Aviation & Hangar Epoxy Flooring Toronto: Heavy-Duty, Fuel-Resistant & Operationally Reliable Flooring Systems
Toronto Precision Epoxy Flooring installs aviation and hangar epoxy flooring systems engineered for high-load aircraft environments where fuel exposure, mechanical stress, and operational safety are critical. These systems form seamless, non-porous, and fuel-resistant surfaces designed for aircraft hangars, MRO facilities, and ground support zones across Toronto. Built to withstand Jet A and Avgas fuel, hydraulic fluids such as Skydrol, de-icing chemicals, and continuous equipment traffic, our flooring systems maintain adhesion, surface hardness, and chemical resistance under sustained aviation use.
Aircraft hangars impose extreme point loads and rolling loads that exceed typical commercial demands. Landing gear can exert concentrated pressures exceeding 200–300 psi, while tow tractors and ground support equipment introduce constant abrasion and impact. Concrete substrates are porous and can transmit moisture vapour (~3–10+ lbs/1000 sq ft/24 hrs, ASTM F1869), which can lead to coating failure if not properly mitigated. Without proper system design, coatings may soften under fuel exposure, delaminate under heavy loads, or degrade from repeated thermal cycling and chemical contact.
Aviation-grade epoxy flooring systems typically incorporate moisture-tolerant epoxy primers, high-build 100% solids epoxy or epoxy mortar base coats (3–6 mm+), and chemical-resistant topcoats such as polyurethane or polyaspartic. In high-exposure zones, novolac epoxy systems are used for superior resistance to hydrocarbons and aggressive aviation fluids. Slip-resistant broadcast systems with aluminum oxide or quartz aggregates can be integrated to meet safety requirements, while maintaining a dense, cleanable surface. These systems are designed to deliver compressive strengths exceeding 10,000 psi, high abrasion resistance, and long-term durability under continuous aircraft operations.
We provide aviation and hangar epoxy flooring services throughout Toronto and the Greater Toronto Area, including facilities near Pearson International Airport, Buttonville Municipal Airport, and surrounding industrial aviation hubs. Service areas include Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Milton, Pickering, Ajax, Whitby, Oshawa, and nearby logistics and aerospace zones. Every installation is tailored to aircraft specifications, facility operations, and long-term performance requirements in high-demand aviation environments.

Aviation & Hangar Epoxy Flooring Applications
Aviation and hangar flooring systems are engineered for environments exposed to aircraft loads, fuel contact, and continuous mechanical traffic. Floors must withstand point loads exceeding 200–300 psi from landing gear, rolling loads from ground support equipment, and chemical exposure from Jet A, Avgas, hydraulic fluids, and de-icing agents. High-build 100% solids epoxy, epoxy mortar, and novolac systems are commonly specified to deliver compressive strengths >10,000 psi, low permeability, and long-term resistance to abrasion, impact, and chemical degradation under active aviation operations.
Aircraft Hangars & Maintenance (MRO) Facilities
Hangars and MRO environments require flooring systems that resist heavy aircraft loads, dropped tools, and continuous equipment movement. High-build epoxy or epoxy mortar systems (3–6 mm+) provide structural durability, while polyurethane or polyaspartic topcoats enhance abrasion resistance and protect against fuel spills and hydraulic fluid exposure. Seamless finishes eliminate weak points, maintaining surface integrity under constant operational stress.
Fueling, Washdown & De-icing Areas
Fueling zones and wash bays are exposed to hydrocarbons, glycol-based de-icing fluids, and frequent washdowns. Novolac epoxy and chemical-resistant urethane systems are specified for their superior resistance to aggressive chemicals and solvent exposure. Slip-resistant aggregates such as aluminum oxide are integrated to maintain traction in wet conditions without compromising cleanability or surface density.
Ground Support Equipment & Service Bays
Areas supporting tow tractors, belt loaders, and service vehicles require flooring systems designed for continuous rolling loads and abrasion. Broadcast epoxy systems with quartz or aluminum oxide aggregates increase wear resistance and surface hardness, preventing premature coating wear from steel wheels and heavy-duty equipment while maintaining a uniform, serviceable surface.
