Aircraft Apron & Taxiway Concrete Built for Gatineau
Aprons and taxiway sections take aircraft weight, jet engine heat and chemical exposure, then freeze and thaw through Quebec winters. Gatineau Concrete sizes the slab, reinforces the joints, and seals the surface to handle all three. Every project is engineered to the actual aircraft fleet, poured with a freeze-thaw mix, and quoted in writing before work starts.
An apron is not a parking lot. The slab must carry concentrated gear loads from aircraft that can weigh hundreds of thousands of pounds, with the load concentrated on a few small contact patches. That load profile drives the thickness, the reinforcement pattern, and the joint spacing. Skip the engineering and the slab will fail at the joints within a few seasons.
Add Quebec winters and jet fuel exposure, and the concrete itself must be mixed differently. Air entrainment in the mix design lets water freeze inside the concrete matrix without spalling the surface. The sealer must resist jet fuel, de-icing fluid, and thermal shock from engine run-up zones. We specify all three from the start: the slab thickness from the aircraft load, the mix design from the freeze-thaw exposure, and the sealer from the chemical environment.
We start with the aircraft specs: weight, gear configuration, and the heaviest aircraft that will use the apron. The engineer calculates slab thickness, reinforcement, and joint pattern from that load profile.
Prepare the subgrade and base
The apron footprint is excavated to the engineered subgrade depth, compacted in lifts, and the gravel base is placed and compacted again. Grade is verified for proper drainage before forming begins.
Form, reinforce, and pour the slab
Forms are set to the engineered joint pattern, load-transfer dowels are placed where the design calls for them, and the freeze-thaw-rated concrete mix is poured, screeded, and finished to the specified surface.
Saw, seal, and cure
Control joints are saw-cut on schedule, sealed with aviation-rated joint sealant, and the surface is sealed against jet fuel and de-icing fluid. The slab cures under controlled conditions before aircraft operations resume.
Common failure modes
Joint Failure and Pooling Water Are the Apron Killers
We see two patterns in failed aprons: joints that were sealed with the wrong material or not sealed at all, and drainage that lets water pool on the surface. Both lead to spalling and scaling within a few winters as water freezes in the concrete and breaks it apart from the inside.
Our approach is to engineer drainage into the apron from day one, with slopes that shed water to low points and perimeter drains where needed. Joints are sealed with aviation-rated sealant that resists jet fuel, de-icing fluid, and the freeze-thaw cycle. We also coordinate with adjacent concrete supply and concrete pumping services to ensure the whole site concrete system works together.
Slab thickness, joint pattern, jet blast and freeze-thaw mix design.
Several inches to a foot or more, depending on the heaviest aircraft served. Engineering analysis from the aircraft gear load drives the spec; we will not pour thinner than the engineering specifies even if budget pressure exists.
For aprons that serve heavier aircraft or have larger slab panels, yes. Dowels transfer load across joints so the slab edges do not fail individually. The engineer specifies dowel size and spacing based on the joint geometry and load profile.
Aviation-rated penetrating sealers that resist jet fuel, de-icing fluid, and thermal cycling. We spec from the aviation sealer chart based on the actual exposure your apron sees, including engine run-up locations if relevant.
Air entrainment is the key, the right air content in the cured concrete lets water freeze inside the matrix without spalling. Combined with the right water/cement ratio and admixtures, the mix resists Quebec winters.
From a few weeks for a small new apron to multi-month projects for taxiway connections requiring engineering and coordination with airport operations. The full schedule is in the quote.
New apron poured to engineering for our heaviest based aircraft. Joints dowelled, sealed properly, freeze-thaw mix verified. Three winters in, zero surface scaling, zero joint failure.

They knew the aviation specs cold, coordinated with our engineer on slab thickness and joint pattern. The result has held through heavy aircraft turn and full winter cycling.

Apron expansion to handle a new based aircraft. Engineered specifically for the new load, tied into existing pavement cleanly. The transition joint has held perfectly.

Apron with engine run-up area required jet-blast-rated sealer. They specified the right product, applied to spec, the surface has held with no erosion at the run-up zone.
