Waterproofing
We use specialized techniques to repair cracks and seal joints in elevator pits, creating a strong, seamless bond that stays in place and won’t peel over time. Our materials are designed to hold even under high pressure, ensuring long-lasting results.
To further protect the area, we apply durable, waterproof coatings. These coatings cure almost instantly, allowing a one-car elevator to be back in service as quickly as the next day.
Infrared Diagnostics
We provide a professional infrared scanning service to accurately assess the condition of elevator pits. This advanced technology helps us pinpoint potential issues with precision.
Our clients benefit from top-tier equipment and the expertise of our experienced team. After every inspection, we provide a detailed report that clearly explains the findings and supports the recommended repairs.
Elevator Pit Cleaning
Available as part of regular maintenance or alongside repairs, our elevator pit cleaning service helps improve the performance of sump pump drains.
To give our clients extra value, we also provide an infrared scan of the pit’s condition as part of this service.
WATERPROOFING
Floor / Wall Corner
Our repair process uses a multi-layer approach for durability and effectiveness. It includes applying an adhesive, patching material, primer, fiberglass reinforcement, and a polyurea-based waterproof coating.
Floor / Wall Cracks
To repair cracks, we carefully widen them with a saw, fill them with adhesive, and patch them with cement. The area is then waterproofed with a primer to ensure long-lasting protection.
For smaller patches less than 1/4 inch thick, we use a specialized polymer cement for added durability.
Piston Housing
We remove any water that has collected around the piston, clean the area thoroughly, and seal the space by injecting it with a durable liquid rubber material.
Block Walls
We install a drainage system and apply high-quality waterproofing materials to ensure long-lasting protection.
INFRARED TECH
Elevator Waterproofing Thermographers
Our skilled elevator waterproofing specialists use advanced infrared scanning technology to identify problem areas and recommend the best waterproofing solutions.
Thermal scans provide a clear picture of any issues, and we present precise recommendations in a detailed proposal for your approval.
To ensure lasting results, we use top-quality waterproofing spray and concrete adhesives to repair and waterproof common elevator pit surfaces.
Interpreting an Infrared Scan
Infrared cameras reveal everything—nothing stays hidden!
In the images below, darker areas combined with lower temperatures indicate where water has accumulated.
The darker the color and the cooler the temperature, the more severe the water saturation issue.
PIT CLEANING
Elevator Pit Cleaning
Pit cleaning, whether as part of routine maintenance or repair work, helps uncover potential issues:
-
It can reveal signs of dampness, calcium buildup, or rusted metal equipment.
-
These signs often indicate a larger issue, such as a leaking elevator pit.
Damp Walls
A darker wall surface at the bottom of the pit can indicate one of two things:
-
There was previous flooding that reached that level, but the water was drained out using a sump pump.
-
The wall has absorbed water and remains damp. This could lead to leaks and potential damage to elevator equipment if not addressed.
Calcium Around Cracks
Calcium buildup on elevator pit walls is a clear sign of an issue:
-
These deposits form when a significant amount of water seeps in from outside.
-
If left unaddressed, this water flow can damage elevator equipment, potentially leading to a complete shutdown.
Scrape and Paint Work
Rusted metal surfaces in the pit are a sign that flooding has occurred at that level:
-
This may also indicate that the walls are saturated with water.
-
If not addressed, there is a risk of further flooding and additional damage to elevator equipment.