Parts Storage, Tooling & Logistics Areas
Storage and staging zones experience moderate rolling traffic and require durable, low-maintenance surfaces that resist dusting and surface wear. Seamless epoxy systems reduce particulate generation, improve cleanability, and maintain consistent performance under ongoing material handling operations.
Perimeter Zones, Apron Interfaces & Access Points
Transition areas between hangars and exterior aprons are subject to thermal cycling, moisture intrusion, and contamination tracking. Moisture-tolerant epoxy primers combined with flexible or UV-stable topcoats help maintain adhesion and prevent cracking or delamination at entry points. Seamless systems with consistent thickness eliminate weak transitions and support long-term durability in high-traffic access zones.
Benefits of Aviation & Hangar Epoxy Flooring
Aviation and hangar flooring systems are engineered for environments subjected to heavy aircraft loads, fuel exposure, and continuous mechanical traffic. Unlike standard commercial or light industrial floors, these systems must resist hydrocarbons, withstand point loads exceeding 200–300 psi, and maintain structural integrity under constant rolling equipment and thermal cycling. High-performance systems such as high-build 100% solids epoxy, epoxy mortar, and novolac coatings are used to create dense, impact-resistant, and chemically stable surfaces for long-term aviation operations.
Aviation & Hangar Epoxy Flooring Systems
Aviation and hangar facilities require flooring systems engineered to withstand aircraft loads, hydrocarbon exposure, and continuous mechanical traffic. These systems are installed as seamless, multi-layer builds incorporating mechanical surface preparation (typically CSP 3–5), moisture-tolerant epoxy primers, high-build epoxy or epoxy mortar base layers, and chemical-resistant topcoats. System specifications are driven by aircraft type, load requirements, fuel exposure levels, and operational conditions to ensure long-term adhesion, abrasion resistance, and chemical durability in active aviation environments.
High-Build Epoxy & Epoxy Mortar Systems for Aircraft Load Conditions
High-build 100% solids epoxy and epoxy mortar systems are typically installed at 2–6 mm+ to handle extreme point loads from aircraft landing gear exceeding 200–300 psi. When applied over properly prepared CSP 3–5 profiles, these systems deliver compressive strengths >10,000 psi and high impact resistance, preventing surface deformation, cracking, and wear under heavy aircraft movement and maintenance operations.
Fuel-Resistant Novolac Epoxy Systems for Hydrocarbon Exposure
In areas exposed to Jet A, Avgas, hydraulic fluids (e.g., Skydrol), and solvents, novolac epoxy systems are specified for their high cross-link density and chemical resistance. These systems prevent softening, staining, and long-term resin degradation under repeated fuel spills and chemical exposure, maintaining structural and surface integrity in fueling and maintenance zones.
Broadcast Aggregate Systems for Abrasion & Slip Resistance
Quartz or aluminum oxide broadcast systems are incorporated into epoxy builds to improve abrasion resistance and traction in high-traffic areas. Installed at ~3–4 mm, these systems withstand continuous rolling loads from tow tractors, forklifts, and ground support equipment while maintaining a durable, serviceable surface that resists premature wear.
Moisture-Tolerant Primer Systems (MVT Control)
Concrete slabs in hangars can transmit moisture vapour (~3–10+ lbs/1000 sq ft/24 hrs, ASTM F1869), which can compromise coating adhesion. Moisture-tolerant epoxy primers are applied where required to control vapour transmission and prevent osmotic blistering, delamination, and bond failure under sealed, high-performance flooring systems.
Polyurethane & Polyaspartic Topcoat Systems
Protective topcoats are applied at approximately 6–12 mils to enhance abrasion resistance, UV stability, and chemical protection. Polyurethane systems provide flexibility and wear resistance under heavy traffic, while polyaspartic coatings offer rapid cure times and high durability, making them suitable for phased installations in operational hangars.
Seamless Integration, Joint Stabilization & System Continuity
Control joints and cracks are treated using epoxy fillers or polyurea joint systems to maintain load transfer and prevent edge deterioration under aircraft movement. Seamless system integration across slabs, joints, and transitions ensures uniform thickness, eliminates weak points, and supports long-term performance in high-demand aviation environments.
