When Tenera was hired to provide specifications for the waterproofing of six elevator pits in two mid-rise residential buildings located on Grandview Way in North York, the project was carried out in four stages to ensure tenants would have access to an elevator at all times. The client sought durable and effective waterproofing solutions, and Tenera delivered specialised multi-step repair methods tailored to the unique challenges of the elevator pit environment.
Cleaning and Surface Preparation
The initial step involved thoroughly cleaning the elevator pits to identify any potential leaks. The contractor then performed chipping to open up cracks sufficiently, allowing for the proper installation of crack repair materials. Once all leaks were identified and stopped, parging was applied to create an even surface, ensuring a more durable and reliable repair.
Cold Joint Waterproofing
Cold joints, which are weak areas where two concrete slabs meet (such as the wall and floor), were meticulously waterproofed around the entire pit. This step was crucial, as leaks often occur in these areas. To fully seal the cold joints, a continuous patch was installed at a 45-degree angle along the joints, providing a robust barrier against water ingress.
Polyaspartic Coating Application
The final step in our design was the application of a polyaspartic coating, which included a color pigment for aesthetic purposes. This coating was applied to both the floor and part of the walls (an upturn), ensuring comprehensive coverage. Polyaspartic coating fully seals any surface it is applied to, offering a long-lasting protective layer essential for maintaining the integrity of the elevator pit.
