Landing gear concentrates enormous point loads on a small footprint. Add jet blast, fuel spills, de-icing chemicals, and British Columbia's freeze-thaw cycle, and the slab must be engineered to survive all of it. Abbotsford Concrete designs and pours aprons and taxiway sections to the aircraft load spec, with the right concrete mix, joint pattern, and surface sealing for aviation duty. Free written estimate on every project.
A small regional hangar apron carries the same landing-gear load as a major taxiway, just less often. The concrete slab thickness, reinforcement pattern, and joint spacing all derive from the heaviest aircraft that will use the apron and the worst-case gear position. We do not guess at thickness or follow a generic standard; the engineer specifies the slab, and we pour to that spec.
Freeze-thaw durability adds another layer. British Columbia winters cycle concrete through freeze and thaw repeatedly. The concrete mix must have the right air entrainment and water-cement ratio to survive that cycling without spalling or scaling. Jet fuel, de-icing fluid, and thermal shock from engine run-up zones all demand a sealer rated for aviation exposure.
We review the engineering with the aircraft fleet and gear loads, confirm slab thickness, reinforcement, and joint pattern, and verify the design against the actual site conditions and drainage.
Excavate and compact subgrade
The apron footprint is excavated to the engineered subgrade depth, compacted in lifts, gravel base is placed and compacted again, and final grade is verified for proper drainage slope.
Form, reinforce, and pour
Control joints are formed per the engineering layout, load-transfer dowels are set where required, and the freeze-thaw-rated concrete mix is poured, screeded, and finished to the specified surface profile.
Saw-cut joints and seal
Control joints are saw-cut on schedule to prevent random cracking, sealed with aviation-rated joint sealant, and the surface is sealed against jet fuel and de-icing fluid exposure.
Common failure modes
Poor Drainage and Joint Sealing Cause Most Apron Failures
We assess failed aprons regularly, and the pattern is consistent. Water pools on the surface because drainage was not engineered into the slab, or joints were sealed with the wrong material and failed under freeze-thaw. Both lead to spalling at joint edges and surface scaling across the apron within a few winters.
We design drainage from day one, with slopes that shed water to engineered low points and perimeter drains if needed. Joints are sealed with aviation-rated sealant that resists jet fuel, de-icing fluid, and the freeze-thaw cycle. Coordinate with your hangar floor coating work and broader industrial concrete services for the full facility 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 British Columbia 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.