Aviation & Hangar Epoxy Flooring Layers & Materials
Aviation and hangar epoxy flooring systems are installed as engineered, multi-layer builds designed to withstand aircraft loads, hydrocarbon exposure, and continuous mechanical traffic. These systems are constructed to resist Jet A and Avgas fuel, hydraulic fluids such as Skydrol, and de-icing chemicals while maintaining adhesion under heavy point loads and thermal cycling. System design is driven by aircraft weight, traffic frequency, chemical exposure, and moisture conditions to ensure long-term durability, impact resistance, and operational reliability in active hangar environments.
1. Surface Preparation & Concrete Profiling (CSP)
Concrete is mechanically prepared to remove contaminants and achieve the required surface profile for proper adhesion. (see more details in Surface Preparation section)
2. Moisture-Tolerant Primer & Fuel-Resistant Barrier Layer
A two-component moisture-tolerant epoxy primer is applied at approximately 6–12 mils to penetrate and seal the concrete substrate while establishing a high-strength bond. In hangar environments where slabs may exhibit moisture vapour transmission (~3–10+ lbs/1000 sq ft/24 hrs, ASTM F1869), primers are specified to prevent osmotic blistering and adhesion loss. In fuel-exposed areas, this layer also acts as an initial barrier against hydrocarbon intrusion, supporting long-term system stability beneath heavy-duty coatings.
3. Base Layer (High-Build Epoxy, Novolac Epoxy, or Epoxy Mortar)
The base layer provides structural load-bearing capacity and primary chemical resistance. High-build 100% solids epoxy systems are typically installed at 2–4 mm to create dense, non-porous surfaces capable of withstanding aircraft traffic. In areas with heavy point loads or substrate damage, epoxy mortar systems installed at 3–6 mm+ deliver compressive strengths exceeding 10,000–14,000 psi and superior impact resistance. For fueling and maintenance zones exposed to Jet A, Avgas, and hydraulic fluids, novolac epoxy systems are specified for their high cross-link density and resistance to hydrocarbon attack.
4. Functional Layer (Abrasion Resistance, Load Distribution & Slip Control)
Functional system components are integrated to enhance wear resistance and safety under continuous equipment traffic. Broadcast systems using quartz or aluminum oxide aggregates are applied within the epoxy matrix to increase abrasion resistance and surface hardness, particularly in areas with tow tractors, forklifts, and ground support equipment. Surface profiles are engineered to provide slip resistance in fuel- or fluid-prone zones while maintaining a cleanable, serviceable finish suitable for operational efficiency.
5. Protective Topcoat & Long-Term Performance Layer
Protective topcoats are applied at approximately 6–12 mils using polyurethane or polyaspartic coatings to enhance chemical resistance, UV stability, and abrasion performance. These layers protect against fuel spills, hydraulic fluid exposure, tire wear, and thermal cycling from hangar door operation. The result is a sealed, high-performance surface that maintains adhesion, resists staining and surface degradation, and supports long-term durability under continuous aviation use.
Aviation & Hangar Epoxy Flooring Surface Preparation
Aviation and hangar environments require concrete preparation processes engineered for heavy aircraft loads, fuel exposure, and long-term coating adhesion under continuous mechanical traffic. Floors are routinely exposed to Jet A, Avgas, hydraulic fluids (e.g., Skydrol), de-icing chemicals, and high-load equipment movement. Proper surface preparation ensures the substrate achieves required bond strength, removes hydrocarbon contamination, and supports high-build resinous systems that maintain adhesion and structural integrity under extreme operational conditions.
1. Mechanical Grinding & Concrete Surface Profiling (CSP)
Concrete is mechanically prepared using industrial diamond grinding or shot blasting to achieve the required concrete surface profile (CSP 3–5 for high-build systems, CSP 4–6 for epoxy mortar). This process removes laitance, curing compounds, and embedded contaminants while opening the pore structure for mechanical interlock. Hangar slabs typically require compressive strengths ≥3,500–5,000 psi, with pull-off adhesion values of ≥250–350 psi after preparation to ensure coating performance under aircraft loads and heavy equipment traffic.
