Wet soil coming through basement foundation walls?
I am hoping for some expert advice out there. A resale purchase is about to close in December and I happened to be at the property yesterday for a walk-through of the basement.
A home inspection was already conducted a few weeks ago and this issue was not detected at the time.
Initially, I thought someone had cleaned something dirty in the basement shower as I saw a dirty "soil like substance" on the shower floor.
But after a few additional visits to the property over the last few weeks, I noticed the soil-like dirt is getting progressively worse. It's also located behind the toilet. I went out to check the foundation and noticed a crack in the same vicinity.
Can anyone tell me what this is? And why am I also seeing it in the shower area?
I'm assuming it's soil and water that is penetrating through the foundation, but I'm not an expert here. I'm obviously also concerned about possible mold.
Let me know if you have any thoughts and suggestions on how to resolve this.
