Basement Waterproofing

The foundation is the most important part of your house. Your basement walls provide a solid base for the structures above them in your home or building. When a basement or foundation wall begins to bow or crack it can jeopardize the structural integrity of your home. A damp wet basement can also lead to mold growth that can cause serious health issues and reduce the value and desirability of your home.

Safeguard your family’s health, your most valuable possessions and your property’s value. Healthy homes start with dry basements!

Depending on the location, type and severity of your basement leak there are a number of different methods that could be deployed to waterproof your basement.

The best option to secure your basement from leaks is exterior foundation waterproofing.

Exterior foundation waterproofing consists of:

  1. Covering the walls with a Platon membrane which creates an impermeable vapour and air gap barrier, blocking moisture while allowing concrete to breathe (click here to view the platon installation guide)

  2. A working weeping tile system is imperative with all foundation waterproofing systems

  3. Covering the weeping tile with a proper amount of clear drainage stone

  4. Window wells and drains in window wells where applicable

  5. Proper grading away from foundation
