Water Coming In to Basement

The one time flexseal didn't work....lol.

You need to call a professional and get this taken care of from the exterior or the home, not interior

Can you figure out what is going on outside as the source of water? We bought a house four years ago that had water leaking in the basement on two walls. One I determined was the water main leaking just a couple of feet from the house. At the water meter 400' away from the home entrance I determined there was a significant leak somewhere losing 1 gallon every 7 minutes. The ground was sandy limestone and draining the water where I couldn't find the leak bubbling above ground through the wooded area to our house. I hired American Leak Detector and they determined the leak was just outside the entrance into the basement wall. That was a pretty easy fix.

The other wall with a basement leak was due to crunched underground 4" thin wall PVC pipes connected to the gutter downspouts and diverting rain water about 40' away from the house to a dry creek bed. When it rained hard, I could see water bubbling out of 3 gutter downspouts and down the foundation wall. I put a snake camera into the 4" PVC pipes where they emptied out in the yard into the creek bed. I could see where the thin wall PVC pipes were flattened and causing the problem. That was a lot harder to fix. I dug down to all of that crushed pipe and uncovered the crushed pipes for a good portion of the overall trench length and just decided to replace all of the pipes all the way to the gutter downspouts. I had to temporarily relocate quite a few nice bushes and move them back after I replaced all of the pipes with 4" PVC pipes, but with schedule 40 instead of the thin wall PVC.

At our previous house, we had a small leak into our basement where the ground was fairly flat. I checked out the ground at the house near the leak and noticed several chipmunk holes, a sunken area and the ground at the house pulling away slightly from the wall. I dug the ground up around the chipmunk holes and sunken area and then packed in dirt and tamped it down good. Then I put about 20' of some clay up against the house to about a couple of feet away and around the perimeter of that area near the leak and sloped it away from the house. That stopped the leak. Later, for good measure, I put some hydraulic cement in the basement floor joint and painted Dry Lok on the inside wall.

Not saying you have issues like I did, but perhaps you can identify the source of the water and fix it outside. If the basement leak is on a wall where the outside ground slopes into the house, you might need to install a French Drain.
