Aprons and taxiway sections at aviation facilities must handle concentrated gear loads, jet fuel and de-icing chemical exposure, plus the relentless freeze-thaw cycling of Michigan winters. Detroit Concrete designs and pours these slabs to the aircraft load spec, with the thickness, reinforcement pattern, and freeze-thaw-rated mix that keeps the pavement intact through years of heavy use and seasonal stress. Every project includes a free written estimate and firm schedule.
A small hangar apron carries the same concentrated load as a major taxiway, just less frequently. The slab thickness, reinforcement, and joint spacing all flow from the aircraft load case. Jet blast at engine run-up zones adds surface erosion risk, and Michigan's winter freeze-thaw multiplies any drainage or sealing mistake into spalling and joint failure within a few seasons.
We start with the aircraft load engineering, specify a freeze-thaw-rated concrete mix with proper air entrainment, form and pour to the engineered joint pattern with load-transfer dowels where needed, and seal the surface against jet fuel and de-icing fluid. The result is a slab that handles the load and the climate.
We work from the aircraft specifications to determine slab thickness, reinforcement, and joint layout. The design is sized for the heaviest aircraft and the worst-case gear position, not a generic standard.
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. Grade is verified for proper drainage before forming begins.
Forming, reinforcement, and pour
Joint lines are formed per the design, rebar and load-transfer dowels are positioned, and the freeze-thaw-rated concrete mix is poured, screeded, and finished to the required surface profile.
Joint sealing and surface protection
Control joints are saw-cut on schedule and sealed with aviation-grade joint sealant. The slab surface is sealed against jet fuel and de-icing fluid exposure per the design specification.
Common failure modes
Poor Drainage and Unsealed Joints Cause Most Apron Failures
When we assess failed aprons, the root cause is almost always poor drainage that allows water to pool and freeze on the surface, or joints that were never sealed or sealed with the wrong material. Both lead to spalling at joint edges and surface scaling across the slab within a few winters.
We design drainage into the apron from the start, with slopes that shed water to engineered low points and away from the slab. Joints are sealed with aviation-rated sealant that resists jet fuel, de-icing chemicals, and the freeze-thaw cycle. For broader site coordination, see our aviation facility concrete work and the full industrial concrete service menu.
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 Michigan 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.