2. Removal of Fuel Residues, Oils & Embedded Contaminants
Hangar floors are frequently contaminated with hydrocarbons, lubricants, and maintenance fluids that penetrate the concrete matrix. These contaminants must be fully removed using mechanical grinding, degreasing agents, and, where required, thermal or chemical remediation methods. Any residual contamination acts as a bond breaker, increasing the risk of coating delamination, softening under fuel exposure, and premature system failure.
3. Removal of Existing Coatings & Substrate Correction
Existing coatings, sealers, and failed systems must be completely removed to expose sound concrete. Surface defects such as cracking, spalling, and joint edge deterioration are repaired using epoxy patching compounds or epoxy mortar systems. In areas subjected to heavy aircraft loads, localized resurfacing at 3–6 mm+ may be required to restore structural integrity and create a uniform substrate capable of supporting high-build flooring systems.
4. Surface Leveling, Drainage Optimization & Transition Preparation
Hangar floors require tight flatness tolerances and controlled drainage to manage fluid runoff from fueling and washdown activities. Grinding, leveling, and localized resurfacing are performed to eliminate slab irregularities, joints, and transition points that can trap liquids or create impact stress zones. Where required, slope-to-drain systems (typically 1–2%) are incorporated to direct fluids away from operational areas while maintaining a seamless, traffic-ready surface.
5. Moisture Evaluation, Vapour Control & Final Conditioning
Concrete slabs are evaluated for moisture vapour transmission using ASTM F2170 (in-situ RH) or ASTM F1869 (calcium chloride). Hangar slabs may exhibit moisture levels of ~3–10+ lbs/1000 sq ft/24 hrs, which must be addressed prior to coating installation. Moisture-tolerant epoxy primers are applied where required to prevent osmotic blistering and adhesion loss. Final preparation includes industrial vacuuming and controlled cleaning to ensure a dust-free, contaminant-free substrate ready for high-performance aviation flooring systems.
Effective surface preparation in aviation environments focuses on achieving a structurally sound, contaminant-free substrate with consistent surface profile and bond strength. When executed to specification, the flooring system resists fuel exposure, heavy loading, and continuous operational wear while maintaining long-term performance in high-demand hangar conditions.
Why Aviation & Hangar Epoxy Flooring Systems Fail
Aviation flooring systems are exposed to a combination of heavy aircraft loads, hydrocarbon contamination, and continuous mechanical traffic. Failures rarely result from a single issue—most occur when surface preparation, system chemistry, or build thickness does not match the demands of aircraft operations, fuel exposure, and environmental conditions. In hangar environments, even minor specification gaps can lead to rapid coating breakdown under load and chemical attack.
1. Inadequate Surface Preparation & Fuel-Contaminated Substrates
Failure to achieve the correct concrete surface profile (CSP 3–5 for coatings, CSP 4–6 for mortar systems) prevents proper mechanical bonding. Hangar slabs are often saturated with fuel, oils, and hydraulic fluids that penetrate deep into the concrete matrix. If not fully removed, these contaminants act as bond breakers, leading to delamination, softening under hydrocarbon exposure, and premature system failure. Substrates below ~3,500–5,000 psi compressive strength or with pull-off adhesion under ~250–350 psi are highly prone to coating separation under aircraft loads.
2. Fuel, Hydraulic Fluid & Chemical Exposure Degradation
Hangar floors are routinely exposed to Jet A, Avgas, Skydrol, and de-icing chemicals. Standard epoxy systems without novolac or chemical-resistant topcoats can soften, stain, or chemically degrade under repeated exposure. Continuous contact with hydrocarbons accelerates resin breakdown, reducing surface hardness and causing loss of structural integrity in high-use maintenance and fueling zones.
