Ensuring Lasting Waterproofing Results for Elevator Pits

Tenera was approached to provide application design specifications to ensure lasting waterproofing results for an elevator pit in a low-rise commercial building on Bloor St. To achieve durable and effective waterproofing, we had the contractor implement a specialised multi-step repair method tailored to address the unique challenges of elevator pit environment.

Cleaning and Surface Preparation

The first step involved thoroughly cleaning the elevator pit to ensure no leaks were overlooked. The contractor then did chipping to open up any cracks sufficiently, allowing for crack repair materials to be installed properly. 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 in this case), were meticulously waterproofed around the entire pit. This step was crucial, as most leaking tends to 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

ApplicationThe final step indicated in our application 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 that is essential for maintaining the integrity of the elevator pit.

Benefits of Polyaspartic Coatings for Elevator Pit Waterproofing

Polyaspartic coatings offer several key benefits for elevator pit waterproofing. They provide exceptional resistance to abrasion, chemicals, and temperature fluctuations, ensuring the coated surfaces remain durable and effective over time. The quick curing time of polyaspartic coatings allows for faster project completion, minimising elevator lockout time. Additionally, their superior adhesion and flexibility help accommodate structural movements and vibrations, which are common in elevator pits. Overall, polyaspartic coatings deliver a reliable and long-lasting solution for waterproofing elevator pits, protecting them from potential water damage and extending their service life.
