10 Waterproofing Mistakes to Avoid in Your Home

Waterproofing is essential in protecting your home from water damage. However, it is not as simple as just applying a waterproofing product and calling it a day.

There are several common mistakes homeowners make when waterproofing their homes, which can lead to costly repairs and damages in the future. Today, we will discuss 10 of these waterproofing mistakes to help you avoid them and protect your home.


1) Not Addressing Existing Issues

One of the biggest mistakes homeowners make is not addressing existing issues before starting the waterproofing process. If there are cracks or leaks in your foundation or walls, these need to be properly repaired before waterproofing.

Otherwise, the waterproofing product will not be able to do its job effectively, and water can still seep through, leading to potential damage.


2) Choosing the Wrong Product

There are different types of waterproofing products available on the market, each designed for specific purposes and areas of your home. It is important to choose the right product for your particular needs.

For example, a product meant for exterior use may not work well indoors or vice versa. Make sure to research and consult with professionals before selecting a waterproofing product.


3) Incorrect Application

Even if you have chosen the right waterproofing product, it is crucial to apply it correctly. Improper application can lead to gaps or areas where water can still seep through.

Follow the manufacturer’s instructions carefully, and consider hiring a professional for application if you are unsure.


4) Neglecting Maintenance

Waterproofing is not a one-and-done solution. It requires regular maintenance to ensure it continues to protect your home effectively.

Neglecting maintenance can lead to the breakdown of the waterproofing product and leave your home vulnerable to water damage.


5) Not Checking for Proper Drainage

Proper drainage is crucial in preventing water from accumulating and seeping into your home. When waterproofing, it is important to check that your gutters, downspouts, and drainage systems are working properly.

If they are clogged or not functioning correctly, water can build around your foundation and compromise the effectiveness of your waterproofing.


6) Using Interior Waterproofing as a Quick Fix

Interior waterproofing may seem like an easy solution to address water issues inside your home. However, it should not be used as a quick fix for larger structural issues.

It is best to address the root cause of the problem and waterproof from the exterior for long-lasting protection.


7) Not Considering Landscaping

Landscaping can play a significant role in waterproofing your home. If your yard slopes towards your house, water can easily flow towards and potentially seep into your foundation.

Consider making landscaping changes to redirect water away from your home’s perimeter. Grading your yard so that it slopes away from your foundation is a critical step in this process.

Additionally, installing French drains or channel drains can help manage excess water and direct it towards a designated drainage area.

Planting native vegetation with deep root systems can also improve soil stability and absorb significant amounts of water. Be mindful of the placement of downspouts, ensuring they discharge water far from the foundation.


8) Not Waterproofing Before Finishing Your Basement

If you are planning on finishing your basement, it is crucial to waterproof before completing any renovations.

Otherwise, you risk having to tear everything down in case of water damage or waterproofing issues.


9) Using the Wrong Sealant

Sealants are often used in conjunction with waterproofing products to provide an extra layer of protection. However, using the wrong type of sealant can actually trap moisture and cause damage instead.

Make sure to use a sealant appropriate for your waterproofing product, and follow proper application methods.


10) Not Consulting Professionals

Waterproofing is not a DIY project that should be taken lightly. It is important to consult with professionals who have experience and knowledge in this area.

They can help assess your home’s specific needs and recommend the best waterproofing solutions for long-lasting protection.



Avoiding these common waterproofing mistakes can save you time, money, and headaches in the long run.

Be sure to address any existing issues, choose the right products, and consult with professionals for best results. By properly waterproofing your home, you can ensure its protection against water damage for years to come.
