If you’ve ever walked down to your basement only to find pooling water or in the worst-case scenario, a flood, chances are you don’t know what to do next. Homeowners in Raleigh and Wilmington are no strangers to the heavy amounts of rain in the spring which can bring upon wet or leaky basements if not properly protected.

Common Causes of Basement Problems

Your wet basement and other basement damage can stem from a variety of sources. Here are some of the most common causes of basement water intrusion and damage, as well as how you can prevent it from happening again in the future.

The Clay Bowl Effect 

After your foundation, basement, walls, and floor were in place, builders backfilled the gap around your newly constructed home with the excavated soil. If the soil placed around your foundation wasn’t properly compacted beforehand, you may experience the clay bowl effect. This can wreak havoc on your home when water saturates the soil and presses on your foundation walls. Heavy rain can wash soil away and your foundation is at risk of cracking or shifting. This can lead to water having easy access to your basement.

Hydrostatic Pressure

One of the main culprits of basement water damage that can also play a role in the clay bowl effect is hydrostatic pressure. Hydrostatic pressure is caused by soil becoming oversaturated with water, which then results in immense amounts of pressure being put on your home. This can lead to bowing basement walls, that can crack and let water seep into your basement. The cracks can grow wider over time and allow vast amounts of water to pour in. Hydrostatic pressure can also compromise the structural integrity of your home if not handled properly.

Interior Leaks  

Chances are most of your plumbing pipes lay within your basement. Old pipes, frozen pipes, unintentional movement, or even rain and flooding can all lead to water in your basement. In areas such as Boone where the temperatures will sometimes drop below freezing in the winter, any older pipes that freeze can end up bursting and cause thousands of dollars in damage. It’s important to regularly check on any older plumbing appliances in your home and make repairs if necessary. This can also be one of the more costly things to deal with as plumbing failure mixed with basement damage is no easy task to fix.
