Any basement water problem experts here?

Good luck!

The Drylock is an option. BUT.... If the wall is unstable in the very least, and can move with the pressure in the least (even movement that you cant really see to measure), the cracks WILL reappear thru the interior coating. I know from personal experiences!! My town is called Springville, because of the springs! I have two that flow from my property, And I have a small cellar under the house that the original builder should have never put there!!! I have at least one spring that puts water into the cellar in periods of heavy rain. There is enough pressure under the slab that pencil lead size streams will spew up several inches high thru several cracks where two slabs join. I've sealed, I've opened the seam some to make a bigger seal, I've used "dam-tite" (like dry-loc) and other similar interior sealers. They all eventually fail at the seam/crack, since the pressure WILL make enough movement to re-open the crack. My cellar is completely inside the crawl space, and the concrete block walls do not go all the way to the floor joists. The only way to french-drain it means kneeling under the house with a short-handle pick and shovel to dig around the walls to the footing level, and then to dig a trench to the exterior wall (and then out to a lower level outside) for the drain to exit. Not happening for a 50+ year old fat boy!! BTW, the previous owner sealed the inside walls of concrete block walls with some type of GOOD sealer, up to the top. Yeah, that worked good. The sealer keeps the water in the concrete block (it still bubbles up from the floor, though). However, eventually, the water in the walls gets high enough that it runs out of the top of the blocks!!!! So, the water eventually finds a way out! That's what water pressure will do!! Sealing the interior walls and cracks might stop the current leaks. But don't look for that as long term, and don't be surprised if the water finds (or makes) a new path inside!

I've seen hundreds of houses where interior sealer was applied, and have seen large areas of the sealer flaked off the wall where the water simply pushes a layer of the surface off that the sealer was adhered to, and it comes off in small to large patches. If the water pressure is present, it WILL find a way in, eventually. And that much water in your basement..... That can lead to mold on your wood floor support structure just like too much moisture leads to mold on your cigars. (I hope you are using a dehumidifier in the basement).

I wish I could tell you that surface applications could do the trick. But they only help when you are talking about very small areas and very limited amounts of water. Your pictures say you are looking at large amounts of sub-surface water that you need to drain away from the outside.
