Suspended decks carry vehicles, snow, and road salt. The concrete must resist chloride penetration, the rebar must be protected from corrosion, and the slab must shed water rather than trap it. We build parking structures to the structural engineer's specifications, using low-permeability mixes, proper reinforcement cover, and protective sealers suited to Gatineau's freeze-thaw cycles. Free written estimate on every project.
Why Parking Deck Concrete Fails Without the Right Design
Road salt enters a parking structure through vehicle tires and melting snow. It dissolves into moisture, seeps through cracks in the slab, and attacks the reinforcing steel. Corroded rebar expands, spalls the concrete, and compromises the structural integrity of the deck. This is why parking structures demand chloride-resistant concrete mixes, thicker reinforcement cover, and ongoing sealer maintenance.
Every parking deck we pour follows the structural engineer's specifications exactly. We specify low-permeability concrete with corrosion inhibitors, place rebar with the engineered cover depth, and apply the specified protective sealer once the slab cures. The maintenance schedule is documented and handed to the property owner so the structure performs for decades.
The structural engineer's plans define slab thickness, reinforcement layout, cover depth, mix design, and load paths. We confirm our forming and pour strategy against these drawings before any work begins on site.
Set forms and stage reinforcement
Suspended deck forms are installed with the engineered camber, rebar is placed at the specified cover depth with corrosion inhibitors, post-tension cables are installed if required, and the layout is verified by the engineer before concrete is ordered.
Place chloride-resistant concrete
The concrete mix is air-entrained, low-permeability, and includes corrosion inhibitors as specified. It is placed, consolidated, and finished to the deck slope so meltwater sheds and does not pond against the slab surface.
Apply sealer and document maintenance
Once the slab cures, the specified chloride-resistant sealer is applied. The maintenance and reseal schedule is documented in writing and handed to the property owner for long-term care.
Ongoing protection
Sealer Reapplication Keeps Parking Decks Sound
A properly built parking deck will last 30+ years if sealer maintenance happens on schedule. UV exposure and freeze-thaw cycles wear protective coatings faster in Gatineau than in milder climates, so reapplication every 2-4 years is typical. We provide the maintenance schedule with the project handoff and return on schedule to reseal the deck.
Skipping maintenance accelerates deterioration. Unprotected concrete allows chloride penetration, rebar corrosion begins, and spalling follows within 10-15 years. We coordinate scheduled maintenance with parking structure repair work and adjacent parking lot services so the entire property is maintained as a system.
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 Gatineau 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 Gatineau 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.

★★★★★
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.
