How Water Can Get into Your Basement

Finding water in your basement is never good, and it can be difficult to figure out where the water is coming from. There are many causes of basement flooding, though the most common is poor grading or sloping. When the ground surrounding your basement slopes downhill towards your basement, it forces your basement to act as a dam (, resulting in a buildup of pressure against the walls of your basement. The water continues to put pressure on the walls until it can find space to flow through. If there are any cracks - even tiny ones - in the walls of your basement, you'll end up with water in your basement.

Even if you don't have any cracks in your basement, the pressure from the water can create cracks or make small cracks even bigger, resulting in more flooding and more water damage.
