Aprons and taxiway sections at Regina airports take aircraft weight, jet engine exhaust, fuel and de-icing chemical exposure, and Saskatchewan's freeze-thaw cycles all at once. Regina Concrete designs and pours these slabs to the load spec, with the thickness, reinforcement pattern, and joint layout that match the actual aircraft fleet. We use freeze-thaw-rated mixes and aviation-grade sealers. Call for a free written estimate.
The slab thickness, reinforcement, and joint spacing all come from one place: the heaviest aircraft that will land on the apron, and where its gear will sit. A small hangar apron may see fewer aircraft movements than a busy taxiway, but the slab still has to handle the same point load from a heavy aircraft's main gear. We work from the aircraft load data and the engineer's design to set the concrete thickness and reinforcement.
Jet blast at engine run-up areas adds surface erosion risk, and Saskatchewan winters add freeze-thaw spalling risk if the slab is not sealed and drained properly. We specify a freeze-thaw-rated concrete mix with the right air entrainment, pour to the engineered thickness, and seal with aviation-rated products that resist jet fuel and de-icing fluid.
We review the aircraft fleet, the heaviest gear load, and the apron footprint, then work with the engineer to set slab thickness, reinforcement, and joint pattern for the actual loads.
Subgrade prep and base
The apron area is excavated to subgrade, compacted, gravel base placed at the engineered depth and compacted again, and grade checked for proper drainage slope.
Form, reinforce, and pour
Joint lines are formed per the design, load-transfer dowels placed where needed, and the freeze-thaw-rated concrete mix is poured, screeded, and finished to the specified surface.
Joint sealing and surface protection
Control joints are saw-cut on schedule and sealed with aviation-rated joint sealant, and the slab surface is sealed against jet fuel and de-icing fluid where the design calls for it.
Common failure modes
Joint Failure and Pooling Water Cause Most Apron Damage
When we assess failed aprons, the root cause is almost always one of two things: water pooling on the surface because drainage was not engineered in, or joints that were sealed with the wrong product or not sealed at all. Both lead to spalling at the joint edges and surface scaling across the slab over a few Saskatchewan winters.
We design drainage into the apron from the start, with slopes that shed water to low points, and we seal joints with aviation-rated sealant that resists jet fuel, de-icing fluid, and the freeze-thaw cycle. Coordinate with your broader aviation facility concrete work and the wider industrial concrete scope for the full site picture.
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 Saskatchewan 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.
