Services / Parking Garage Restoration
Parking garage restoration in Toronto & the GTA
Underground and above-grade structures repaired and waterproofed, with residents still parking.
The problem
Road salt is what destroys a garage
Chloride from winter slush soaks into the deck, reaches the reinforcing steel and corrodes it. Corroding rebar expands and cracks the concrete from the inside.
By the time you see spalling from the level below, the repair is far larger than it was three years earlier. The fix is to remove the contaminated concrete, restore the steel, replace the concrete, then keep water out with a traffic membrane.
Scope of work
What the contract covers
| Investigation | Delamination survey. Chain drag and hammer sounding to map hollow areas and produce real quantities. |
|---|---|
| Partial-depth repair | Saw-cut and chip-out. Contaminated concrete removed to sound material, steel cleaned, repair mortar placed. |
| Full-depth repair | Slab replacement through the section. Forming and shoring from below, rebar replaced and lapped. |
| Columns & beams | Vertical and overhead repair. Formed or hand-applied, including jacketing where specified. |
| Expansion joints | Joint system replacement. Blockout repaired, new system to the specified detail. |
| Crack treatment | Routing and sealing. Epoxy injection on structural cracks where drawings call for it. |
| Waterproofing | Traffic deck membrane. Shot blast, prime, base coat, aggregate broadcast, top coat to specified thickness. |
| Drainage | Drain and slope correction. So water leaves the deck instead of sitting on it. |
| Reinstatement | Line painting and signage. Stalls, numbering, accessible spaces, fire routes. |
Phasing
Residents keep parking
- Phasing drawing issued before we mobilize
- Draft resident notices management can send
- Ramps sequenced so there is always a route in
- Night and weekend work on tight sites
- Fire route and life safety access maintained
Questions
Common questions
How long does it take?
Six to ten weeks for a single level with moderate deterioration. A large multi-level structure phased to protect parking can run a full season. Phasing drives the schedule more than the volume of work does.
Why does the price change during the project?
Restoration is tendered on unit rates against estimated quantities, because the true extent of deterioration is only known once the deck is opened. If quantities exceed the estimate, the value rises. That is normal. Learning about it at the end is not, which is why we log installed quantities daily with your consultant.
Do we need an engineer?
For anything structural, yes. A restoration engineer produces the condition survey, the details and the specification, and reviews the work on the board's behalf. It usually pays for itself in better pricing and fewer disputes.
How long should the repair last?
A properly executed restoration with a maintained traffic membrane gives a long service cycle. Coatings are a wear surface and need inspection and touch-up, particularly at ramps and turning areas.
