Can a very large driveway crack (s) that has made driveway concrete sink and lean towards the basement be the cause for water in basement? We only get water with very heavy downpours and only on one wall. We have been in house for years and never had water issues before, except last 1 1/2 - 2 years. I can't say how long driveway crack has been there; it started as a crack and has now sunk as wall. Multiple cracks I should add. We do have drain tile under that wall we believe. Interior wall where foundation meets garage wall. From post above I don't want to install a interior drain tile if fix could be driveway crack repair or snake drain tile. I really hope @BasementWaterproofer sees this to give me their opinion as well as any one else with experience/knowledge.

You didn't say how old your house is, or if the driveway is as old as the house, but if the driveway is sloping toward the foundation and there is one or more large cracks (that extend all the way through the concrete), that's very likely where the water in your basement is coming from.

While drain tile is great, it can sometimes clog, and when that happens, it's like having no drain tile at all. If you do have drain tile, it will drain into a sump pit and a sump pump will pump the water to the surface. Do you have an interior (under the basement floor) sump pit that services the exterior drain tile? Or perhaps an exterior pit (often under a window well)? If the pump is kicking on during the times when you receive heavy rain and flooding, then the drain tile is probably working, but it may not be able to keep up with the excessive water.

I don't blame you for not wanting to replace that exterior drain tile, or install interior drain tile. Those are both big (and expensive) jobs.

Have you talked to a slab-jacker? What they do is come in and inject material under the settled part of the driveway to raise it so it no longer slopes toward your house foundation. Then, they could seal the crack (might have to replace a portion of the slab near the foundation), and then the water would quit draining down by the wall.

That'd be less expensive.

You could also try just sealing the crack(s) and hoping for the best, although, if the driveway is settling now, it might continue to settle a bit more.

If I were in your shoes -- I'd try the least expensive method first -- just sealing the driveway cracks. Next, I'd bring in a slab-jacker, but, I'd put off interior (or exterior) drain tile because just sealing the cracks might stop the leakage.

Best of luck!
