Jet aircraft impose concentrated gear loads, thermal stress from engine run-up, and chemical attack from fuel and de-icing salts. Oshawa Concrete designs and pours aprons and taxiway sections to handle the full load spectrum, with slab thickness and reinforcement matched to your aircraft fleet, freeze-thaw-rated mix for Ontario winters, and aviation-grade joint sealing. Start with a free written estimate.
A small hangar apron may see fewer aircraft movements than a busy taxiway, but each landing concentrates the full weight of the aircraft on a small gear footprint. The slab must be engineered for that peak load, not an average. Thickness, rebar placement, and joint spacing all flow from the aircraft load analysis. Add Ontario's freeze-thaw cycle, and the concrete mix itself becomes critical: air entrainment, water-cement ratio, and curing all determine whether the slab survives five winters or spalls in two.
We start with the aircraft load spec and the site conditions, design the slab to the engineering, pour with a freeze-thaw-rated mix, and seal the surface and joints with aviation-rated products that resist jet fuel and de-icing fluid. The result is a pavement that handles the load and the climate.
We work from the aircraft specifications to determine slab thickness, reinforcement type and spacing, and joint pattern. The design accounts for the heaviest aircraft and the worst-case gear position.
Site prep and base installation
The apron area is excavated to subgrade, compacted, and the gravel base is placed at the engineered depth and re-compacted. Drainage slopes are set so water sheds away from the slab.
Formwork, rebar, and pour
Forms are set to the joint pattern, rebar and load-transfer dowels are placed per the design, and the freeze-thaw-rated concrete is poured, screeded, and finished to the specified surface texture.
Joint cutting and sealing
Control joints are saw-cut on schedule, cleaned, and sealed with aviation-rated joint sealant. The surface is sealed with a penetrating sealer rated for jet fuel and de-icing fluid exposure.
Common failure modes
Water Infiltration and Joint Failure Are the Top Apron Problems
We assess failed aprons regularly, and the pattern is consistent: water pools on the surface because drainage was not engineered, or joints were sealed with the wrong product and fail under freeze-thaw. Both lead to spalling at the joint edges and surface scaling within a few winters. Once water gets into the slab, the damage accelerates.
Our approach is to engineer drainage from the start, with slopes that move water to low points and away from the slab. We seal joints with aviation-rated sealant that resists both the chemical exposure and the thermal cycling.

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 Ontario 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.
