What is León in the Industrial Context?
León, Guanajuato, is the economic engine of the Bajío region, consolidated as a diversified industrial hub that goes beyond its historic leather-footwear chain. Today, the León-Silao region hosts advanced manufacturing, automotive (auto parts and assembly), logistics, packaging, and food clusters.
To maintain competitiveness and comply with global audits (IATF 16949, SQF, HACCP), industrial plants in León require high-performance physical infrastructure. SINE México offers surface engineering solutions, preventive/corrective maintenance, and industrial construction designed to withstand the most severe operating conditions in the region.
When is industrial maintenance and coating needed?
A plant or maintenance manager in León should schedule an intervention when they detect the following critical signs in their facilities:
- Concrete spalling and patching: Presence of potholes, structural cracks, or dust spalling (abrasion wear) in forklift traffic aisles.
- Visible chemical attack: Floors corroded by spills of acids, salts, or tanning agents in wet process areas.
- Loss of dielectric or conductive properties: Need to upgrade electronic assembly areas to ESD (Electrostatic Discharge) systems.
- Observations in quality audits: COFEPRIS, FDA, or automotive client observations due to porous floors, lack of sanitary coves, or worn safety signage.
- Leaks and drips in roofs: Humidity that puts precision machinery, electrical panels, or stored raw material at risk.
Problems SINE México solves
- Unscheduled plant shutdowns: We restore floors and structures using fast-curing technologies to intervene during weekend maintenance windows.
- Workplace risks (STPS Fines): We eliminate slippery surfaces by applying systems with an anti-slip anchor profile and clear demarcation of pedestrian and forklift areas.
- Non-conformities in audits: We install food and pharmaceutical grade coatings with integral sanitary coves that prevent the proliferation of fungi and bacteria.
- Structural degradation: We protect concrete and steel structures against carbonation and severe industrial corrosion.
Benefits for your plant in León
- Extended asset lifespan: Up to a 300% increase in abrasion resistance of existing concrete.
- Reduced forklift maintenance costs: Level surfaces without damaged joints reduce wear on wheels, suspensions, and batteries of loading equipment.
- Full regulatory compliance: Ease of cleaning that ensures approval in national and international audits.
- Accelerated Return on Investment (ROI): By minimizing cleaning times and eliminating constant emergency repair shutdowns.

Specification materials and technologies
We do not improvise with generic materials. At SINE México, we specify and apply technologies from leading global brands under strict technical data sheets:
- Sika (SikaFloor / PurCem): Ideal for cementitious urethanes and fast-repair mortars in the food and automotive industry of the Bajío region.
- Sherwin-Williams (General Polymers): Decorative and high-performance epoxy systems for hangars, warehouses, and clean production areas.
- BASF / Master Builders Solutions: Polyurethane resins and quartz hardeners for floors subjected to extreme heavy traffic.
- ESD Systems (Dissipative/Conductive): Formulated with carbon fibers to safely drain static to ground in electronic assembly lines.
Applicable Regulations and Standards
Our projects in León are executed under strict compliance with national and international regulatory frameworks:
- NOM-026-STPS-2008: Safety and hygiene colors and signs for delimiting work areas.
- FDA (Food and Drug Administration) and USDA: Materials approved for indirect food contact, free of VOCs (Volatile Organic Compounds).
- HACCP: Design of hygienic systems with sanitary coves to prevent accumulation of contaminants in corners.
- ASTM C779: Evaluation of abrasion resistance of concrete surfaces.
- ACI 302.1R: Guide for the placement and finishing of industrial concrete floors.
Our work process in León
- On-Site Technical Diagnosis: We evaluate concrete hardness (sclerometry), humidity levels (calcium chloride test), and hydrocarbon contamination at your plant in León or Silao at no cost.
- Engineering Proposal: We present the specification of the appropriate system along with the surface preparation methodology and detailed work plan.
- Mechanical Surface Preparation: Critical phase for success. We perform diamond grinding or shotblasting to obtain the anchor profile (CSP 3 to CSP 6) according to ICRI (International Concrete Repair Institute) standards.
- System Application: Installation of vapor barrier primers (if humidity is present), base coats, aggregate broadcast (if anti-slip is required), and finish sealers under controlled temperature and humidity conditions.
- Quality Control: Measurement of wet and dry film thickness, adhesion tests (Pull-Off ASTM D4541), and dielectric continuity verification if applicable.
- Delivery and Warranty Policy: Delivery of the clean area, ready to operate, accompanied by technical documentation and a written warranty policy.
Common mistakes when hiring or installing (And how we avoid them)
- Omitting mechanical preparation: Applying resins on smooth concrete or concrete contaminated with oil guarantees floor detachment within a few months. At SINE, we always mechanically prepare the substrate.
- Ignoring ground moisture: Osmotic pressure destroys epoxy floors if a vapor barrier is not installed beforehand. We measure humidity before applying any resin.
- Specifying by price and not by use: Applying a thin epoxy in an area with 5-ton forklift traffic causes immediate fractures. We design the appropriate thickness for the actual load of your operation.
Factors determining cost
The cost of an industrial maintenance or flooring project in León varies according to the following physical site conditions:
- Current substrate condition: Amount of cracks, potholes, or oil contamination requiring prior repair.
- System thickness: The greater the thickness (measured in millimeters or microns), the greater the consumption of high-performance resins.
- Logistics and schedules: Work performed during night shifts, weekends, or holiday shutdowns to avoid affecting production.
- Total area (m²): The larger the surface area, the more we optimize fixed costs for mobilization and surface preparation.
SINE Mexico Warranty
All our projects in León, Guanajuato, come with a written warranty of up to 5 years (depending on the specified system). We have the direct support of the world's leading resin manufacturers, which ensures that both the material and the workmanship meet the highest industry standards.
Frequently Asked Questions
Do you have immediate service coverage in León and Silao?
Yes, at SINE México, we have infrastructure and operational crews with direct coverage in León, Silao (Puerto Interior), San Francisco del Rincón, and Lagos de Moreno. This allows us to conduct free technical diagnostic visits within 24 hours and schedule executions during weekend or holiday technical shutdowns to avoid operational losses.
What type of flooring do you recommend for tannery plants in León?
For the tanning and leather finishing sector, we recommend cementitious urethane systems (such as SikaScreed or PurCem) with an aliphatic polyurethane finish or Novolac epoxy systems. These materials resist severe chemical attack from acids, salts, chromium, and organic solvents, in addition to withstanding heavy forklift traffic and constant high-pressure water washing.
Do you comply with safety requirements for entering industrial parks like Puerto Interior?
Absolutely. All our personnel have active REPSE registration, IMSS (valid SUA), DC-3 safety certifications (work at heights, confined spaces, chemical handling), and approved personal protective equipment (PPE). We comply 100% with the strictest contractor filters of automotive assemblers and industrial parks in the Bajío region.
How much curing time is required before releasing the floor to heavy traffic?
It depends on the selected technology. A standard epoxy system requires 24 hours for pedestrian traffic and 72 hours for heavy forklift traffic. However, for critical plant shutdowns in León, we apply fast-curing systems such as accelerated-curing Polyurethane Cement or Polyaspartics, which allow full opening to heavy traffic in just 12 to 24 hours.
