Elevator Pit Waterproofing — Toronto & the GTA
Below-grade waterproofing, crack injection and drainage that keep elevator pits dry, code-compliant and out of inspection trouble — for condominiums, commercial buildings and property managers across Toronto, the GTA and Southern Ontario.
How is an elevator pit waterproofed?
An elevator pit is waterproofed from the inside — by sealing the below-grade concrete walls and floor, injecting the cracks and cold joints that let water in, and adding a sump or drainage where groundwater is present — so the pit stays dry and passes inspection.
Because an elevator pit is the lowest point of the building, it sits below grade and often below the water table, so water is forced in under hydrostatic pressure. DryShield treats it with negative-side (interior) waterproofing on the pit walls and floor, polyurethane and epoxy crack injection for active cracks, tie-rod holes and cold joints, and sealing of any pipe or conduit penetrations. Where groundwater keeps returning, we add an elevator pit sump pump or drainage to manage it.
Elevator pits are regulated in Ontario, and standing water can trigger inspection deficiencies or take an elevator out of service. Keeping the pit dry protects the equipment, the building and your compliance.

Why elevator pits leak
An elevator pit is the lowest, most water-exposed point in the building. The water almost always comes from one of these:
Below the water table
The pit sits below grade — often below groundwater level — so it is under constant hydrostatic pressure.
Wall & floor cracks
Shrinkage and structural cracks in the pit walls and slab give water a direct path in.
Cold joints & tie-rod holes
Construction joints and formwork tie-rod holes are common, easily missed leak paths.
Pipe & conduit penetrations
Unsealed penetrations through the pit walls let water track straight through.
Failed original waterproofing
The pit was often never properly waterproofed, or the original system has aged out.
Rising water table & storms
Heavy rain and seasonal groundwater spikes overwhelm a pit that was already marginal.
What we do to waterproof an elevator pit
Pit wall & floor waterproofing
Negative-side (interior) waterproofing of the pit walls and slab to hold back groundwater.
Crack injection
Polyurethane and epoxy injection of active wall and floor cracks — see our commercial concrete crack injection service.
Cold joints & tie-rod holes
Construction joints and formwork tie-rod holes injected and sealed against water.
Pipe & conduit penetrations
Penetrations through the pit walls sealed and injected so they stop conducting water.
Sump pump & drainage
An elevator pit sump pump or drainage where groundwater keeps returning.
Shaft base & below-grade walls
Elevator shaft waterproofing at the base and adjoining below-grade walls.
Which elevator pit fix you need
| Situation | The right approach |
|---|---|
| A defined, active crack is leaking | Polyurethane or epoxy crack injection |
| General seepage through walls or floor | Negative-side pit waterproofing |
| Water keeps returning / high water table | Elevator pit sump pump and/or drainage |
| Leaks at a pipe or conduit penetration | Penetration sealing plus injection |
Most pits we treat need a combination — injection to stop the active leaks, negative-side sealing for general dampness, and a sump where groundwater is present.
Signs your elevator pit needs waterproofing
- ✓Standing water or persistent dampness in the pit
- ✓A sump pump that runs constantly or has failed
- ✓Rust on rails, buffers or pit equipment
- ✓Efflorescence (white mineral staining) on the pit walls
- ✓Musty odour or mould in the shaft
- ✓An elevator inspection flagged water in the pit
Water in an elevator pit is both a durability and a compliance problem — the sooner it is sealed, the less risk to your equipment and certificate.

What does elevator pit waterproofing cost?
Every pit is priced by scope after a site assessment — here is how the ranges break down:
| Scope | Typical basis | Notes |
|---|---|---|
| Crack injection | Per linear foot / per crack | Polyurethane or epoxy; fastest way to stop an active leak |
| Negative-side pit waterproofing | Per project | Interior sealing of pit walls and floor |
| Sump pit & pump / drainage | Per project | Where groundwater keeps returning |
| Penetration sealing | Per penetration | Pipe and conduit entries through the pit |
Property managers receive a written, itemized scope so the board or ownership can compare apples to apples. Request a free assessment for a firm number.

Elevator pit waterproofing FAQs
How do you waterproof an elevator pit?
From the inside. We seal the below-grade pit walls and floor with negative-side waterproofing, inject active cracks, cold joints and tie-rod holes with polyurethane or epoxy, seal pipe penetrations, and add a sump pump or drainage where groundwater is present. Every pit starts with a site assessment and a written scope.
Why is there water in my elevator pit?
Because the pit is the lowest point of the building, below grade and often below the water table, so groundwater is pushed in under pressure through cracks, cold joints, tie-rod holes and pipe penetrations. Heavy rain and seasonal water-table spikes make it worse. We trace the exact paths and seal them.
Is water in an elevator pit a code problem?
Yes. Elevator pits are regulated in Ontario and are required to be kept dry. Standing water can lead to inspection deficiencies and, in some cases, take the elevator out of service until it is corrected. Waterproofing the pit protects both the equipment and your compliance.
Can you fix it without shutting the elevator down for long?
Usually. We work from inside the pit and coordinate short access windows with your elevator contractor, so downtime is kept to a minimum. We schedule the work around the building and your maintenance provider.
Do you install a sump pump in the elevator pit?
Yes, where groundwater keeps returning. After sealing the cracks and walls, we can add an elevator pit sump pump or drainage to manage any residual water. We size and place it to keep the pit reliably dry.
Crack injection or a full pit waterproofing — which do I need?
It depends on the leak. A defined, active crack is best stopped with polyurethane or epoxy injection; general seepage through the walls or floor calls for negative-side waterproofing; a high water table may also need a sump. We recommend the right combination during the assessment.
Do you work with condo boards and property managers?
Yes. Most of our commercial work is for condominium corporations, property managers and building owners. We provide itemized written scopes, insurance certificates and schedules the board can approve and budget against.
