If a foundation is properly set on the right soil, the house sits on a crown so water flows away and the gutters and drainage all properly work, your basement should be dry all of the time. Now,
even if all of these things are true when a home is constructed, it can change over time. To
guarantee a dry basement all of the time, you will have to make sure all of these factors remain
intact over time, requiring extra viligance. Even the best viligance, however, won’t be able to
catch everything, especially changes to the soil alongside and beneath your home, though
proper drainage can go a long way to preventing these changes.
