Infographics about Where Basement Water Leaks Come from

Basement waterproofing solutions can include different services for different properties. The specifics will depend on your budget, the extent of water damage, the specific location of your home, and other factors. Our basement waterproofing services in Kitchener & Waterloo often include:

Exterior basement waterproofing is a process of waterproofing the foundation walls of a building from the outside. This method is used to prevent water from seeping into the basement or crawl space of a building, which can cause structural damage, mold growth, and other issues. The process of exterior basement waterproofing typically involves excavating the soil around the foundation walls to expose the entire wall surface. The walls are then cleaned and any cracks or voids are repaired. A waterproofing membrane or coating is then applied to the walls, which acts as a barrier to prevent water from penetrating into the basement. In addition to the membrane or coating, exterior basement waterproofing may also involve weeping tile installation around the foundation walls. This system is designed to collect and redirect water away from the building, further preventing moisture from entering the basement.

A sump pump is used to remove water that has accumulated in a sump basin or pit, typically located in the basement of a home or building. The sump pump is designed to automatically turn on when the water level in the sump basin reaches a certain level, and pump the water out of the pit and away from the building. It is important to make sure that the sump pump is properly maintained & services as a broken sump pump can lead to a basement flood.

Basement plumbing rough-ins & basement bathroom rough-ins are some of the most popular services along with new construction waterproofing. They involve our team of basement waterproofing contractors installing pipes and vents for the plumbing system in new construction projects. This service involves routing pipes through wall cavities, running vent stacks to the roof, laying underground pipes, and installing fixtures and end elements etc.

If you are experiencing wet basement problems or see foundation leaks on your walls, this could be a sign that you need a foundation leak repair. The first step is often foundation leak detection. Our teams are trained to deliver quality foundation leak detection & repair services and have all the necessary equipment with them. Let us find the leak in your basement & do the foundation crack repair to address it!

Installation of backflow prevention devices is a very important measure designed to prevent sewage backup into your basement. This will help protect your property from dangerous wastewater damage that is also costly to repair.

Interior basement waterproofing is a process of waterproofing the interior of a basement or crawl space to prevent water from seeping through the walls or floor and causing damage. Unlike exterior waterproofing, which is done on the outside of the foundation walls, interior waterproofing is done on the inside of the basement or crawl space. It is rather a water management technique as it doesn't prevent water from getting into the basement, but helps manage the water that already made it in.

Crawlspace encapsulation is the process of sealing the crawl space of a building with a vapor barrier to prevent moisture and other environmental elements from entering. The encapsulation process involves sealing the walls and floors of the crawl space with a heavy-duty plastic sheet or other barrier material, along with sealing any openings, such as vents or pipes.

Foundation repair refers to the process of repairing and stabilizing the foundation of a building that has been damaged or compromised. Foundation damage can be caused by a variety of factors, including soil movement, water damage, and poor construction practices. Some common signs of foundation damage include cracks in the walls or floors, sloping or uneven floors, and doors or windows that are difficult to open or close.

The foundation repair process typically involves an inspection by a professional contractor to determine the cause and extent of the damage. Depending on the severity of the damage, the repair may involve simple cosmetic fixes, such as patching cracks, or more extensive structural repairs, such as underpinning or the installation of support beams.

Basement walkouts are a popular service in Kitchener & Waterloo areas. This allows to transform your property basement making it a lot more convenient to use. Additional air flow, separate exit construction and the so-much-needed windows will be added to your space!

Foundation crack repair is the process of fixing cracks that have formed in the foundation of a building. Cracks in the foundation can be caused by a variety of factors, including settling of the foundation, water pressure, or shifts in the soil. When left unrepaired, foundation cracks can lead to basement water leaks, serious structural issues, as well as water intrusion, mold growth, and other problems. Therefore, foundation crack repairs should be done as soon as basement wall & floor cracks are detected.

Basement underpinning is the process that helps increase the strength of the foundation as well as lower the basement floors. Basement underpinning is a popular service in Kitchener & Waterloo area because it allow homeowners to add an extra floor of space to their house, thus increasing the amount of space and the value of their property.

A weeping tile, also known as a drain tile or french drain, is a type of drainage system used to prevent water from accumulating around the foundation of a building. Weeping tiles are typically made of porous plastic or concrete and are installed around the perimeter of the foundation, either inside or outside the building. The weeping tile works by collecting water that has accumulated around the foundation and directing it away from the building through a series of pipes. The pipes are typically connected to a sump pump or other drainage system, which then pumps the water away from the building.

Bench Footing

Bench footing is a technique that allows lowering the basement floor  without digging underneath the existing foundation. This allows you to add additional headroom in the basement for a lower price compared to underpinning, however will leave a "bench" which will take away some of the space in your basement. Talk to one of our experts today to discuss how bench footing can help transform your basement.

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.

Which Foundation Waterproofing Method is Right for you?

What is the Difference Between Interior and Exterior Basement Waterproofing for Kitchener & Waterloo Properties

Exterior and interior basement waterproofing are two different methods of preventing or minimizing water penetration through your basement walls and floors.


Exterior basement waterproofing involves excavating the soil around the foundation of the building, applying a waterproofing membrane to the outside of the foundation walls, and installing drainage systems to channel water away from the building. This method is more comprehensive and effective, but it can be more expensive and disruptive because it requires digging around the perimeter of the building.


Interior basement waterproofing is a water management solution, rather then waterproofing. It involves installing a waterproofing system on the inside of the basement walls and floors. This may include applying waterproof coatings or sealants to the walls and floors, installing drainage systems, and using a sump pump to remove any water that enters the basement. This method is less expensive and less disruptive, but it may not be as effective as exterior waterproofing as it is focused on managing the water that has already made it to your basement as opposed to preventing water from entering your basement in the first place.

The right solution for your property will depend on the extent of water penetration, your budget, location and other factors. We recommend talking to basement waterproofing contractors before deciding on the type of basement waterproofing for your property.
