Polyaspartic Coatings for Elevator Pits

Elevator pit repair and waterproofing at a private residence located on O’Connor Dr. in Toronto was one of the projects done in October. This particular elevator shaft houses a piston-operated elevator which requires specialized attention to ensure effective waterproofing around the piston housing.

Repair Method

Substrate Preparation

Our repair process begins with meticulous surface preparation, which includes thorough cleaning and addressing any cracks that may be present in the pit's structure. It's crucial to create a solid foundation for the waterproofing process. For crack repair, we open up any existing cracks using chipping techniques and subsequently treat them with an industrial-strength adhesive, followed by the application of a specialized crack filler material.

Cold Joint Waterproofing

One of the critical areas to waterproof in an elevator pit is the cold joints, where the floor slab meets the walls. These junctures are often vulnerable to water leakage due to their inherent structural weaknesses. To reinforce these cold joints and make them impervious to water, we employ a proven approach. Chipping is done to clean out the joints, and a continuous patch is applied along the entire joint at a 45-degree angle. Following this, a waterproofing material is layered over the cold joints to enhance their water resistance.

Waterproofing Membrane Application

The last step of our waterproofing process involves the application of a polyaspartic waterproofing membrane. This high-performance coating is spread across the entire floor of the elevator pit and is extended onto a portion of the walls, effectively sealing the entire area, including the previously reinforced cold joints. The use of polyaspartic coatings is a game-changer, as they offer numerous benefits, such as rapid curing, excellent adhesion, and exceptional resistance to wear and tear, ensuring long-lasting and reliable waterproofing results.

The application of polyaspartic coatings not only enhances the durability and longevity of the waterproofing but also provides additional advantages, including enhanced chemical resistance and UV stability. Furthermore, polyaspartic coatings cure quickly, minimizing downtime for elevator pit repairs and ensuring a fast return to operational status. With our commitment to quality and cutting-edge solutions, we take pride in delivering top-tier waterproofing results for elevator pits, safeguarding them against water intrusion and the associated structural damage.
