I just bought a new house that was built on fill dirt that sat for maybe 6 months prior to building. The builder built 8 houses on this filled in area, 4 ranchers and 4 split levels with a full basement.
My neighbors that own the ranchers constantly have water in their crawl space. Even weeks after it rains the mud in the grawl space is soft and they seem to think it's coming from under the foundation.
My house has a basement, but I have recently noticed cracks in my basement:
If water is getting underneath my foundation - what possible problems could I have? Is the best way to fix it by install a sump pump?
