Static Dissipative (ESD) Flooring
Conductive and static-dissipative epoxy floors to ANSI/ESD S20.20 and IEC 61340 for electronics, pharmaceutical and sensitive-equipment facilities across Accra, Spintex and Kumasi — laid to ICRI CSP over a moisture-tested slab (ASTM F2170/F1869), the discipline that prevents the
Static-dissipative (ESD) flooring is a conductive resin floor system that gives electrostatic charge a controlled, earthed path to ground before it can reach sensitive components, equipment or personnel. It is specified, installed and verified to ANSI/ESD S20.20 and the IEC 61340 series, holding floor resistance within the defined dissipative band. In Ghana’s humidity its success is decided beneath the resin — by slab moisture testing and substrate preparation. Epoxy Flooring Ghana has installed ESD floors across Accra, Spintex and Kumasi since 1981.
Why Most Epoxy Floors Fail in Ghana — and How We Prevent It
The epoxy itself rarely fails; the slab beneath it does. In Ghana’s persistent 81–83% relative humidity, moisture vapour rising through a concrete slab builds osmotic and hydrostatic pressure under the coating and lifts it — and on an ESD floor a single disbonded area breaks the conductive path to earth and silently voids the static-control compliance the facility was certified on. It is the single most common epoxy failure in the country, and almost every failed floor skipped one step: slab moisture testing before the resin went down.
We treat moisture as the primary engineering control. Before a drop of resin is mixed we test in-situ relative humidity to ASTM F2170 and moisture-vapour emission to ASTM F1869, and prime to the reading. That discipline — not the conductive resin alone — is what keeps an ESD floor bonded and compliant in this climate.
ESD Epoxy Systems We Install in Accra & Kumasi
Static-Dissipative Epoxy
A dissipative-band resin floor for electronics assembly, server rooms and general ESD-protected areas where a controlled discharge path to earth is the requirement.
Conductive Epoxy
A lower-resistance conductive system for the most demanding semiconductor, pharmaceutical and explosive-atmosphere environments, specified to the tighter end of the ANSI/ESD S20.20 band.
ESD Self-Levelling Epoxy
A seamless, flow-applied conductive floor for cleanroom and pharmaceutical suites where a smooth, jointless, easily decontaminated plane is required alongside static control.
Copper-Grid Earthing System
The bonded copper earthing grid beneath the conductive build, installed to the IEC 61340 / ANSI/ESD S20.20 earthing-continuity requirement and tied into the facility earth.
The Moisture-Testing & ESD-Standard Doctrine
| Test / Standard | What it measures | Why it decides the floor |
|---|---|---|
| ASTM F2170 | In-situ relative humidity (probes at 40% slab depth) | The dominant pre-install moisture test; the resin system and primer are chosen to this reading |
| ASTM F1869 | Calcium-chloride moisture-vapour emission rate | Surface vapour load; flags slabs that need a vapour-suppression primer |
| ANSI/ESD S20.20 | ESD-control programme and floor resistance limits | The governing ESD standard; sets the resistance band the floor must hold and is verified to |
| IEC 61340 | ESD measurement and classification | Supports S20.20 with the test and earthing-continuity methods used to verify the floor |
| ICRI CSP | Concrete surface profile after preparation | The mechanical key the resin bonds to — concrete uses ICRI CSP, not the steel-only ISO 8501 |
How We Install an ESD Floor
- Slab moisture & substrate testing — ASTM F2170 in-situ RH + ASTM F1869 MVER before anything else.
- Surface preparation — diamond grinding / shot-blasting to the specified ICRI CSP; laitance and contaminants removed.
- Earthing grid & conductive build — bonded copper earthing grid, conductive primer, ESD-grade resin and dissipative topcoat to the ANSI/ESD S20.20 target.
- Resistance testing & handover — point-to-point and resistance-to-ground readings logged against the S20.20 band, signed compliance report.
Comparing ESD Systems for Ghana’s Climate
| System | Best for | Resistance position | Moisture tolerance |
|---|---|---|---|
| Static-dissipative epoxy | Electronics assembly, server rooms | Mid dissipative band | High when slab is tested & primed |
| Conductive epoxy | Semiconductor, pharma, explosive-atmosphere | Lower-resistance / conductive | High when slab is tested & primed |
| ESD self-levelling epoxy | Cleanroom, pharmaceutical suites | Dissipative, seamless | High; seamless monolithic build |
| Copper-grid earthing | All ESD builds (sub-layer) | Earthing continuity | Bonded beneath conductive layers |
What Affects the Cost
- The conductive system and resistance target (dissipative vs conductive) and earthing-grid extent
- Slab condition and any moisture remediation or crack repair required
- Area (m²), access, and whether the facility stays operational during works
- Cleanroom-grade detailing, coving and chemical-resistant topcoat specified
Every quote follows a site survey and slab moisture test — no fixed rate is given before the slab is tested.

Frequently Asked Questions
What standard governs ESD flooring? ANSI/ESD S20.20 sets the ESD-control programme and the floor resistance limits, supported by the IEC 61340 series for measurement and classification. We specify, install and verify the floor to those standards — point-to-point and resistance-to-ground readings logged at handover.
Why do ESD epoxy floors fail in Ghana? Usually slab moisture, not the conductive system. In Ghana’s 81–83% humidity, trapped vapour under the resin builds osmotic and hydrostatic pressure and lifts it — breaking the conductive path to earth and voiding the ESD compliance. The fix is to test in-situ RH (ASTM F2170) and moisture-vapour emission (ASTM F1869) before installation and prime to the reading.
Where is ESD flooring required? Electronics and PCB assembly, semiconductor handling, pharmaceutical and cleanroom production, server and data rooms, and any environment where an electrostatic discharge could destroy components, void a batch or ignite a sensitive atmosphere — anywhere the design brief classifies static control.
How much does an ESD floor cost? It is quoted on survey — cost varies with the conductive system, earthing grid, resistance target, slab condition and moisture remediation, area and access. We never give a fixed rate before testing the slab; request a site survey.
