water seeping into basement only in one spot


Out of a 1,800 sq ft basement, there is only one! spot where water is seeping in... and its in a corner too...

the corner that it is on is a T shaped corner... the top part is the foundation for the garage that is about 7ft above the garage slab level... backfilled and slabbed over (the garage that is)...

the left hand side of the T is the outside and the right hand is the basement which goes 7' below grade and is 1' above grade...

now there is no water coming in on this corner fro the first 4 ft down from the top of the cinder block foundation... (the blocks are 8 inch deep block) but right where the water starts to show up the grout is inset... about 1/4" and looks like there might of been a crack in the grout line or something (its a vertical grout line) and its right in the corner almost like they didnt put enough grout in... from that point down anytime it rains the walls get damp... they dont drip, they are just "wet" looking...

any way this can be fixed? could new grout be put into that hole and fix it? it seems like the water is coming out of the spot where the grout is of lower quality or missing some

It is always advisable to stop the water at the source. "Why is there water around the foundation?" First and foremost is to make sure the ground is sloped steeply (IMO) away from the house. Also, ensure that gutters and drain spouts, if used, are working properly and water is being diverted well away from the house. Dry dirt won't seep. If all else fails, dig it up and fix the outside of the wall. GL. j

there actually is no cracks on the outside wall below grade... which is the odd part... and the ground after being placed back is at a good slope and is packed clay... down spouts are fine it seems also

Well, if the wall is sealed and there are no cracks, from whence cometh thy water? You mentioned a possible crack where the grout looked inset, almost like there was not enough grout. The culpret? Dunno, but I'd sure clean and seal the heck out of that whole area. Water can be sneaky. GL. j

I have no idea... but if you wanta mystery my neighbor has a garage wall (plaster) about 2 ft above the garage slab and it is soaked only in a 1 ft diamater area... nothings behind or above it that would cause it to get wet... but it is consistnatly wet... and the plaster bubbled out only in that area...

Concrete can apparently wick water to a height of a few miles, theoretically, according to an individual on a different forum. That is why he and others paint the footers before the foundation wall is poured, and then the foundation wall before anything is installed above it. He uses UGL's (ULG?) DryLok latex masonry paint. Maybe you guys have a wicking problem??? Spooky.

The water table may be higher than you think and it just happens to cause seepage in the spot where you observed. Note: The water table can vary even in a span of just twenty feet. You may need a foundation drain system and sump pump. If the walls "look wet" in just a small part of your basement you can procrastinate in installing the drain system all the way around the perimeter.

the house was built with two sump pumps one inside and one outside along with the whole under slab / footer drainage system... thats what has me so confused because the entire rest of the basement is dry except that one corner...

I would use a brick chisel & hammer to chisel out any loose mortar in that area & tuckpoint the joint back in nice & tight.

Generally, water can travel fairly far before leaking into the basement, so you can't always look immediately outside the problem area for the problem. Sometimes you have to investigate 10'+ each way to find where it's leaking in.

With that being said, and the fact that the water seems to be leaking so high, I think you can just try patching the inside problem area first & let the interior cavity of the block do it's job of draining. Hopefully, the cavity drains into the bleeder tile, but it's tough to guess at that.
