What is Interior Basement Waterproofing?
Basement waterproofing approach designed to manage water that has already made it to your basement. In some cases, exterior basement waterproofing is just not feasible due to high cost, or other reasons like too small of a distance between your & your neighbor’s houses.
This is where interior waterproofing can help protect your property from basement leaks & water damage. It involves implementing various techniques and systems to manage water that may enter through the walls, floors, or foundation of a basement.
During heavy rainfalls, snow melts outside water will be pushing foundation walls, looking for a weak point to enter the basement.
That’s exactly where interior waterproofing comes in. It works by collecting the water that has already made it to your basement and redirecting it to the sump pump. Once the water reaches a certain level, the sump pump activates and pushes the water outside of your property.

Can You Do it Yourself?
How Easy is it to Install an Interior Waterproofing System?
Despite being less complex compared to exterior waterproofing, it is still fairly hard for non-expert to accomplish. A lot is at stake – will the waterproofing system properly collect the water, will the sump pump work etc.
Waterproofing is supposed to protect your property and give you peace of mind. That's why we recommend hiring professionals to take care of the internal waterproofing projects for you. Especially if you are planning to renovate the space. This will give you peace of mind that the work is done professionally and the chance of something going wrong is minimal.

Interior Waterproofing May Include
What is Included in Interior Waterproofing Systems?
Every project is unique, there is no one-fits-all approach. However, here is an example of what an average interior waterproofing setup may include:
-
Crack repair - cracks in the basement walls or floor can be potential entry points for water. Interior basement waterproofing may involve filling these cracks with sealants or epoxy injections to repair the cracks and prevent water seepage.
-
Basement sealing – this is where contractors apply multiple layers of waterproofing materials to interior basement walls and floors. This process can involve waterproof coatings, sealants, or membranes to create a barrier against water intrusion. These materials help to prevent moisture from seeping through the porous surfaces and direct it to the sump pump.
-
Interior drain tile system - this involves installing a drainage system along the perimeter of the basement floor. The system collects water that seeps through the walls or floor and directs it to a sump pump or a gravity drain.
-
Sump pump installation - a sump pump is typically installed in a basement to collect and discharge water away from the foundation. It helps prevent water buildup and flooding by automatically pumping out water that accumulates in the sump pit.
-
Dehumidification - moisture control is an important aspect of basement waterproofing. Installing a dehumidifier helps to reduce humidity levels in the basement, preventing the growth of mold and mildew and creating a more comfortable environment.
It's important to note that interior basement waterproofing focuses on managing water that has already entered the basement. If water issues stem from external sources, such as poor drainage, grading, or foundation cracks, it may be necessary to address those issues through exterior waterproofing methods to prevent water from reaching the basement in the first place.

What Our Clients Say?

Stephanie G.
Residential Client
I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.
The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
