We had our walls braced last summer and the basement guys had to drill holes in the floor to push the walls back in to place. They patched up the holes with concrete and I've noticed a few times (almost immediately after) those patched holes were a bit moist and today discovered one of the holes has pooled a small bit of water around it. Quick google search indicates that since concrete is porous this can happen especially if you live in a humid area (we live in WI and it's been a super humid summer - today is exceptionally humid and muggy)
The rest of the floor was previously sealed so I'm guessing this is why it's only happening in the areas they drilled and patched? What's the best course of action here? Our dehumidifier hasn't been working it seems like (runs but not doing anything) so was already planning to buy a new one this weekend. Other that that I'm thinking we should just re-seal those areas with waterproof concrete floor sealer? Should that solve the issue or it there something more we need to do?
Our basement is pretty cool on average even in the hot/humid summer and with our dehumidifier not working it's just been getting increasingly more damp feeling down there. (I didn't notice how bad until I was re-organizing the basement the last few days).
I already called and left a message for our contractors who worked on the basement last year asking why this would happen, what we need to do and if this covered under the warranty. We just had new drain tile put in along 1 wall and 2 walls excavated & brace less than a year ago so I know it's not coming from the walls.
Any advice would be much appreciated!
