Why do basements flood?

Rain and water pooling around the foundation are two leading causes of flooding basements. Basement flooding is most often caused by rain, particularly during heavy rainfalls or hurricane season. Hydrostatic pressure is when water seeps into your soil and pools around your foundation. With enough stress and repeated rains, all that water can add a lot of pressure and weight to your foundation. This can quickly lead to a path of least resistance, which could eventually lead water in the wrong direction: into your basement.

Other causes of flooding basements

Your basement may flood even if it’s not rainy season. These are just a few of the reasons basements can leak.

Problem with your Foundation’s Drainage

Your drainage system should be installed to divert water from the foundation and basement. A foundation drainage system that is not maintained properly can fail over time. Some houses might even be built without one. One of these situations can lead to water pooling, allowing water to seep through cracks and eventually flood your basement.

Failure of the Sump Pump

Sump pumps are responsible for pushing water away from your foundation. However, if your sump pump fails, especially during bad rainy days, the water from your sump pit could instead flood your basement.

Sewer Backup

This is the worst scenario! Rainwater can overflow your city sewers and cause a sewer backup. This happens when sewage backs up into your home through your floor drains or toilet. This overflow will most likely affect your basement floor drains. Because of the harmful bacteria found in sewage, this can prove to be very dangerous.

How to fix the problem

It doesn’t matter if you have experienced flooding or are concerned that flooding may occur under certain conditions. It is crucial to get the problem fixed as soon as possible. A flooded basement can cause severe damage and cost a lot of money. Finding the right solutions will save you time, headaches, and money. These are the solutions to waterproof your basement, depending on whether there is flooding.

Foundation Cracks

Cracks in your foundation can cause water damage and make it impossible to heal on its own. The best way to make sure your foundation is safe and sound for basement waterproofing is to hire a professional.

Basement Floor Drains

Although there is no way to prevent sewer backups, there are things you can do to reduce the amount of sewage that floods your basement’s floor drains. You can stop sewage from leaking into your basement by installing a one-way drainpipe. To ensure it works properly, you must regularly clean and inspect your drain plug.

Sump pumps

It is crucial to have your sump pump repaired by a basement professional if it has become damaged. Ensure you check the warranty on your sump pumps and inspect it regularly. A basement repair specialist can install a battery backup for your sump pumps. This will ensure that your sump pumps will still push water away from your house even if your electricity goes out.


Poor grading can cause water to pool or move around your home in a way that is not optimal. Talk to a professional landscaping company about your grading issues and how to create a slope.

Gutters and Downspouts

Make sure you clean out your gutters and downspouts every so often. Water flows away from your house through gutters and downspouts.
