about us

Since 2015, Joint Seal Waterproofing has been providing elevator pit waterproofing in Toronto, the GTA and the surrounding areas. Our waterproofing applications are designed to withstand the harsh elevator shaft environment, and protect surfaces against oils and chemicals, ensuring long-lasting results.

We specialize in concrete shaft 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 Latest Tech

IN MEMBRANE APPLICATIONS

We use top-of-the line equipment and specialized materials, to offer you the best solution in protecting expensive, sensitive elevator equipment. 

We make quick and durable applications possible, which is essential in reducing the total cost of pit waterproofing - closing off an elevator shaft during repairs carries a high price tag.

Annual Maintenance

Pit cleaning is included in our regular maintenance routine.

Repairs & Waterpfoofing

Shaft cleaning is done in support of repairs.

Sump Pump Performance

Pit cleaning improves the efficiency of sump pumps.

Elevator Pit

CLEANING

Part of maintenance or repairs

Elevator equipment and sump pumps can work efficiently.

Cleaning can reveal the true condition of the shaft.

Hidden issues

Concrete deterioration is made evident.

Large cracks can be detected.

Flooding levels and the extent of damage can be determined.

EARLY

WARNING SIGNS

Saturated surfaces and rusted elevator equipment warn about an imminent problem.

The elevator shaft can start leaking at any time, leading to elevator equipment damage and eventual shutdown.

Damp Walls

The darker wall surface at the bottom of the pit can indicate previous flooding that reached that level and/or wall deterioration due to water saturation.

Calcium Deposits

Caused by a significant flow of water seeping from the outside through larger wall cracks. Elevator equipment will be damaged if no repairs are done.

Rusted Metal

Indicates flood level, possible wall saturation, and damage to elevator equipment. The shaft can start leaking at any time, causing further damage.

Thermographers

Our highly-trained professionals will provide the true diagnosis upon inspection.

Interpreting an
Infrared Scan

Infrared imaging and temperature readings indicate the exact level of water saturation.

Cost-Efficient
Applications

Repair type will be determined based on crack size and general pit condition.

THE BEST SOLUTION

ENGINEERING SOLUTIONS

Once an infrared scan is done, precise solutions can be engineered to ensure efficient repair and waterproofing.

OPTIMAL REPAIR METHODS

One of the following repair methods is applied when a pit needs waterproofing:

Floor/wall corner

Efficiently waterproofed with a triplex application.

Piston housing waterproofing

Waterproofed through liquid rubber injection.

Crack repair on wall and/or floor surfaces

Crack repair helps in preventing elevator shaft flooding.

Block wall waterproofing

Includes drainage system installation and rubber fiberglass membrane.

A PRECISE DIAGNOSIS

An infrared camera makes any leakage evident.

The darker the colour and the lower the temperature, the greater the water saturation problem.
Precise solutions can be engineered to ensure efficient repair and waterproofing.
