What can be Included in Basement Waterproofing Mississauga?

Basement Waterproofing Services Infographics

When it comes to basement waterproofing, there is no one-fits-all approach. During the free basement waterproofing assessment our experts will design the best solution for your specific case. Our teams are trained to develop basement waterproofing scopes based on sources of water leaks, the extent of water damage, the amount of groundwater in your area, your plans for the property, your budget and more. When designing the waterproofing solutions there is a number of services we pick from, here is a couple of examples.

Exterior basement waterproofing is a method of preventing water from seeping into a basement by applying protective measures on the outside of the foundation walls. It typically involves excavating the soil around the foundation, repairing foundation cracks, applying a waterproof coating or membrane to the walls, and installing a drainage system (weeping tile installation) to redirect water away from the basement. This approach helps to create a barrier against moisture and prevents water accumulation, thereby protecting the basement from potential leaks and water damage.

Exterior Waterproofing Cost Mississauga - $100-$300/linear foot

Basement Underpinning (Floor Lowering)

Basement underpinning is a construction technique used to strengthen the foundation or increase the depth of an existing basement or foundation. It involves excavating the soil beneath the foundation and extending its depth or providing additional support. Basement underpinning can be done using a variety of methods depending on the specifics of your project. 

Flood Cleanup Services

The main goal of flood cleanup services is to minimize damage and prevent the growth of mold and bacteria by quickly removing standing water, drying out affected areas, and cleaning and disinfecting surfaces.

Some of the services that may be included in a flood cleanup package include water extraction, dehumidification, carpet cleaning, upholstery cleaning, structural drying, mold remediation, and odor removal. 

Weeping tiles, also known as drain tiles or perimeter drains, are necessary to manage groundwater and prevent water accumulation around the foundation of a building. They act as a drainage system, collecting water and directing it away from the foundation, helping to prevent water damage, basement flooding, and potential structural issues.

Internal waterproofing is a technique used to manage water infiltration within a basement by implementing measures inside the structure. Instead of addressing the issue from the exterior, internal waterproofing focuses on controlling water that has already entered the basement or is likely to enter through cracks, gaps, or hydrostatic pressure. A typical interior basement waterproofing project can include applying sealants or waterproof coatings on the interior walls, installing interior drainage systems such as French drains or sump pumps, and using vapor barriers to prevent moisture from seeping through the walls or floors. These measures help to collect and redirect water away from the basement, protecting it from potential water damage and minimizing the risk of mold growth or structural issues.

Interior Waterproofing Cost Mississauga - $70-$350/linear foot

Cracked basement wall, and cracked basement floor will almost 100% lead to water leaks or even worse. After the basement cracks are detected, we will go for foundation crack repair. Foundation cracks will be injected with an epoxy resin solution that bonds the pieces of the concrete foundation together.

Foundation Crack Repair Cost Mississauga - $1,500-$3,200

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 Aquamaster 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.

Sump pump installation is important for effectively managing water accumulation and preventing basement flooding. A sump pump is a mechanical device installed in a pit (sump) in the basement floor. It works by automatically detecting and pumping out water that collects in the sump pit.  Sump pumps can be a part of interior basement waterproofing projects.

Sump Pump Installation Cost Mississauga
- $500-$3,600

Window Well Installation

Window well installation involves creating a protective structure around basement windows to allow natural light to enter and facilitate emergency egress. It typically consists of excavating the soil around the window, installing a retaining wall or window well liner, and providing proper drainage.

Window Well Installation Cost Mississauga - $1,600-$4,000

Should you Choose Interior or Exterior Waterproofing?

Understanding Exterior vs Interior Basement Waterproofing

Interior and exterior basement waterproofing are two different approaches to preventing (exterior) or managing (interior) the water that makes it to your basement. Here's a brief explanation of both waterproofing methods.

Interior Basement Waterproofing - involves addressing water issues from within the basement. It focuses on managing water that has already entered or is likely to enter the basement through cracks, gaps, or hydrostatic pressure.

The details will vary, but an average interior basement waterproofing project can include:

  • Crack Repair - Identifying and sealing cracks or gaps in the basement walls and floors using sealants or waterproof coatings.

  • Drainage - Installing interior drainage systems, such as French drains or drain tiles, along the perimeter of the basement to collect and redirect water to a sump pump.

  • Sump Pump Installation - Installing a sump pump to remove collected water from the basement and discharge it away from the foundation.

  • Waterproofing Membrane - is installed to help direct water that made it to your basement towards the sump pump that will push the water out.

Exterior Basement Waterproofing - addresses water issues from the outside of the foundation walls. It focuses on preventing water from entering the basement in the first place by creating a barrier against moisture.

Specifics will vary, but here is an example of a generic exterior basement waterproofing project:

  • Excavating the soil around the foundation to expose the exterior walls.

  • Repairing wall cracks - basement waterproofing contractors will repair newly discovered basement wall cracks.

  • Applying a waterproof coating - or membrane to the exterior walls to create a protective barrier against water penetration.

  • Drainage - installing weeping tiles or drainage boards, along the foundation walls to collect and redirect water away from the basement.

  • Backfilling - the excavated area with gravel or other suitable materials to promote proper drainage.

Both interior and exterior basement waterproofing have their advantages and are often used in combination for comprehensive waterproofing solutions, depending on the specific needs and circumstances of the building.

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.
