What Is Exterior Waterproofing?
Exterior waterproofing, also known as foundation waterproofing, is a method of home waterproofing that prevents water from entering your basement walls from the outside. By digging down to the foundation, we can install exterior drains and apply waterproof membranes to the entire exterior of your property.
Not only do the membranes prevent water from touching your home, but the addition of exterior drains also helps collect and channel water away from your foundation, preventing the buildup of hydrostatic pressure, which can cause foundation cracks over time.
Benefits Of Waterproofing Your Basement From The Outside
- Increased Property Value: A waterproofed basement can increase a home’s value by up to 10%, alternatively, a wet basement can cause a home to lose up to 25% of its value, with home improvement data showing that waterproofing can yield an ROI of about 30%!
- Protection From Flash Floods: A single flash flood event on July 15-16, 2024, caused over $940 million in insured damage across Toronto and southern Ontario, according to the Insurance Bureau of Canada (IBC).
- Prevent Foundation Cracks: The presence of heavy clay soil, common in the GTA, expands when it gets wet and shrinks as it dries, exerting immense hydrostatic pressure on a home’s foundation walls.
- Protect Foundation Integrity: By creating a barrier that prevents water from reaching the foundation, you mitigate the effects of freeze-thaw cycles and prevent the formation of foundation cracks.
- Dry Basement All Year Round: A dry basement is a healthy basement. By preventing water intrusion and managing moisture, exterior waterproofing eliminates the damp, dark environment where mold and mildew thrive.

Exterior and Foundation Waterproofing FAQs
How do you waterproof a basement from the outside?
Exterior waterproofing is a comprehensive process that involves several key steps to ensure your home remains protected against water intrusion. First, our experts conduct a thorough assessment of your property, identifying vulnerable areas such as foundation cracks or areas prone to water seepage. Next, we excavate around the foundation to create space for waterproofing materials. We then apply a high-quality waterproof membrane, followed by improving soil grading and drainage systems to channel water away from your home effectively. Finally, we backfill the excavated area, ensuring proper compaction to prevent future water pooling.
How much does it cost to externally waterproof your basement?
Our Exterior Waterproofing prices start at $50 – $300+ per linear ft. However, please note that all prices are approximate and may vary based on the depth, access and other specifics of a project. Please get in touch with us today for a Quote!
How long does foundation waterproofing last?
The longevity of exterior waterproofing largely depends on the quality of materials used, the effectiveness of the installation, and environmental factors. Generally, a professionally installed exterior waterproofing system can last up to 25 years or more, providing long-term protection against water damage and preserving the structural integrity of your home.
Can I waterproof the outside of my basement myself? Or should I hire a professional waterproofing company?
While DIY waterproofing kits are available, we highly recommend hiring a professional for exterior waterproofing due to the complexity and importance of the process. Certified professionals have the expertise, access to high-quality materials, and the necessary equipment to ensure effective and lasting waterproofing. Attempting to do it yourself may lead to subpar results and potential future issues.
What are the signs of external basement leaks?
Several signs indicate the need for exterior waterproofing:
- Water stains or discoloration on basement walls.
- Cracks in the foundation or basement walls.
- Damp or musty odors in the basement.
- Gaps or deterioration in caulking or sealants around windows and doors.
- Water pooling near the foundation after rainfall.
