Elevator Pit Cleaning – the First Step!
We offer elevator pit cleaning as part of your annual maintenance, or in support of work done in the pit. As a complementary service to our clients, we offer
an infrared survey of the pit condition.

Elevator Pit Cleaning

Whether done as part of regular maintenance or repairs, pit cleanin can help with pit diagnosis.

1. Can reveal issues with dampness, calcium accumulation, and rusted metal equipment.

2. Any of these issues point to a greater problem - a leaking elevator pit.

Pit Cleaning

Pit Cleaning

As part of maintenance or repairs,

can reveal issues.

Damp Walls

The darker wall surface at the bottom of the pit can indicate leakage.

Calcium around Cracks

Calcium deposits on the elevator shaft walls indicate a much larger slab crack.

Rusted Metal

Rusted metal shows previous flooding levels.


For over six years, Joint Seal Waterproofing, has been providing elevator pit waterproofing in Toronto, the GTA and the surrounding areas. We specialize in pit concrete repair, restoration, and crack injection.


High-strength concrete adhesives allow us to perform all concrete repairs from inside the shaft, ensuring long-lasting results. The use of a polyurea-based waterproofing membrane restores water impermeability of the shaft wall.

We offer elevator pit cleaning as part of your annual elevator pit maintenance, and as part of our waterproofing process. A clean elevator pit prolongs the life of sump pumps, increasing the efficiency of drains, and reduces the corrosion of the elevator mechanism.
