Yes, epoxy flooring is food safe when using systems specifically formulated and certified for food contact. Food-grade epoxy systems comply with EU Regulation 10/2011, FDA CFR 175.300, and UK food contact regulations. These certified systems contain no toxic components, resist bacterial growth, and withstand aggressive cleaning regimes required in food processing environments.
Food Safety Certifications
Food-safe epoxy flooring requires specific certifications confirming compliance with stringent regulations. Not all epoxy systems meet these standards—only those formulated without harmful plasticisers, solvents, or heavy metals qualify for food industry use.
EU Regulation 10/2011
European food contact regulations demand comprehensive testing for migration of substances into food. Certified systems undergo testing at various temperatures and pH levels, simulating worst-case food contact scenarios. Migration limits typically restrict transfer to less than 10mg/dm² total, with specific limits for individual substances.
Testing covers four food simulants: aqueous foods (water), acidic foods (3% acetic acid), alcoholic foods (10% ethanol), and fatty foods (vegetable oil). Systems must pass all categories for full certification. Our food safe flooring installations exclusively use EU 10/2011 certified products.
FDA CFR 175.300
The US Food and Drug Administration's Code of Federal Regulations Title 21, Section 175.300 covers resinous and polymeric coatings for food contact surfaces. This standard focuses on extraction testing, measuring substances released when exposed to food-simulating solvents.
- Water extraction: 8% ethanol at 120°F for 24 hours
- Heptane extraction: For fatty food contact at 120°F for 2 hours
- Ethanol extraction: 50% ethanol at 120°F for 24 hours
- Maximum extractables: 0.5 milligrams per square inch
UK Food Contact Regulations
Post-Brexit UK regulations maintain EU standards while adding specific requirements for UKCA marking. The Food Standards Agency oversees compliance, requiring declaration of conformity documentation and Good Manufacturing Practice certification for flooring manufacturers.

HACCP Compliance Requirements
Hazard Analysis and Critical Control Points (HACCP) principles drive flooring specifications in food facilities. Floors represent critical control points for contamination prevention, requiring specific characteristics to support food safety programmes.
Seamless Surface Requirements
HACCP demands elimination of cracks, joints, and crevices where bacteria proliferate. Seamless epoxy systems create monolithic surfaces without harbourage points. Coved skirting eliminates floor/wall joints, extending seamless protection vertically. All penetrations require sealed terminations preventing moisture ingress.
Surface texture balances cleanability with slip resistance. Smooth finishes clean easily but lack grip when wet. Orange-peel textures provide slip resistance while remaining cleanable. Heavy textures trap contamination despite excellent slip resistance. HACCP-compliant systems achieve R11 slip resistance with cleanable profiles.
Chemical Resistance Standards
Food processing requires resistance to products, cleaning chemicals, and sanitisers. Daily exposure to sodium hypochlorite (200ppm), quaternary ammonium compounds, and peracetic acid demands appropriate chemical resistance. Steam cleaning at 140°C and caustic washing further stress flooring systems.
Our food processing flooring withstands this aggressive regime while maintaining appearance and performance. Polyurethane concrete systems excel, resisting thermal shock from -40°C freezer to 120°C steam cleaning transitions.
Microbial Resistance
Food-safe flooring must resist microbial growth without relying on antimicrobial additives that may leach. Dense, non-porous surfaces prevent bacterial penetration. pH-neutral systems avoid creating environments favouring specific organisms. Silver-ion or triclosan additives aren't permitted in food contact applications.
| HACCP Requirement | Epoxy Solution | Verification Method | Frequency |
|---|---|---|---|
| Impervious surface | Seamless application | Visual inspection | Daily |
| Cleanable texture | Orange-peel finish | ATP testing | Weekly |
| Chemical resistance | PU concrete system | Surface assessment | Monthly |
| No harbourage | Coved skirting | Microbiological swabs | Monthly |
| Thermal tolerance | 9mm thickness | Integrity checks | Quarterly |

Beyond basic food safety compliance, epoxy flooring provides hygiene advantages supporting operational excellence in food facilities. These benefits reduce contamination risks while simplifying sanitation procedures.
Seamless Monolithic Surface
Traditional tiled floors contain thousands of grout joints harbouring bacteria despite regular cleaning. Research shows grout lines contain 10,000 times more bacteria than adjacent tiles after standard cleaning. Seamless epoxy eliminates these contamination reservoirs entirely.
Monolithic surfaces extend up walls as integral coving, eliminating floor/wall joints where debris accumulates. Radius coving enables complete cleaning access, preventing build-up in corners. This seamless transition proves particularly valuable in wet processing areas where water management is critical.
Non-Porous Characteristics
Epoxy's non-porous nature prevents absorption of liquids, oils, and proteins that support microbial growth. Spilled products remain on surfaces for immediate cleaning rather than penetrating substrates. This characteristic proves essential when handling allergens, preventing cross-contamination between production runs.
Porosity testing using dye penetrants confirms complete surface sealing. Quality systems show zero penetration after 24-hour exposure to methylene blue solution. This impermeability extends flooring life by preventing substrate degradation from absorbed contaminants.
Easy Cleaning Protocols
- Reduced water usage: Smooth surfaces require 40% less water than textured alternatives
- Faster cleaning: 50% time reduction versus tiled surfaces
- Chemical efficiency: Lower detergent consumption due to easy soil release
- Verification simplicity: Visual cleanliness correlates with microbiological cleanliness
- Automated cleaning: Compatible with robotic scrubbers and CIP systems
Food-Safe System Selection
Different food environments demand specific flooring characteristics. Understanding these requirements ensures selection of appropriate systems delivering long-term performance.
Polyurethane Concrete Systems
Polyurethane concrete represents the gold standard for food processing flooring. These cement-urethane hybrids combine chemical resistance, thermal shock tolerance, and mechanical durability. The coefficient of thermal expansion matches concrete substrates, preventing delamination during temperature cycling.

Environment-Specific Solutions
Food facilities encompass diverse environments requiring tailored flooring solutions. Each area's unique demands influence system selection and installation details.
Wet Processing Areas
Meat, poultry, and seafood processing involve constant water exposure and aggressive cleaning. These areas require 9mm polyurethane concrete with broadcast aggregates achieving R12 slip resistance. Integrated drainage channels with epoxy-coated grating prevent standing water.
Falls to drains at 1:50 minimum ensure positive drainage without creating trip hazards. Coved skirting extends 150mm minimum up walls, sealed to wall finishes. Penetrations for equipment receive puddle flanges and flexible sealants accommodating movement.
Dry Processing Areas
Bakeries, confectionery, and dry goods packaging require smooth, easily cleaned surfaces. 3mm self-levelling epoxy provides adequate durability with superior aesthetics. Matt finishes reduce glare under bright lighting while maintaining cleanability.
Static-dissipative formulations prevent dust attraction in flour handling areas. These systems ground personnel and equipment, preventing static discharge that attracts particles. Conductivity ranges from 10⁶ to 10⁸ ohms meet both safety and cleanliness requirements.
Cold Storage Facilities
Freezers and chillers demand flexibility accommodating thermal movement. Standard epoxy becomes brittle below 5°C, cracking under thermal stress. Flexible polyurethane or modified epoxy systems maintain elasticity at -40°C.
- Blast freezers: Thermal shock-resistant systems for rapid temperature changes
- Cold stores: Flexible systems accommodating substrate movement
- Loading docks: Transition zones requiring extreme temperature tolerance
- Ante-rooms: Condensation-resistant surfaces preventing slip hazards
