Interior Basement Waterproofing in Toronto

Keep Water Out. Protect What Matters.

Is your basement showing signs of moisture, musty odours, or foundation leaks? At UPR, we offer effective and affordable interior waterproofing solutions for homes across Toronto and the GTA. Whether you’re seeing early signs of trouble or need emergency protection, our system keeps your basement dry — from the inside out.

 Why Interior Waterproofing?

Interior waterproofing is a non-invasive method that manages water after it enters the foundation wall — directing it safely to a sump pump and out of your home. It’s ideal for:

  • Leaking foundation walls

  • Wet basement floors

  • Cracks letting in water

  • Musty smells or visible mold

  • Homes where exterior waterproofing isn’t possible

It’s a smart, cost-effective option — especially in finished or semi-finished basements.

 What’s Included in Interior Waterproofing

We customize every system to fit your basement and water problem:

  • Trench along interior perimeter
    We carefully open the floor along walls to install a drainage system.

  • Weeping tile (drain pipe) installation
    Redirects water to your sump pump system for safe discharge.

  • Wall membrane application
    A vapor barrier channels moisture from foundation walls into the drainage system.

  • Sump pump & battery backup (if needed)
    Automatically removes water — even during power outages.

  • Crack sealing & mold remediation
    Repair visible wall cracks and remove mold-affected materials when necessary.
