A documented elevator-pit sealing project at an anonymous off-site storage facility in the Pacific Northwest.
The documented challenge: standing water in an elevator pit
This case study concerns an anonymous off-site storage facility in the Pacific Northwest. The project documentation identified water intrusion and standing water in an elevator pit.
The documented condition was the starting point for a project-specific review. This article does not identify the facility or present the work as a one-size-fits-all solution for other buildings.
Why an individual assessment matters
The source document presents this as one documented project in the Pacific Northwest. An elevator pit with water intrusion needs to be reviewed in its own context before a building team decides on the next step.
A condition seen in one pit does not establish the right treatment for another property. True North Elevator recommends an individual assessment of the observed pit condition and practical remediation options.
A coordinated pit-sealing approach
For this project, the documented work included concrete work in the sump area. The project also included crystalline mortar at concrete cold joints in the pit.
Those steps describe the work recorded for this property. The appropriate scope for another elevator pit depends on its observed condition and an individual assessment.
- Document the standing-water or water-intrusion concern.
- Review the elevator pit and sump area in person.
- Discuss observed cold joints and the project-specific conditions.
- Identify practical next steps after the assessment.
Before and after the documented treatment
The before photo records standing water in the elevator pit. The after photo records the pit after the documented sump-area concrete work and treatment at the cold joints. These photos describe this project’s documented condition and work; they are not a promise of the same outcome for another property.


What property teams can take from this case
A water-intrusion concern in an elevator pit is a useful reason to begin a focused conversation with an elevator service provider. Sharing the observed condition helps the building team and service provider decide what should be reviewed in person.
This case is a documented example, not a promise of a particular result. Individual assessment is important because the observed condition and appropriate scope can differ from one property to another.
Request a pit sealing assessment
Every elevator pit is different. True North Elevator can review the observed water-intrusion concern, sump area, and cold joints in context and discuss practical next steps for the building.
