Waterproofing Elevator Pits

Joint Seal Waterproofing is a Toronto-based company, specializing in elevator pit waterproofing and repair. Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.

Our Elevator Shaft Waterproofing Services

For over five years, we have been providing elevator pit waterproofing in Toronto and the GTA. We specialize in elevator shaft concrete repair, restoration, and crack injection. High-strength concrete adhesives allow us to perform all concrete repairs from the inside of the shaft, ensuring long-lasting results. Use of crystalline coating restores water impermeability of the shaft wall.

Elevator Pit Cleaning

Even though nobody sees the trash that accumulates on the elevator pit floor, it can contribute to a serious problem. To make matters worse, if the pit has not been waterproofed and is leaking, the accumulated water will interact with the garbage, which can produce a chemical reaction. As the amount of trash grows, it will also interfere with the mechanics of the elevator system.

There is a way to avoid such issues - we offer elevator pit cleaning as part of annual maintenance, or as part of our waterproofing process. Elevator shaft cleaning prolongs the life of sump pumps, increasing the efficiency of drains.

Infrared Diagnostics

As a complementary service to our clients, we offer infrared surveys of the elevator pit. This exclusive thermographic scanning service is of commercial-grade quality. The infrared cameras identify leaks that are not obvious to the naked eye. The exact level of water saturation is shown through images and temperature readings.

Our waterproofing solution experts rely on years of field experience, supported by high-end scanning equipment. They will suggest the precise solution (if any) a given elevator pit needs - when elevator shaft walls are cracked, repairs are not always needed. It depends on the size of the crack and the condition of the surrounding area.

We always provide a detailed inspection summary report, supported by infrared scans, presenting a more in-depth view of proposed repairs.

Waterproofing Elevator Pits

Depending on the condition of the shaft and its characteristics, different procedures are followed to ensure long-term elevator pit waterproofing:

  • floor/wall corner repairs and waterproofing
  • floor/wall crack repair and patching
  • piston housing waterproofing
  • block wall waterproofing

Please refer to the Repair Methods section below for more details.

Efficient Elevator Pit Waterproofing for Great Results

No matter how severe the leaking, we can help. Long-lasting elevator shaft waterproofing is made possible through specialized applications and high-end waterproofing materials.

Repair Methods

waterproofing & repair methods

Floor/Wall Corner

Most of the elevator pit waterproofing is done for wall/floor corners (cold joints) – a weaker area in a concrete surface, where most leaking occurs. A multi-layer waterproofing repair method is applied to ensure long-term waterproofing: concrete adhesive, patching, primer, fiberglass, and basalt.

Wall/Floor Crack Repair

When elevator shaft waterproofing is required due to cracks on elevator shaft walls or floors, the cracks are first prepped and then filled with specialized elevator pit waterproofing materials: adhesive, polymer cement, and primer. For all patches of less than a ¼ inch thick, polymer cement is used.

Block Wall Waterproofing

Waterproofing elevator shafts made of block walls requires a special procedure. First, to make sure no water accumulates inside the block wall, drainage is installed at the bottom. Next, appropriate waterproofing materials are applied. Some repairs include application of crystalline, such as Xypex or Hydroseal.

Piston Housing Waterproofing

For piston-operated elevators, a specialized procedure is followed to ensure long-lasting elevator pit waterproofing. Any accumulated liquid is pumped out of the housing around the cylinder/piston assembly, the void is cleaned and injected with a soft rubber.
