Interior Waterproofing

Don't let water damage threaten your Toronto home – trust Royal Waterproofing to create a dry, secure basement for lasting peace of mind.

Why Do Toronto Basements Leak?

Toronto homeowners know the frustration of basement leaks all too well. Here’s why our city’s basements are particularly vulnerable:

  • Heavy Clay Soil: Much of Toronto sits on dense clay soil. When this soil gets saturated, it puts immense pressure on your foundation (hydrostatic pressure), forcing water to find its way in.

  • Aging Infrastructure: Many Toronto homes have older foundations more likely to have cracks, worn seals, and areas where water can penetrate.

  • Extreme Weather: Toronto’s freeze-thaw cycles wreak havoc on foundations. Water seeps into tiny cracks, freezes and expands, widening those cracks over time. Heavy downpours and rapid snowmelt also overwhelm drainage systems.

  • Hidden Issues: Sometimes leaks aren’t caused by the foundation itself. Clogged gutters, faulty window wells, or improper grading around your home can direct water towards your basement.

Common Signs of Trouble:

  • Visible water intrusion: This could be puddles, trickling water, or just persistent dampness.

  • Water stains and efflorescence: Discoloration on basement walls or a white, powdery substance (efflorescence) indicates moisture problems.

  • Musty odors: That damp basement smell is a sign of mold or mildew growth.

  • Foundation cracks: Even hairline cracks can be entry points for water.

The Benefits of Interior Waterproofing

Investing in interior waterproofing isn’t just about fixing a leaky basement, it’s about protecting your home and your family’s well-being. Here’s why it’s a smart decision:

  • Prevent Costly Repairs: Water damage doesn’t fix itself. A small leak today could become a major structural issue, mold infestation, or even a flooded basement tomorrow. Interior waterproofing is a proactive investment that saves you money and headaches in the long run.

  • Protect Your Investment: Your home is likely your biggest asset. A dry, healthy basement is essential for maintaining its value – and for attracting buyers if you ever decide to sell. Buyers are wary of homes with moisture problems, and for good reason!

  • Healthier Living Space: Damp basements are breeding grounds for mold and mildew. These allergens can trigger respiratory problems, especially in children, seniors, or those with sensitivities. Interior waterproofing protects your family’s health by creating a dry, mold-free environment.

  • Enhanced Comfort and Usability: Forget that cold, damp, musty basement feeling! A properly waterproofed basement can be finished and transformed into extra living space – a home office, playroom, gym, or guest suite. The possibilities are endless.

  • Peace of Mind: Knowing your basement is protected from water damage gives you peace of mind, especially with Toronto’s unpredictable weather!

Royal Waterproofing's Interior Solutions

Royal Waterproofing understands that no two basement leaks are the same. That’s why we take a tailored approach to solving your waterproofing problems. Here’s an overview of our interior solutions:

  • Interior Drain Systems: These strategically installed systems are designed to intercept water before it reaches your basement floor. Water is collected in perforated pipes laid around the perimeter of your basement and directed to a sump pump or floor drain.

  • If used the sump pump then safely expels the water away from your foundation. Interior drain systems are highly effective in managing chronic leaks and hydrostatic pressure.

  • Crack Injections: Foundation cracks are a common entry point for water. We use specialized injections to permanently seal these cracks from the inside.

    • Epoxy injections: Ideal for repairing structural cracks and restoring a foundation’s strength
    • Polyurethane injections: These flexible injections are excellent for sealing active leaks, expanding to fill the void and stop water in its tracks.

  • Waterproof Membranes: These advanced coatings are applied directly to basement walls, creating a powerful barrier against moisture penetration. They’re particularly useful for dampness or persistent seepage through porous concrete. Our team will recommend the best membrane for your specific needs.

We thought that your men who worked on our house were professionals; hard-working, skilled, thorough, obviously proud of their workmanship, personally courteous and respectful of our house and privacy.

They did an excellent job in cleaning up at the end of each day and at the contracts completion.

Royal's work crew was courteous, professional and efficient. Not only were they managed by a foreman, but Bill himself regularly attended at my house to personally supervise the work and ensure that the work proceeded smoothly.

I am an extremely happy customer of Royal Waterproofing, and I would not hesitate whatsoever in recommending them to anyone who needs waterproofing work done.

I am pleased to recommend the services of Royal Waterproofing. The damp smell we had in our basement due to moisture seeping in is no longer evident. Bill and his team were very professional in their dealings with us before, during and after the work was done. Details and expectations were clearly explained. They were all a pleasure to deal with.
