The 7 Most Common Basement Waterproofing Mistakes and How to Avoid Them


If you are like most people, you’re probably not aware of the 7 most common basement waterproofing mistakes and how to avoid them. And if you have a basement, it’s important to make sure it is properly waterproofed so that you can protect that investment. Unfortunately, many people make common mistakes when waterproofing their basements, which can lead to expensive repairs down the road. This blog post will discuss the 7 most common basement waterproofing mistakes and how to avoid them!

Waterproofing Basements with Waterproofing Paint

One of the most common mistakes people make when waterproofing their basement is using waterproofing paint as their sole method of protection. Waterproofing paint is designed to be a barrier against water but is not 100% effective. It can often crack and peel over time, leaving your basement vulnerable to water damage. If you use waterproofing paint, use another form of waterproofing, such as sealant or membrane, for added protection.

Not Repairing Cracks in the Foundation

Another common mistake people make is failing to repair cracks in their foundation before waterproofing. It’s important to remember that cracks in your foundation can allow water to enter your basement, regardless of how well you waterproof it. Therefore, it is essential to repair any cracks in your foundation before waterproofing your basement.

Failing to Install a Sump Pump

If you live in an area with a high water table, installing a sump pump in your basement is essential. A sump pump will help remove water entering your basement so that it does not cause damage. Many people think they don’t need a sump pump because they don’t have flooding issues. However, even if you don’t currently have flooding issues, a change in the water table could cause problems in the future. It’s better to be safe and install a sump pump now than wait until you have costly flood damage later on.

Draining Flooded Basements Too Quickly

If you’ve ever had a basement flood, you know the first thing you want to do is get all the water out as fast as possible. But if you have a sump pump that does the job too quickly, it can cause more problems than it solves.

The soil around your foundation is constantly absorbing and releasing moisture. When you suddenly remove a large amount of water from the soil, it can cause the ground to settle unevenly, which can lead to cracks in your foundation.

To avoid this problem, slowly drain your flooded basement over several days. This will give the surrounding soil time to adjust and help prevent any long-term damage to your foundation.

Not Allowing Proper Drying Time after a Flood

One of the most common basement waterproofing mistakes is not allowing proper drying time after a flood. This can lead to mould and mildew growth, which can cause serious health problems. If you have had a flood, dry out your basement completely before attempting to waterproof it.

Not Being Aware of Soil around the Home’s Foundation

One of the most common waterproofing mistakes is not being aware of the soil around the home’s foundation. It’s important to have proper drainage away from the house to avoid basement leaks. If there is water pooling next to your home, it can eventually seep into your basement. Improper grading and landscaping are often to blame for this problem. Luckily, it’s usually a fixable issue. You can add drainage systems or make changes to your landscaping to redirect water away from your home.

Ignoring Potential Runoff Locations

One of the most common mistakes people make is not taking potential runoff locations into account. Water will naturally flow toward the lowest point in your yard when it rains. If you have a basement, that’s usually where the water will end up.

You can avoid this problem by redirecting runoff away from your house with gutters, downspouts, and French drains. These simple solutions can go a long way in keeping your basement dry.
