Negative-Side Elevator Pit Waterproofing in Vancouver, Burnaby, Richmond, Surrey, and the Fraser Valley
Overview
Fraser Valley Concrete waterproofs leaking elevator pits from the inside – negative-side repair – when the pit sits below the water table and the exterior membrane cannot be reached.

A Service That Lasts
Why elevator pits leak
The pit is usually the lowest point in the building. It sits in groundwater, collects construction water, and is full of cold joints, tie holes, and honeycomb that never got detailed at pour.
Typical paths:
- Cold joints between walls and the pit slab
- Shrinkage and stress cracks
- Honeycomb and poorly consolidated concrete
- Failed or missing positive-side membrane
- Pipe and drain penetrations
- Nearby excavation that changed the water table
Standing water in the pit is not a “nuisance.” It corrodes rails, cylinders, and electrical gear, grows mould, and turns into an elevator-contractor shutdown and a deficiency claim.
Service & Expectations
What to expect on site
Pits are tight. Noise, dust, and elevator downtime have to be planned. We coordinate access with the elevator company, work in the window you give us, and leave the pit dry enough to put the car back in service.
Quote is from a site look, not a phone guess. Standing water, active flow, and joint layout change the method.
How Fraser Valley Concrete Does It
Elevator Pit Repair Services

Negative-side waterproofing (what we actually do)
On an existing building you rarely get to dig the pit out and redo the exterior membrane. Repair is done from the wet face — the inside of the pit.
That is negative-side waterproofing. Water is still pushing in from the soil. The system has to stop active flow, then become part of the concrete.
We use Kryton crystalline systems (Krystol T1/T2, Krystol Plug, Krystol Bari-Cote) and compatible injection where the crack needs it:
- Isolate the pit with the elevator contractor. Confirm lockout and access.
- Find every active path — joints, cracks, honeycomb, penetrations — not just the puddle.
- Stop flowing water with hydraulic plug / rapid-set material. We would rather see the leak running than guess at a dry stain.
- Chase and pack joints and defects.
- Apply crystalline slurry so the concrete itself grows a watertight matrix (the crystal growth continues in the presence of moisture).
- Treat remaining cracks with injection where width or movement needs it.
- 360° inspection before we leave. Photos for the strata or PM file.
We do not sell a painted-on coating as a permanent pit repair.
The FVC Guarantee
Permanent Solutions for Elevator Pit Leak Repair
Kryton Krystol crystalline waterproofing reacts with moisture in the concrete and grows a dense crystal structure in the pores and capillaries. That is how a negative-side repair holds against hydrostatic pressure. We plug active flow first, pack joints and defects, apply the crystalline slurry, and inject cracks that still need it. We do not call a surface paint job a pit repair.
Who this page is for
- Property managers and strata councils with a wet pit or a deficiency list
- Elevator contractors who will not energize a flooded hoistway
- GCs and deficiency consultants closing a new building
- Parkade / below-grade remediation where the pit is one leak among several

FAQ
Can you waterproof a pit that is actively leaking?
Yes. Active flow is useful — it shows the path. We stop the flow first, then treat the concrete.
Is this the same as a basement waterproofing membrane?
No. A new pit should be waterproofed from the soil side (positive side) at construction. This page is for existing pits where that access is gone. We work from the interior.
Will the elevator be down?
Usually yes, for the work window. We plan that with the elevator contractor so the building is not surprised.
What materials do you use?
Kryton Krystol crystalline waterproofing and compatible plugs, patch mortars, and injection. The point is a repair that lives in the concrete, not a film that peels in a wet pit.
Do you warranty the work?
5 years on workmanship.
