Internal Basement Waterproofing Solutions in Windsor, Ontario

Interior foundation waterproofing redirects water that has leaked into basement areas out and away from the home. Interior drainage systems consist of pipes and drains that capture leaks or are built beneath the foundation to collect excess groundwater. This surplus water is sent to a sump pit, which is essentially a huge basin in your basement that retains water. 

Then there's the sump pump, a water pump that sits inside the sump pit and pumps water out of the basement and away from your house. Sump pumps typically start pumping water when it reaches a certain level in the sump pit. Most sump pumps have a backup battery to ensure that they can continue to function even if the power goes out.

When it comes to interior basement waterproofing, there is more than just one method. Investing in a good internal waterproofing system can significantly lessen the chance of a flood in your basement. Vapour barriers is a common method used to waterproof the inside of foundations. They are constructed of plastic or foil sheets and are installed around the walls of your basement to keep moisture out. For help with interior waterproofing in Windsor, contact our team today.

Common Interior Leak Problems

Floors and Walls

When water travels below the foundation footings, it can create wetness in the basement’s floors resulting in ruined flooring and mold. By setting up interior waterproofing, you include another drainage system to your home which helps to redirect water and therefore prevent water damage. This drain can intercept water running through foundation walls and under footings. We can additionally install a drainage membrane layer to make a barrier in between the foundation wall and your living space. This creates an additional layer of protection.

Sump Pump

As crucial as waterproofing is, water drainage is equally as essential. If water isn’t drained away correctly from your home, it can flow right back and cause issues again. A sump pump is a dug out pit in your cellar which is at the lowest point of your waterproofing system. There is a sensing unit which detects water build up and pushes excess water to beyond your home. Every one of the items we use are high quality to ensure they run successfully.

Different Interior Basement Waterproofing Methods

The great majority of Windsor, ON, homes lack waterproofing, that would protect your belongings and space from water damage. The good news is that if you want to waterproof your basement from the inside, you have a lot of options. These are some examples:

French Drains

French drains are one of the most effective methods of waterproofing your basement from the inside. These drains open up the floor of your basement, allowing any entering water to flow along streams. This keeps water from gathering in your flooring's corners or low locations. Once the water has been redirected, a sump pump will pump it out of your basement and away from the foundation of your home. Professionals can install a French drain and pump into your basement in one to two days. It is important to note that French drains are not sump pumps, however the two can be stacked for greater waterproofing.

Sump Pumps

Like its French relative, a sump pump will drain standing water from your property. Sump pumps, on the other hand, function on a motor and actively work to rid your basement of leaky water. If you want your sump pit to last, you must maintain it.


Installing a dehumidifier is your first line of protection against mold and long-term water damage. A dehumidifier removes humidity from the air. You'll have a dry basement once the worst of the humidity has passed. The type of dehumidifier you install in your home will determine the installation process. We recommend a self-draining unit to eliminate the need to empty buckets or reservoirs.


Another interior waterproofing method is using a sealing tool to seal your basement. Homeowners should note that this is only a temporary fix to a long-term problem. To waterproof your basement with an interior sealant, run the sealant around the perimeter of your foundation. With the sealant in place, the humidity levels in your basement should fall to the point where water no longer forms quickly, in good or bad weather. Sealing your basement can be done in a matter of hours.
