ESD Flooring

IEC 61340-5-1 compliant conductive flooring for electronics manufacturing, pharmaceutical cleanrooms, semiconductor handling.

What is ESD Flooring?

Electrostatic discharge flooring is a specification-grade conductive or dissipative floor system engineered to control the accumulation and release of static electricity within environments where unmanaged charge poses a risk to sensitive equipment, personnel, or process integrity. Compliant with IEC 61340-5-1, these systems establish defined electrical resistance pathways — typically between 1 × 10⁴ Ω and 1 × 10⁹ Ω — that safely channel electrostatic potential to earth before it reaches a threshold capable of damaging components or igniting volatile atmospheres.

ESD flooring is specified by facility engineers, cleanroom consultants, pharmaceutical validation teams, and semiconductor handling specialists wherever static control is a process-critical requirement rather than an aesthetic preference. It is not a commodity coating — it is a precision system with measurable, auditable electrical performance.

When to Specify ESD Flooring

Electronics assembly and semiconductor handling facilities represent the primary specification environment: a single uncontrolled discharge event can destroy an integrated circuit valued at multiples of the floor surface beneath it. Pharmaceutical cleanrooms, where sensitive API formulations and packaging lines operate in controlled environments, require dissipative flooring to maintain both product integrity and regulatory compliance. Defence electronics workshops, data centre raised-floor zones, hospital operating theatres with electronic life-critical equipment, and petrochemical facilities with explosive atmosphere classifications are all sectors in which ESD specification is non-negotiable.

Any project operating under ATEX zoning, ISO 14644 cleanroom classification, or internal EHS static control programmes will benefit from a formally specified IEC 61340-5-1 compliant floor system installed and signed off by trained specialists.

Methodology — The Epoxy GH Specialist Approach

Specification Review & Resistance Zone Mapping. Our specialists receive the project’s ESD control programme, reviewing target resistance ranges, grounding conductor layouts, and regulatory framework (IEC 61340-5-1, ANSI/ESD S20.20, or facility-specific standard) before any site visit is scheduled.
Site Survey & Substrate Assessment. A structured substrate evaluation records slab moisture content, existing coating condition, surface profile, and the locations of structural grounding points. Moisture readings exceeding 75% RH trigger a remediation protocol before any ESD system is applied.
Surface Preparation to CSP 3–5. Diamond-head shot-blast or scarification equipment prepares the substrate to the required Concrete Surface Profile, removing laitance, contamination, and surface irregularities that would compromise adhesion and electrical continuity.
Conductive Primer & Copper Earthing Grid Installation. A two-component conductive epoxy primer is applied at specification thickness, integrating a copper tape earthing grid bonded to the facility’s main protective earth. Grid spacing and conductor continuity are verified by resistance measurement before topcoat proceeds.
Topcoat Application & IEC 61340-5-1 Validation Testing. The specification-grade ESD topcoat is applied in controlled lift thicknesses. On cure, resistance-to-ground readings are taken at a minimum grid of measuring points across the installed surface. Results are documented in a formal test record and issued as the project handover certificate.

Materials & Standards

ESD conductive epoxy primer — two-component, volume resistivity < 10⁴ Ω·cm
Copper earthing tape grid — specification-grade, bonded to facility protective earth
ESD dissipative topcoat — two-component polyurethane-modified epoxy, 2–3 mm system thickness
IEC 61340-5-1 — primary electrical performance standard for ESD flooring systems
ANSI/ESD S20.20 — supplementary standard referenced for electronics manufacturing environments
ISO 14644-1 — cleanroom classification compatibility where pharmaceutical or semiconductor sectors require dual compliance

Outcomes & Guarantees

A correctly installed Epoxy GH ESD system delivers a measurably stable, compliant electrical resistance floor that supports your static control programme from day one of occupation. Performance is documented, not assumed.

Warranty Tier	Coverage Period	Scope

Facilities specifying ESD flooring frequently require complementary systems across the same floor plate. Our specialists also deliver Cleanroom Flooring, Chemical-Resistant Flooring, and Heavy-Duty Industrial Flooring — each installed to the same specification-grade rigour that defines 45 years of Epoxy GH practice.
