What is Maintenance for the Automotive Industry?
Maintenance and infrastructure adaptation for the automotive industry comprises a set of engineering services, civil works, electromechanical assemblies, and the application of high-performance coatings designed to withstand the rigorous operating conditions of assembly plants (OEMs), component manufacturers Tier 1 y Tier 2.
This sector demands millimeter precision and absolute reliability, as a single minute of downtime on an automotive assembly line can represent losses of thousands of dollars. Key components of this service include:
- High-performance industrial flooring: Epoxy, polyurethane, and cementitious urethane systems to withstand heavy traffic and chemical spills.
- Specialized civil works: Deep foundations, pits for stamping presses, pipe trenches, and bases for welding robots.
- Electromechanical installations: Compressed air networks, cooling systems (chillers), electrical substations, and power distribution.
- Metal structures and plate work: Mezzanines, dynamic storage racks, conveyors, and safety protections (guards).
When is it needed?
A maintenance or plant manager should schedule these specialized services upon detecting the following operational signals:
- Concrete spalling or potholes in traffic aisles: Constant forklift traffic with rigid polyurethane wheels destroys expansion joints and exposed concrete.
- Production line reconfiguration: Introduction of new vehicle platforms requiring relocation of machinery, robots, and power services.
- Cutting fluid (soluble) leaks into the subsoil: Cracks in trenches or machining pits that violate SEMARNAT environmental regulations.
- Voltage drops or overheating in electrical panels: Sign of saturation in the electrical distribution network due to increased installed load.
- Non-conformities in client audits: Observations of order, cleanliness, safety, or lack of area delimitation under the 5S methodology.
Problems it solves
- Unscheduled line shutdowns: Avoid catastrophic infrastructure failures that halt continuous assembly flow.
- Risks of workplace accidents: Correct slippery floors, lack of internal road signage, and deficiencies in grounding systems.
- Component contamination: Control the generation of concrete dust (fine particle detachment) that damages electronic components and painting processes.
- Fines for regulatory non-compliance: Prevent STPS and PROFEPA sanctions through safe installations and containment of hazardous waste.
Benefits for your plant
- Operational continuity guarantee: Planned execution that ensures the plant starts on time after a scheduled downtime (shut down).
- Increased asset value: Extends the useful life of industrial buildings, press pits, and concrete pavements.
- Compliance with IATF 16949 standards: Facilitates approval of global client audits by maintaining infrastructure in optimal conditions.
- Measurable Return on Investment (ROI): A 1% reduction in line stoppages due to infrastructure failures pays for the annual preventive maintenance investment.

Specified Materials and Technologies
At SINE México, we don't improvise; we select materials from world-leading brands under strict engineering criteria:
- Epoxy and Novolac Systems (Sherwin-Williams / Sika / Cover): Ideal for chemical and cutting fluid storage areas due to their excellent resistance to acid attack and solvents.
- Cementitious Urethanes (BASF MasterBuilders / Fosroc): Designed for areas subject to high-pressure steam cleaning, hot liquid spills, and continuous heavy traffic.
- Fast Curing Systems (MMA - Methyl Methacrylate): Allow opening to heavy traffic in just 2 hours after application, ideal for extremely short maintenance windows.
- High-Strength Chemical Anchors (Hilti): For secure fastening of welding robots and heavy machinery subjected to dynamic stresses.
Applicable Regulations and Standards
Our projects are executed in strict compliance with national and international regulations:
- IATF 16949 & ISO 9001: Quality management systems for the automotive sector.
- NOM-001-SEDE-2012: Electrical installations (utilization) to ensure fire and discharge safety.
- NOM-005-STPS-1998: Safety and hygiene conditions in workplaces for handling chemical substances.
- AWS D1.1 (American Welding Society): Structural welding code for steel, ensuring the integrity of mezzanines and supports.
- ACI 302.1R (American Concrete Institute): Guide for concrete floor and slab placement and finishing.
Our work process (SINE)
- On-Site Technical Diagnosis: We evaluate substrate conditions, mechanical loads, chemical exposure, and available time windows at no cost to you.
- Detailed Engineering and Proposal: We present a justified technical solution with material data sheets, application methodology, and work schedule.
- Mechanical Substrate Preparation: Critical phase where we use diamond planetary grinders, shotblasters, or scarifiers to ensure an anchor profile from CSP 3 to CSP 9 according to coating specification.
- Specialized Application: Execution by certified technicians using precision dosing equipment and controlling environmental variables (relative humidity, dew point, and substrate temperature).
- Quality Control: Adhesion pull-off tests (pull-off test ASTM D4541), dry film thickness measurement, and dielectric continuity tests.
- Delivery and Quality Dossier: Delivery of the work along with technical documentation, material quality certificates, test reports, and a written warranty policy.
Common mistakes when hiring non-specialized contractors
- Omitting mechanical floor preparation: Applying coatings on smooth or oil-contaminated concrete causes delamination in a few months.
- Underestimating dynamic loads: Designing concrete slabs or structures without calculating the torsion and vibration moments of industrial robots.
- Using uncertified labor: Causes work stoppages by the plant's safety commissions due to risky practices.
- Not respecting curing times: Forcing the delivery of an epoxy floor before it reaches its full chemical cure drastically reduces its lifespan.
Factors that determine project cost
The cost of an automotive maintenance project varies according to specific plant factors:
- Condition of the current substrate: The level of oil contamination (which requires deep chemical decontamination) or structural damage to the concrete.
- Thickness and type of system: Self-leveling systems from 3 mm to 6 mm vary in material consumption per square meter.
- Logistics and execution schedules: Work performed during scheduled weekend or holiday shutdowns incurs differentiated operating costs.
- Total area to be intervened: Economies of scale apply to high-volume square meter projects.

Frequently Asked Questions
How do you guarantee not to interrupt the production line during the work?
We plan critical interventions during scheduled shutdowns, weekends, or night shifts. We coordinate 24-hour continuous work crews using Critical Path Methodology (CPM) to ensure delivery before the start of the shift, minimizing the risk of unplanned stoppages on assembly lines.
What type of coating do you recommend for machining and assembly areas?
For machining areas exposed to cutting fluids and oils, we recommend high chemical resistance novolac epoxy systems. In assembly areas and heavy forklift traffic with polyurethane wheels, we apply 6 mm thick cementitious urethanes or high impact resistance self-leveling systems ASTM D2794.
Do you have safety certifications to work in automotive plants?
Yes, all our operational personnel have valid DC-3 labor skills certificates for work at heights, confined spaces, electrical safety, and cutting and welding. We work under OSHA guidelines and applicable STPS regulations to meet the contractor requirements of the most demanding automakers.
What quality standards govern your automotive maintenance processes?
We align our processes with the requirements of the IATF 16949 automotive quality management standard, ensuring material traceability, process control, and quality audits. In civil works and structures, we are governed by ACI and AWS regulations, and in electrical installations by NOM-001-SEDE.