3. Moisture Vapour Transmission, Thermal Cycling & Slab Movement
Concrete slabs can transmit moisture vapour (~3–10+ lbs/1000 sq ft/24 hrs, ASTM F1869), creating pressure beneath coatings that leads to blistering, bubbling, and bond loss. Hangar environments also experience thermal cycling from large door openings, exterior temperature swings, and heated interiors. This expansion and contraction introduces stress within the slab and coating system, resulting in cracking, joint failure, or localized delamination if not properly addressed.
4. Improper System Design & Insufficient Build Thickness
Thin-film coatings below ~15–20 mils are not designed to withstand aircraft traffic or heavy equipment loads. Hangar environments typically require high-build epoxy systems at 2–4 mm, with heavy-duty zones needing epoxy mortar at 3–6 mm+ to handle point loads exceeding 200–300 psi. Systems lacking sufficient thickness, reinforcement, or chemical resistance fail prematurely, showing wear-through, impact damage, and localized breakdown in high-stress areas.
Long-term performance in aviation environments depends on aligning system design with aircraft loads, chemical exposure, and substrate conditions. When concrete is properly prepared, contaminants are eliminated, and systems are specified with appropriate chemistry and thickness, epoxy flooring maintains adhesion, resists fuel-related degradation, and performs reliably under continuous hangar operations.
Our Aviation & Hangar Epoxy Flooring Installation Process
Aviation flooring installations are engineered around aircraft load requirements, hydrocarbon exposure, and continuous mechanical traffic. Hangar slabs must support concentrated loads exceeding 200–300 psi, resist Jet A and Avgas fuel, and maintain adhesion under thermal cycling and moisture vapour transmission. Proper execution ensures the flooring system delivers long-term durability, chemical resistance, and structural performance in active aviation environments.
Step 1: Site Evaluation & System Planning
We assess hangar operations, aircraft types, and traffic patterns, including ground support equipment and maintenance zones. The concrete substrate is evaluated for compressive strength (typically ≥3,500–5,000 psi), surface integrity, and hydrocarbon contamination. Moisture vapour transmission is tested using ASTM F2170 (in-situ RH) or ASTM F1869 (calcium chloride). Fuel exposure levels, load requirements, and operational constraints determine system selection and build thickness—typically 2–4 mm for high-build epoxy or 3–6 mm+ for heavy-duty epoxy mortar systems.
Step 2: Surface Preparation & Contamination Removal
Concrete is mechanically prepared using industrial diamond grinding or shot blasting to achieve CSP 3–5 for coatings and CSP 4–6 for mortar systems. Fuel, oil, and hydraulic fluid contamination is removed through mechanical and chemical degreasing processes to eliminate bond-breaking residues. Existing coatings, laitance, and weak surface layers are fully removed. Cracks, spalls, and joint damage are repaired using epoxy patching compounds or mortar systems, resulting in a structurally sound substrate capable of achieving pull-off adhesion values of ≥250–350 psi.
Step 3: System Installation
A moisture-tolerant epoxy primer is applied at approximately 6–12 mils to establish adhesion and mitigate vapour-related risks. High-build 100% solids epoxy systems are installed at 2–4 mm for general hangar areas, while epoxy mortar or novolac systems (3–6 mm+) are used in zones exposed to heavy aircraft loads or fuel contact. Broadcast aggregates such as quartz or aluminum oxide may be incorporated to enhance abrasion resistance and slip performance. Protective topcoats, including polyurethane or polyaspartic, are applied at 6–12 mils to improve chemical resistance, UV stability, and long-term durability.
Step 4: Curing, Inspection & Return to Operation
Curing is controlled based on system chemistry and site conditions to achieve full cross-linking and performance. Once cured, the flooring system is inspected for adhesion, uniform thickness, and surface continuity. High-stress areas—including joints, transitions, and fueling zones—are verified for integrity and resistance to load and chemical exposure. Where required, installations are phased to maintain operational continuity, allowing hangars to return to service with minimal disruption.
Successful aviation flooring installations depend on aligning substrate preparation, system chemistry, and build thickness with real-world hangar conditions. When each phase is executed to specification, the result is a seamless, load-bearing surface that resists fuel exposure, mechanical wear, and environmental stress while supporting reliable day-to-day operations.
