Parking decks sit above ground on columns and beams, carrying live loads from vehicles and snow. Salt from winter roads seeps through cracks and attacks the rebar. We build decks to the structural engineer's specifications using chloride-resistant concrete, proper reinforcement cover, and protective sealers that hold up in our freeze-thaw climate. Free written estimate on every project.
How Salt Destroys Parking Decks and How We Stop It
Winter salt on vehicle tires melts into brine that runs down through the slab. If the concrete is porous or the rebar sits too close to the surface, chloride ions reach the steel and corrosion begins. Rust expands, spalls the concrete, and the structural integrity fails. A deck that should last 50 years can be compromised in 15 if the wrong mix or protection is used.
We specify low-permeability, air-entrained concrete with corrosion inhibitors, place rebar with engineered cover depth, and seal the deck surface with penetrating or membrane systems that shed water and block chloride ingress. The maintenance schedule is documented and handed to the owner so resealing happens on time.
Our approach applies across all parking work, from ground-level lots to multi-level structures. Where a parking deck repair is needed on an existing structure, we follow the same chloride-resistant protocol.

Construction sequence
Pouring a Parking Deck Slab in Oshawa
Review engineer's drawings and specs
The structural engineer specifies the slab thickness, reinforcement layout, concrete mix design, and live load capacity. We confirm our forming and pour plan against those drawings before any work begins on site.
Set forms and place rebar
Suspended deck forms are installed with the correct camber, rebar is positioned at the engineered cover depth with corrosion inhibitors, and post-tension cables are installed if the design calls for them. Layout is verified before concrete arrives.
Pour and finish the slab
Chloride-resistant concrete is placed, consolidated to remove air voids, and finished with a slope so meltwater runs off rather than pooling. The slab is cured per the engineer's schedule before traffic or loads are applied.
Apply sealer and hand off maintenance
Once cured, the deck is sealed with the specified chloride-resistant product. A written maintenance and reseal schedule is provided so the owner knows when to reapply protection and keep the structure performing.
Ongoing protection
Sealer Reapplication Keeps Decks Performing
A parking deck built right will perform for 40+ years if the sealer is reapplied every 3-5 years. UV and freeze-thaw cycles degrade the protective coating, and once it fails, chloride penetrates again. Skipping maintenance turns a sound structure into a failing one.
We deliver a maintenance schedule with every project and return on intervals to reseal the deck. We also coordinate with curb and gutter work and adjacent site concrete so drainage and protection work together. Our commercial floor expertise extends to deck overlays and repairs on existing structures.
Engineered design, chloride resistance, sealer maintenance and live-load specs.
Yes. Structures use lower-permeability, chloride-resistant mixes with corrosion inhibitors and more reinforcement protection. Ground-level lots take chloride exposure but the rebar is less critical to building structure; in a deck, rebar corrosion is structural failure.
Penetrating silane or siloxane sealers and traffic-bearing membrane systems are common, depending on the deck spec. Reapplication every few years is typical in Oshawa because UV and freeze-thaw wear sealers faster than in milder climates.
Both. We pour decks on new parking-structure construction under the engineer's drawings, and we perform structural concrete repair on existing structures where spalling, corrosion, or joint failure has begun. The scope drives the approach.
The structural engineer designs the slab and reinforcement for the specified live load (passenger vehicles, fire access, snow load). We follow the engineered drawings exactly; the load capacity is a structural property of the design, not something we adjust on site.
From several weeks for a single-deck overlay to many months for a full structure. The engineered project plan drives the timeline; the full schedule is in the quote and coordinated with the engineer and general contractor.

What Oshawa Operations Say About Their Parking Structures
Multi-level structure repair after 20 years of service. They worked under the engineer's drawings, did the spall repair properly, applied the new deck sealer. Structure is good for another decade plus.

★★★★★
New structure pour for an office complex. Chloride-resistant mix, every cover-depth verified, sealer applied on schedule. Property owner is comfortable signing off on the long-term maintenance plan they delivered.

Facilities Director, Toronto
★★★★★
Tight coordination with the structural engineer on every pour. No improvisation, every detail to the drawings. The engineer remarked on how clean the work was during inspections.

★★★★★
Deck overlay during off-hours to keep the structure open for shoppers. Sequenced perfectly with our operations, never closed more than needed. Real understanding of retail timing.
