what u mean with grading on the outside and the water source is just when it rains and after winter when snow is melting.
Grading meaning how the dirt/ground slopes away from the house.

Water source meaning an open area for rain, or located near a gutter downspout.

Fixing leaks is usually a two prong approach.
1) Improve drainage on the outside, and
2) Patch cracks on the inside.

In fact, if you improve the drainage, that may get rid of leaks even with cracks left alone.

while the previous is always possible, you've got a better chance of seeing God show up to stop the water than remediating it thru only re-grading in my waterproofing experience,,, it MAY stop for a bit but the underground channels & rivulet passageways'll still be there still directing wtr into your very fine bsmt,,, don't forget wtr has all the time in the world while you are on a different timeline !


i've never seen improvements in grading resolve leaky basements,,, not arguing w/those who have - i just never saw it work permanently.

That's why I said fixing leaks is usually a two prong approach.

i can't disagree w/the aforementioned ' two prong approach ',,, however, its my belief exterior work's largely window-dressing,,, obviously less water reaching basement walls & footers is to any structure's advantage,,, bang-for-the-buck, regrading's h/o-diy work imn-s-hfo

vertical crack on pour foundation, water leaking


hey guys ok i started digging the hole, and i find it a bit diffucult because i run into this stuff don't know if it's clay, it is really sticky and got this like light green kind of colour, more like the cement power mixture. i got as deep as 3 feet i can see the crack getting thinner. i guess it is better if i dig all the way down to the foundation footer right? or would it be enough if i start patching it now.

ok guys i reached the footing of the foundation, but now i can't see where the crack is going. i can see it 16" from the footing, it doesn't seem to go all the way down to the footing, is that possible for the crack to stop like that?

Do not make the mistake of using "dirt" (whatever that is) or clay for most if the backfill. - That only increases the pressure against the wall.

You apparently do not have the drain tile that should have been there, so you will have to make sure you keep water away from the backfill since it will never be as dense as the native soil on the site. You can "cap" the backfill with clay IF you have good gutters and long downspout extensions.

By your description, you have a typical shrinkage crack that is very common in poured basements, especially if the contractor used very wet concrete to make the job easier.
