You haven't told us what the age of the house is or where you are located but here's the thing: if you have an old house and you are getting water through your walls, it's likely related to your (now defunct) drainage.
Back in the middle of the 20th century, a lot of homes were built in the US. At the time, they used porous ceramic drainage pipes. This is why people call plastic drainage pipes 'drain tile' to this day. I remember as a child digging in my (parent's) yard and finding these bits of ceramic. They were crushed 'drain-tile' pieces.
The standard design of such systems was to lay this porous 'drain-tile' around the foundation or a home. The idea was that if any water drained towards the foundation, it would seep into the system and be routed away. This was probably a fairly effective approach as long as the system drained to somewhere.
Here's where the problem comes in. Those bits of ceramic I was finding in the soil were from the drain tile but not the part next to the foundation. What I was finding was the remnants of the part of the system that was supposed to take the water away. The ground shifts. Tree roots crush clay pipes like twigs under a truck tire. What these homes are left with is a porous pipe wrapped around the foundation with nowhere to drain to or at least it doesn't drain well. And to top it off, a lot of these homes have downspouts that run into this weeping pipe up against the foundation.
The water has to go somewhere and that somewhere is your foundation. A lot of people will see water coming in and think, "I need to waterproof my basement from the inside." I personally think this is a dumb idea. The goop that is coming in is likely a mix of water from the outside and whatever chemicals have been applied to the walls.
What's the answer if you are in this situation? Call a landscape company that does drainage. They will reroute the water away from the foundation. It probably won't be cheap so get a few estimates and make sure they are legit. You might even want to dig up the clay tile around the foundation and get rid of it.
