1. Look at the slopes above you and see which way they're going.
If you live on a hill or a mountain, pay attention to how the slopes are heading. If there is a slope down to the building, rainwater may flow down the mountain and through the basement.
Even if the slopes are pointing in the right direction, rock slides could also occur. To brace for the risk, you can need to purchase a costly homeowner's insurance policy. Check with the nearest municipal building to see if rockslides are likely, so you're aware of the dangers.
