Repair Specifications for Elevator Pit Waterproofing

Tenera was hired to provide a comprehensive waterproofing solution for an elevator pit in a commercial building on Main St. W in Hamilton, ON. This project required specialised expertise and ensuring adherence to our repair protocols to ensure long-lasting results. The contractor was instructed to follow our repair specifications.

Repair Method

The initial phase involved thorough surface preparation of the elevator pit. All contaminants and debris were removed to ensure a clean substrate. Visible cracks were then filled to create a smooth and even surface. Following this, the contractor addressed the cold joints—the inherent weak points where the concrete walls meet the floor and the wall corners. These areas were reinforced by installing a continuous patch at a 45-degree angle along the floor-wall joint, which was subsequently coated with a high-performance waterproofing material. This coating was extended to cover portions of both the floor and the wall surrounding the joint, ensuring a robust and continuous seal.

Polyaspartic Coating and Its Advantages

The final step in the waterproofing process involved the application of a polyaspartic coating, enhanced with a color pigment. Polyaspartic coatings offer several significant advantages: they cure rapidly, which allows for faster project completion and minimal downtime; they exhibit superior durability, providing excellent resistance to abrasion, chemicals, and UV exposure; they maintain high flexibility, accommodating slight movements in the substrate without cracking or peeling. Where aesthetics matters more, they enhance the treated area with a visually appealing finish.

By having the contractor employ this multi-layered approach, we ensured that the elevator pit was comprehensively sealed, providing durable and reliable waterproofing results that will withstand the test of time.
