Foundation Waterproofing 101: A Overview for Homeowners


Knowing where to start when it comes to waterproofing a foundation can be daunting for homeowners. The foundation, being the structural backbone of any home, requires ongoing care to safeguard against water damage, which can compromise the integrity of the entire building. 

Our goal with this article is to equip homeowners with the knowledge to make informed decisions regarding the protection and maintenance of their homes.

Understanding Foundation Waterproofing

Foundation waterproofing involves a series of measures aimed at preventing water from penetrating the basement or foundation of a house. The process not only addresses visible leaks and dampness but also tackles the underlying issues that cause water ingress. Effective waterproofing preserves the structural integrity of your home, prevents mould and mildew growth, and maintains a healthy indoor environment.


Why Is Foundation Waterproofing Necessary?

Water infiltration can lead to a plethora of problems, from minor inconveniences to major structural issues. The freeze-thaw cycle in Southern Ontario’s climate exacerbates these problems, making waterproofing not just beneficial but essential for the longevity of your home. Here are several reasons why homeowners should prioritize foundation waterproofing:

  • Structural Integrity: Water damage can weaken the foundation, leading to cracks, bowing walls, and even foundation failure.
  • Health Concerns: Damp environments are breeding grounds for mould and mildew, posing health risks to occupants.
  • Property Value: A well-maintained, waterproofed foundation enhances the value of your property.
  • Cost Savings: Proactively addressing water issues can prevent more costly repairs down the line.

Waterproofing Methods

There are several waterproofing techniques, each suited to different scenarios and foundation types. Here’s an overview of the most effective methods:

Exterior Waterproofing

Exterior waterproofing stops water from entering the foundation walls, making it a comprehensive solution for moisture control. The process typically involves excavating around the foundation, applying a waterproof membrane, and installing drainage systems like a French drain or weeping tiles to redirect water away from the foundation. Although labour-intensive and costly, exterior waterproofing offers a long-term solution for moisture control.


Interior Waterproofing

Interior waterproofing methods address water ingress from inside the basement. These include sealants, interior weeping tile systems, and sump pumps. While less disruptive than exterior waterproofing, interior solutions often manage water ingress rather than preventing it outright. They’re best used in conjunction with exterior waterproofing methods for a comprehensive solution.

Drainage Solutions

Proper drainage is critical to foundation waterproofing. Ensuring that water flows away from your foundation prevents hydrostatic pressure and mitigates the risk of water damage. Solutions include regrading the landscape, installing or repairing gutters and downspouts, and incorporating advanced drainage systems to manage surface and subsurface water effectively.

Concrete Work

Cracks and gaps in the foundation can be entry points for water. Repairing these defects with hydraulic cement, epoxy injections, and basement concrete flooring is all vital for maintaining a dry basement. These repairs, while seemingly minor, play a significant role in the overall waterproofing strategy.

Choosing the Right Waterproofing Company

Selecting a reputable waterproofing company is crucial for ensuring the job is done correctly and efficiently. Here are factors to consider when choosing a partner for your waterproofing needs:

  • Experience and Expertise: Look for companies with a proven track record in foundation waterproofing, especially those familiar with the unique challenges of Southern Ontario’s climate.
  • Comprehensive Services: A company offering a range of services, from basement lowering and underpinning to exterior waterproofing and concrete works, can provide a more holistic approach to your waterproofing needs.
  • Quality Materials: The effectiveness of waterproofing measures depends significantly on the quality of materials used. Ensure the company uses high-grade waterproofing membranes, sealants, and drainage systems.
  • Warranties and Guarantees: A trustworthy company stands behind their work with strong warranties and satisfaction guarantees, offering peace of mind to homeowners.
  • Customer Reviews and Testimonials: Feedback from previous clients can offer insights into the company’s reliability, quality of work, and customer service.


Maintaining Your Foundation Post-Waterproofing

Waterproofing your foundation is a significant investment in your home’s future. To protect this investment, regular maintenance is essential. This includes:

  • Periodically inspecting the exterior and interior of your foundation for signs of moisture or damage.
  • Keeping gutters clean and ensuring downspouts direct water away from the foundation.
  • Monitoring the performance of sump pumps and other drainage systems to ensure they operate efficiently.
  • Being vigilant about landscape changes that could affect the flow of water around your foundation.

Final Thoughts

Foundation waterproofing is a critical aspect of home maintenance that should not be overlooked. By understanding the causes of water damage, familiarizing yourself with waterproofing methods, and selecting a competent waterproofing company, homeowners can ensure their property remains dry, healthy, and structurally sound.
