What Is Exterior Waterproofing?

Exterior waterproofing is a set of works necessary to protect the outer part of the house from water damage. This can be achieved by creating a barrier that separates the exterior walls of the building from water, preventing it from entering the structure. Water penetration through the exterior walls of the house will inevitably lead to the growth of mold and mildew, as well as damage to the structure, resulting in costly repairs.

Exterior Waterproofing Process

The Quality Age Build team takes a step-by-step approach to exterior foundation waterproofing Toronto, discussing all the nuances with the client at each stage.


Before installing external waterproofing, we excavate the soil around the foundation down to the slabs. Excavation in Toronto allows us to identify the root problem and immediately begin addressing it.

Wall Cleaning

Specialists prepare the wall surface by removing dust and dirt. Typically, this is done mechanically, and gaps and cracks are filled with hydraulic cement.

Delta Membrane Installation

Next, we install delta waterproofing membranes, which create a barrier between the wall and any type of liquid that may come into contact with it.

Drainage System Installation

We install a drainage system to increase protection from water and basement insulation. This includes perforated pipes lined with gravel, which filter debris. The system directs water away from the foundation walls to prevent it from seeping into the space.


The final step is backfilling. We fill any voids created by soil excavation with special material. Afterward, we compact and stabilize the soil to prevent shifting over time.

What are the reasons you might require exterior waterproofing?

Foundation Leaks

Water entering the foundation can render a space uninhabitable, as dampness and moisture can cause damage to both property and human health. Mold and mildew are not only aesthetic problems but also pose a risk of respiratory illnesses.

Poor Drainage

The wear and tear of the drainage system also negatively impacts the condition of the foundation and walls over time, as infiltrating moisture possesses destructive power, undermining the “health” and integrity of your home.

Cracks in Foundation Walls

Emergency situations require immediate attention. To save on repair costs, it is important to address wall cracks as soon as possible rather than postponing repairs indefinitely.
