Waterproofing Your Basement: Exploring Options and Solutions

A dry, well-maintained basement can be a valuable addition to any home, providing extra living space, storage, or even a rental income opportunity. However, basements are also the most common area of the home to experience water damage. To keep your basement dry and protect your investment, consider these different types of waterproofing methods.

Interior Water Drainage

Interior water drainage is one of the most commonly used methods of waterproofing basements. This system captures water that makes it through the walls or floor and channels it away. It's typically less expensive than exterior waterproofing, and it's highly effective when installed correctly.

Interior drainage systems often involve the use of a sump pump. A sump pump collects excess water in a sump basin and pumps it out of your home, preventing it from causing damage. This is an excellent solution if your basement is prone to flooding or if you live in an area with a high water table.

Exterior Waterproofing

This type of waterproofing involves excavating around your house to reach the full depth of your home's foundation walls. After this, a waterproof coating or membrane topped with drainage panels is installed. This method prevents water from making its way into the basement in the first place.

One type of exterior waterproofing that's particularly effective is the installation of exterior drain tiles. These are essentially perforated pipes that go around the perimeter of your home's foundation. They collect water that would otherwise end up in your basement and divert it away from your home. While this method can be costly and labor-intensive, it's considered one of the most effective waterproofing solutions.

Crack Injections

If your basement's water issues stem from cracks in the concrete walls or floors, crack injections might be the solution. This process involves injecting either epoxy or polyurethane into the cracks. The material then hardens, sealing off the crack and preventing water from seeping in.

Waterproof Primers and Paints

Waterproof primers and paints can be applied to the interior walls and floor of your basement. While these products can't fix existing water problems, they can help prevent moisture from seeping through the porous concrete and into your basement.


While not a form of waterproofing, dehumidifiers can help manage the moisture level in your basement, preventing dampness and the growth of mold and mildew. They are particularly useful in basements that are damp but don't have significant water intrusion issues.

Exterior Drain Tiles

Exterior drain tiles represent a robust and effective solution for basement waterproofing. Essentially, these are perforated pipes that are installed around the perimeter of your home's foundation. Operating on a simple yet effective principle, these tiles collect water that would have otherwise found its way into your basement and channel it away from your home. Even though the installation process might be labor-intensive and somewhat costly, the sheer effectiveness of this method in preventing water intrusion makes it a worthwhile investment for homeowners.
