Interior or internal waterproofing is the process of repairing leaks from inside the property and is an effective solution to a damp basement. When your basement is moist, it leads to mold and mildew, resulting in foul odors and unhealthy bacteria on your property. Hence interior waterproofing is essential, as it helps decrease the basement moisture and avoids problems. This waterproofing solution also deals with hydrostatic pressure, which causes wet basements.

Internal waterproofing is beneficial because of these three reasons:


Internal waterproofing effectively repairs leaks of a property from the inside when there is limited space to handle the problem from the outside.

The wet basement is caused by hydrostatic pressure, which implies the groundwater level beneath the concrete slab fluctuates and seeps through the basement wall. This groundwater signifies there may be an underground watercourse near the building.



An internal waterproofing system is an affordable option for unfinished living areas.

Exterior or external waterproofing is the process of exposing the building foundation, applying suitable waterproofing material to the exterior, and preventing the groundwater from getting into the foundation walls. This is the most common method for repairing basement foundations and providing waterproofing solutions for damp basements in Toronto. Here are the steps involved in the exterior waterproofing process:

Exterior waterproofing

Excavate around the building perimeter: Although the size of the excavation depends on the elevation of your property, most pits are generally four to eight feet deep and two to twelve feet broad.

Installing Speed Shoring

Speed Shoring installation: This is essential for preventing dirt from refilling the excavated pit and ensuring the safety of workers.

Foundation Wall Cleaning

Replace old weeping tiles: Once footing is reached through excavation, the old weeping tiles are replaced with new four-inch weeping tiles.

Foundation Wall Cleaning

Clean and Inspect the foundation wall: There may be voids or structural fractures in the foundation walls. Hence they are cleaned and speculated to identify such issues. Non-shrink specialty cement is used to mend the chiseled-out sections.

Trowel-On Rubber Membrane Application

Installation of a rubber membrane: This is crucial for the external waterproofing of a property. It is designed in a way that will allow expansion in case of foundation movement in the future.

Installation rubber waterproofing

Mesh installation on the membrane: The final rubber layer of waterproofing supports and strengthens the initial rubber layer.

A solid side drainage sheet is attached to the termination bar: Commercial drainage functions as a drainage membrane and a protective layer which is better than the residential grade dimple board.

Install window wells: You can call us if your property has windows below grade and requires the installation of window wells. A weeping tile measuring four inches is laid vertically, extending from the window to the footings. The weeping tile and pipe mustn’t contact; otherwise, it will lead to clogging.

Use a 3/4-inch layer of clear gravel to cover the weeping tile: This is important for increasing the amount of drainage. When the gravel layer and soil are combined, it decreases water absorption through the weeping tiles and avoids drain blockage.

Cover the weeping tile

Refill the soil and restore the ground to the original level: Once the soil is refilled, the foundation is wholly waterproofed to avoid water penetration and solve the problem of a damp basement.
