Waterproofing Services?

When your home experiences indoor flooding during rainfalls or snowmelt, it's a clear signal to consider house waterproofing. Homes succumb to floods and leaks for various reasons: cracks in the foundation, high groundwater levels, improper grading, clogged gutters, or flawed installation. 


A prevalent cause of basement water infiltration is the uneven compression of soil that loosens after the house is built. This condition makes it easier for water to seep through and accumulate, resulting in a damp, musty basement. 


Over time, this moisture absorption can compromise the structural integrity of your primary walls, posing a significant risk to your home's stability and comfort.

Process of Exterior Foundation Waterproofing

Exterior or external waterproofing addresses a leaky basement by working from the outside. It involves digging up the soil around your property to reveal the foundation, followed by the application of waterproofing materials. This establishes a waterproofing system designed to divert and distribute water away from the foundation walls, effectively preventing moisture penetration.


MMT Waterproofing Inc. has a unique way of applying six different layers of waterproofing materials. This is one of the best waterproofing solutions used to fix basement leaks and the most common way to do a basement foundation repair.

Benefits of External Waterproofing:

  • Protection from damp, mildew, and mould. Dampness and mildew produce unpleasant smells, and external waterproofing eliminates sources of musty odours and allergens within your home. 
  • Restores your basement and home, as well as protects your personal belongings. 
  • Prevents deterioration of foundation walls and enhances structural integrity.
  • Raises the value of the home.
