Benefits of Interior Basement Waterproofing
here’s more to interior waterproofing than just fixing leaks. It plays a major role in mould prevention, helps preserve your home’s structure, and even increases your property value. If you’re thinking about converting your basement into a living area, proper waterproofing lays the groundwork for a safe, livable space.
Toronto homeowners often face limited access to exterior walls, especially in older neighbourhoods or tightly packed lots. That’s where interior waterproofing really shines. It allows us to install a complete basement drainage system from inside the home with minimal disruption and maximum impact.
Types of Basement Waterproofing Services We Offer in Toronto
At GAMCON, we provide a comprehensive range of foundation waterproofing and basement moisture control services across Toronto and surrounding areas. Whether you’re addressing an immediate concern or planning preventative upgrades, our team offers the right solutions for your needs.
In-Home Assessment & Moisture Mapping
Our interior waterproofing methods are ideal for addressing existing water issues from the inside. This service includes the installation of internal drainage systems, sump pumps, and vapour barriers. These measures work together to stop basement leaks and manage water effectively, even during the wettest seasons.
Interior Trench & Drainage System Installation
GAMCON’s exterior waterproofing approach involves excavation around the foundation, application of foundation coatings, and the installation of exterior drainage systems. These solutions are designed to prevent water from ever entering your basement, offering the most comprehensive foundation waterproofing option for long-term protection.
Wall Vapour Barrier & Moisture Sealing
We address foundation cracks and vulnerable areas before they lead to serious water damage. Our services include epoxy injections, polyurethane sealing, and membrane applications, along with routine maintenance to ensure your basement remains dry year-round.
Sump Pump & Backwater Valve Setup
No interior waterproofing system is complete without a high-efficiency sump pump. We’ll install one that fits your needs, along with a battery backup system to keep things running during power outages. We also include a backwater valve to protect against sewage backup. Many Toronto homeowners qualify for the City of Toronto flood protection rebates, and we’re happy to guide you through the process.
Crack Injection & Foundation Sealing
Cracks in your basement walls? No problem. We use epoxy injection or polyurethane crack sealing, depending on the situation, to stop water from coming through. In cases where extra strength is needed, carbon fibre reinforcement may be used to stabilize and protect your foundation.
Floor Re-Pouring & Clean Finish
After all the waterproofing components are installed, we restore your basement floor with a fresh concrete floor re-pour. The result is a smooth, clean finish that’s ready for flooring, framing, or simply a more polished space. We take great care to keep your home tidy from start to finish.

Interior vs. Exterior Basement Waterproofing
Both interior and exterior basement waterproofing methods have their benefits, but choosing the right one depends on your home’s layout and accessibility. Exterior waterproofing stops water before it gets to your walls, but it often involves excavation, heavy equipment, and higher costs.
Interior waterproofing, on the other hand, is far less invasive and typically more affordable. It focuses on managing water once it’s entered the structure, using components like vapour barriers, interior drainage channels, and sump pump installation to keep your basement dry. If you’re in a tight urban lot or don’t want to disturb your landscaping, interior solutions are often the best fit.

Testimonials
Janice & Rob
The Beaches (Toronto)
“Our basement was a damp nightmare – moldy, leaks everywhere. We had other companies look at it, but GAMCON was the only one who truly understood the problem. They used this heavy-duty membrane stuff…it’s overkill, honestly, but in the best way! Now our basement’s completely dry, and we even finished it. Feels like a whole new part of our home.”
Sarah T
Etobicoke
“We bought an older home in Etobicoke with a partially finished basement. We were nervous about hidden water issues. GAMCON’s inspection was SO thorough, and they found some old cracks that needed fixing. The best part? They explained everything in plain language, and their waterproofing materials were top-notch. Now we sleep easy knowing our basement is protected.”
Costa and Maria P
Greektown (Toronto)
“We run a family restaurant on the Danforth, and it’s been in this building for generations. A few years ago, we noticed water seeping in – a disaster waiting to happen. GAMCON found some foundation issues we didn’t even know about. They used these crazy strong injections and fixed it right. Their work is solid – just like the materials they use – and we know our business is safe.”
Steve M
Property Manager, North York
“Our office building in North York had a leaky basement that was affecting storage. GAMCON came highly recommended for getting the job done fast and right. Not only did they use the best waterproofing stuff we’ve seen, but their crew was super efficient. Minimal mess, and now those leaks are a distant memory.”
