Interior Basement Waterproofing Solutions for a Safe and Dry Home

Interior waterproofing is a cost efficient and excellent way to internally protect your basement. It redirects water that has seeped into basement areas out and away from the house. Interior drainage systems are made up of pipes and drains that are placed beneath the foundation to collect excess groundwater or to absorb leaks. This excess water is directed to a sump pit, which is simply a large basin in your basement that collects and stores water. 

Another option is a sump pump, which is a water pump that sits inside the sump pit and pumps water out of the basement and away from your property. Sump pumps typically start moving water once a certain level in the sump pit is reached. Most sump pumps feature a backup battery to ensure that they can keep working even if the power goes out.

When it comes to interior waterproofing, there are several options. Investing in a robust internal waterproofing system will considerably reduce the likelihood of a basement flood and leaks. Vapour barriers are a popular approach for waterproofing the inside of foundations. They are made of plastic or foil sheets and are put around the basement walls to keep moisture out. 

Internal waterproofing services are also cheaper than exterior waterproofing solutions and it still does a great job. Our waterproofing contractors can inspect your home and determine which solution will give you the best long-term protection. Whether that may be exterior waterproofing or one of the many interior waterproofing methods.

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.

Difference Internal Waterproofing Methods

The vast majority of homes in Sault Ste. Marie, ON, lack waterproofing, which would protect your things and property from water damage. The good news is that there are numerous solutions for waterproofing your basement from the inside. Here are a few examples:

French Drains

French drains are one of the most effective techniques of internally waterproofing your basement. These drains open up the basement floor, allowing any water that enters to travel along streams. This prevents water from collecting in your flooring's corners or low spots. Once the water has been redirected, a sump pump will pump it out of your basement and away from the foundation of your home. In one to two days, a professional can install a French drain and pump into your basement. It should be noted that French drains are not sump pumps; nonetheless, the two can be stacked for increased waterproofing.

Sump Pumps

A sump pump, like its French cousin, will remove standing water from your property. Sump pumps, on the other hand, use a motor to actively remove water from your basement. You must maintain your sump pit if you want it to last.


A dehumidifier is your first line of defence against mold and long-term water damage. A dehumidifier is a device that removes humidity from the air. Once the worst of the humidity has passed, you'll have a dry basement. The installation method will be determined by the type of dehumidifier you choose to install in your home. To avoid having to empty buckets or reservoirs, we recommend a self-draining device.


Another interior waterproofing technique is to seal your basement using a sealing tool. Homeowners should be aware that this is merely a short-term solution to a long-term issue. 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 be reduced to the point that water does not develop quickly in good or bad weather. Basement sealing can be completed in a matter of hours.

Interior Foundation Waterproofing in Sault Ste. Marie

Having a damp basement is a health risk to your family an a threat to the structure of your home. By protecting your basement with waterproofing solution, you can rest assured your home and family are safe.

Interior waterproofing is one of the only ways to get rid of excess moisture in your basement. It helps you transform your basement into functional square-footage by removing the opportunity for water leaks.

This procedure functions by adding drainage to the inside of your home. Your flooring by the outside walls will be ripped up and a drainpipe will be installed. This drain will gather water from under your foundation and redirect it to the sump pump. The sump pump than disposes of the water away from the building. The interior solution should be utilized when:

  • The external approach can not be used because of the lack of accessibility outside or for any other reason
  • Pressure is the primary reason for water leaks
  • You have water leakage and have an incomplete basement (save money on not having to tear up a finished space)
  • The interior floors and walls can be easily accessible
  • Can be finished quicker than an external approach
