What is Infrastructure for the Food Industry?
The infrastructure of a food and beverage processing plant is a critical environment that must be designed, built, and maintained under the principle of food safety. It's not just about structural resistance, but about the ability of surfaces and systems to prevent the proliferation of pathogens (such as Listeria monocytogenes, Salmonella y E. coli), withstand aggressive chemical cleaning regimens, and resist severe thermal shocks.
Key components of adequate food infrastructure include:
- High-performance flooring: Monolithic, non-porous systems, without exposed joints, typically made of cementitious urethane or high-solids epoxies.
- Sanitary coves: Concave transitions between floor and wall that eliminate 90-degree angles where dirt accumulates.
- Drains and sanitary installations: AISI 304 or 316 stainless steel channels with correct slopes to prevent water stagnation.
- Aseptic walls and ceilings: Washable coatings, resistant to moisture and sanitizing agents based on chlorine, quaternary ammonium, or peracetic acid.
- Sanitary electromechanical installations: Food-grade stainless steel piping (OD tubing) welded using an orbital process and watertight electrical systems (NEMA 4X / IP69K).
When is maintenance intervention needed?
A plant or maintenance manager should schedule corrective or preventive intervention immediately upon detecting the following operational signs:
- Peeling paint or previous coating: Any flaking is a potential source of physical contamination in the final product.
- Cracks and potholes in concrete: Fissures accumulate moisture, organic matter, and bacteria that cannot be eliminated with the standard sanitization process.
- Water stagnation on floors: Deficient slopes that create puddles, violating food safety audits.
- Filtration in control joints: Damaged expansion joints or detached sealant that allow water to pass into the subsoil.
- Corrosion on supports and pipes: Presence of rust on structures near process lines.
- Non-conformities in audits: Direct observations from FSSC 22000, SQF, BRC, or COFEPRIS auditors regarding the condition of the facilities.
Problems SINE México solves
- Unscheduled plant shutdowns: We minimize downtime through logistical planning and the use of fast-curing materials.
- Risk of cross-contamination: We eliminate bacterial infection foci by installing monolithic and antibacterial surfaces.
- Sanctions and closures: We ensure your plant passes COFEPRIS, FDA inspections, and international certifications.
- Workplace slip hazards: We design customized non-slip textures for wet areas or those with grease and oil, complying with NOM-001-STPS.
- Structural deterioration due to chemical attack: We protect concrete against organic acids (lactic, citric, acetic) that rapidly destroy Portland cement.
Benefits for your plant
- Guaranteed regulatory compliance: Facilitates obtaining and maintaining certifications such as FSSC 22000, SQF, HACCP, and Distintivo H.
- Reduction of waste and market withdrawals (Recalls): Drastically reduces the risk of microbiological contamination in the manufacturing environment.
- Ease and speed of cleaning: Smooth but non-slip surfaces reduce cleaning cycle times (CIP/COP) and water and chemical consumption.
- Extreme durability (Return on Investment): A cementitious urethane system correctly specified by SINE México has a useful life of over 10 years, reducing the total cost of ownership (TCO).
Applications by process area
| Plant Area | Exposure Type | Recommended Solution | Suggested Thickness |
|---|---|---|---|
| Wet Processing (Dairy, Meat) | Thermal shock, acids, high-pressure washing | Self-Leveling / Trowel Applied Cementitious Urethane | 6.0 mm to 9.0 mm |
| Warehouses and Distribution Centers (Forklift Traffic) | Abrasive impact, heavy traffic, minor spills | 100% Solids Epoxy with quartz sand | 2.0 mm to 3.0 mm |
| Cold Rooms and Freezers | Continuous sub-zero temperatures (-20°C to -40°C) | Methyl Methacrylate (MMA) or Cementitious Urethane | 4.0 mm to 6.0 mm |
| Dry Packing Areas | Pedestrian and pallet jack traffic, dust | Low Odor Epoxy Self-Leveling | 1.5 mm to 2.0 mm |
| Industrial Kitchens / Laboratories | Greases, reagents, constant cleaning | Novolac Epoxy or Quartz Multilayer System | 3.0 mm |
Specification materials and technologies
At SINE México, we don't improvise. We select materials formulated by global leaders in the construction chemical industry:
- Cementitious Urethanes (SikaScreed, PurCem, MasterTop): Ideal for resisting extreme thermal shocks from -40°C to 120°C. Withstand live steam cleaning.
- Novolac Epoxy Resins (Sherwin-Williams, Cover): Designed for areas with high concentrations of aggressive chemical agents and concentrated acids.
- Methyl Methacrylate (MMA): Ultra-fast curing resins (reach maximum mechanical strength in less than 2 hours), ideal for express repairs in freezer rooms without shutting down evaporators.
- Wall Paints and Coatings: Two-component water-based polyurethane enamels with silver ion additives that actively inhibit bacterial growth on walls and ceilings.
Applicable Regulations and Standards
Our projects are executed in strict adherence to national and international regulatory frameworks:
- NOM-251-SSA1-2009: Hygiene practices for the processing of food, beverages, or dietary supplements in Mexico.
- HACCP (Hazard Analysis Critical Control Point): Facility design focused on eliminating critical points of physical and biological contamination.
- FDA (Food and Drug Administration) & USDA: Regulations for materials suitable for indirect contact with food.
- ANSI/NSF Standard 51: Certification of materials for food industry equipment and surfaces.
- NOM-001-STPS-2008: Safety requirements for buildings, premises, facilities, and work areas (conditions of floors and ramps).
Our work process (SINE México)
- Technical Diagnosis: We visit your plant to evaluate the substrate's condition (ASTM F2170 relative humidity tests, concrete compression strength with a sclerometer, and contaminant detection).
- Engineering Proposal: We design the optimal solution, specifying materials, thicknesses, textures, and a detailed work schedule.
- Surface Preparation: Critical phase. We use shot blasting and grinding equipment with integrated aspiration (HEPA) to prevent dust suspension in production areas.
- System Application: Installation of primers, base mortars, seal coats, sanitary coves, and finishes by certified technical personnel.
- Quality Control: Verification of wet/dry film thickness, adhesion (Pull-Off test ASTM D4541), and texture continuity.
- Delivery and Release: Delivery of a technical dossier including technical data sheets, safety data sheets, material quality certificates, and a written warranty policy.
Common errors when hiring / installing
- Omitting concrete moisture testing: Applying an epoxy to concrete with more than 4% moisture causes blistering (osmosis) and premature detachment. At SINE México, we always measure moisture and apply vapor barriers if necessary.
- Poor surface preparation: The use of muriatic acid to "open pores" weakens the concrete structure and leaves residual salts. Always demand mechanical preparation (CSP).
- Use of conventional epoxies in thermal shock areas: Standard epoxy fractures when exposed to hot water due to the difference in expansion with concrete. Cementitious urethane should be used.
- Failure to consider ventilation: Applying solvent-based products in active plants can contaminate entire production batches with odor. We use 100% solids, solvent-free products.
SINE Mexico Warranty
All our projects in the food industry are backed by a written warranty of up to 5 years (depending on the specified system). We have direct support from the manufacturers of the most important brands in the market, which ensures that both SINE's skilled labor and the materials used comply with the highest standard of industrial performance.
