How Exterior Basement Waterproofing Works? 

Exterior Waterproofing System is installed outside the basement walls and helps minimize the interaction that your foundation walls have with groundwater.

Process of Exterior Basement Waterproofing:

  • Exterior Basement Waterproofing involves the excavation of the soil surrounding the foundation to expose the walls

  • Walls are then cleaner and foundation cracks are repaired

  • Multiple layers of basement waterproofing membrane are applied to the walls

  • Drainage system is installed to help reduce the amount of groundwater accumulated around the foundation

  • The trench is then backfilled following a special methodology

  • Landscaping work is done

Benefits of Exterior Basement Waterproofing

  • Helps minimize contact between groundwater and the foundation walls, this helps protect the foundation from structural damage.

  • Actually prevents water from entering the basement

  • Doesn’t require maintenance, unlike internal basement waterproofing

Downsides of Exterior Basement Waterproofing

  • Exterior Basement Waterproofing projects often cost more compared to interior waterproofing

  • External waterproofing takes longer to complete

  • Is more disruptive as it involves excavation around the foundation


Factors that Impact Basement Waterproofing Cost in Toronto

Factors we Look at When Estimating the Cost of Basement Waterproofing in Toronto & GTA

  • Waterproofing Method – exterior basement waterproofing is often more expensive.

  • Scope of Work – basement waterproofing projects can include a number of other services – window well installations, basement underpinning (floor lowering), etc. The more services included under basement waterproofing, the higher the cost will be.

  • Depth of the Foundation – foundation depths in Toronto generally range between 5 and 8 feet. Deeper foundations require more labor and materials, which results in a higher cost of basement waterproofing.

  • The Extent of the Damage – before we start your project, our team will examine your foundation to determine the extent of existing damage. Small basement wall cracks can be repaired using relatively inexpensive materials such as epoxy injection. More extensive foundation repairs (such as foundation reinforcement) are more complex and increase the cost of basement waterproofing.

  • Materials – if your basement waterproofing projects only involve foundation crack repairs cost of materials will be lower compared to interior waterproofing or exterior waterproofing.

Basement Waterproofing Reviews

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.

Aqua Master quoted me a very fair price for waterproofing and finshed the job ahead of schedule. We haven't had any water issues in our post-war hm since then. Highly recommend this business for its professionalism and quality of work. Hire with confidence!
