Aircraft hangar floors face chemicals no other industrial floor sees: jet fuel spills, hydraulic fluid leaks, skydrol, de-icing fluids, and aircraft tire wear. Gatineau Concrete installs aviation-rated hangar floor systems engineered for those exposures, with the slab prep, system spec, and joint detail that match aircraft maintenance reality. Every project starts with a free written estimate.
Aviation chemistry is unique. Skydrol hydraulic fluid is aggressively reactive and dissolves standard epoxy quickly. Jet fuel and avgas degrade other coatings over time. De-icing fluids in winter add a separate chemistry. The right hangar floor matches all of these in one system, typically a urethane or specialty aviation-spec epoxy with the slab prep and topcoat to last decades.
Aircraft loads add another factor. Tow tractors with small hard wheels concentrate load similar to forklifts; aircraft tires sit on the floor with substantial weight at specific points. We engineer the slab and coating for both moving and parked loads, with reinforcement at known tire contact zones for parked aircraft.
We confirm with maintenance operations exactly which fluids the hangar handles (Jet A, avgas, Skydrol grades, hydraulic, de-icing), the spill frequency, and the cleanup chemistry, then spec the system that matches all exposures.
Diamond-grind and remediate
The hangar slab is diamond-ground to the system's prep profile, contaminated zones from prior fuel or fluid spills are remediated (sometimes requiring deeper removal), and cracks are repaired with bonded high-strength materials.
Install aviation-spec system
The matched system (urethane cement for severe Skydrol exposure, aviation-rated epoxy for general use) is installed at engineered thickness with aggregate broadcast for slip resistance in service areas.
Joint, seal, and document
Control joints are filled with chemical-resistant semi-rigid filler, the topcoat seals the system, and the chemical-resistance rating is documented for facility records and any compliance review.
Aircraft tow loads
Tow Tractor Point Loads Often Get Missed
The aircraft itself is heavy but spread across multiple gear positions. The tow tractor that moves aircraft in and out can be the worse load case, small solid wheels concentrating substantial weight at every turn point. We engineer the coating for tow tractor loads as the worst case, which makes the coating bulletproof under the lighter aircraft loads.
Coordinate with adjacent apron and taxiway work outside the hangar door and with the rest of aircraft hangar services across the facility.
Skydrol resistance, tow tractor loads, joint fillers and aviation compliance.
Aviation chemicals (especially Skydrol) attack standard epoxy systems aggressively. Combined with tow tractor point loads and aircraft tire contact patches, the spec has to match a unique exposure profile that other commercial floors do not see.
If the hangar handles aircraft with Skydrol hydraulic systems (most modern commercial and many corporate), yes. Skydrol-rated urethane cement is the typical answer; the wrong system dissolves quickly under Skydrol contact.
Glycol-based de-icing fluids are part of the chemical exposure profile in Gatineau hangars. We spec the system for those alongside the aviation hydraulics so winter operations do not degrade the floor.
Yes, the joint filler has to be chemical-resistant to the same aviation fluids the coating handles. Standard polyurea filler can degrade under Skydrol; we use chemical-resistant variants in aviation environments.
A typical hangar takes a week or two from prep through cure, with the hangar offline during the work. Larger MRO facilities stretch to multi-week phased installs. The schedule is built around maintenance operations.

What Gatineau Operations Say About Their Hangar Floors
Skydrol-rated urethane install in our maintenance hangar. Three years of regular hydraulic spills, zero coating failure at any spill point. Worth the spec premium over standard epoxy.

FBO Manager, Gatineau Airport
★★★★★
Engineered for our tow tractor loads, not just aircraft loads. The coating has held perfectly at every tow turn point, where the previous floor had failed within months.

MRO Operations, Ottawa
★★★★★
Coordinated install during a scheduled maintenance downtime. Hangar offline only for the cure window, back in service on schedule. Real coordination with operations.
Q. A5
Corporate Hangar Owner, Barrhaven
★★★★★
Documented chemical-resistance rating for our facility compliance file. Auditor accepted without questions. The documentation matters in aviation.
