically from the window (there is a window in the foundation just above the crack) to about 10" from the floor. Now, water comes out of this crack about 24" off the floor.

It would seem the water is working its way upd the inside of the wall and then coming out the crack.

I am planning to use of the urethane foam low pressure injection products to fill the crack.

Any thoughts on this approach?

I am thinking of using the first product on the page at thsi link:

Any thoughts?

The cause of the wall leak is water pressure building up against the wall and taking the path of least resistance. All your sugestions may work for a short while but will eventually fail.

I realize this is not always practiical but the best way to approach a wall leak is to go after the cause so the water has to be eliminated. This can be extensive and will involve excavating next to the wall placing tile and wash gravel next to the footing. The water than has to be trenched to daylight or to a sump so it can gather and be pumped away. before the backfill the wall should be pressure washed and parged with a cement mortar, covered with 6 mil or tar and then backfilled with granular clean fill so the easiest path of least resistance for the is down to the perforated tile and out of your life.

The best of luck to you.
