Sol conducteur classé ESD avec résistance de surface mesurée.

The Challenge

In semiconductor cleanrooms, pharmaceutical fill-finish lines, and Tier-3 and above data centres, the floor beneath the equipment is not a passive surface — it is an active component of the facility’s safety and compliance architecture. Electrostatic discharge events that register as imperceptible to a technician can destroy microelectronics, corrupt sensitive batch records, or ignite solvent-laden atmospheres in an instant. The consequence is not aesthetic; it is operational shutdown, product recall, or regulatory sanction.

Ghana’s industrial and technology infrastructure has matured significantly since the early 2000s. Multinational pharmaceutical manufacturers, regional data centre operators, and precision electronics assembly facilities now commission buildings in Tema Industrial, Airport City, and the Greater Accra corridor that demand surface-resistance values measured in ohms — not merely floors that “look clean.” Specifying the wrong system, or installing the correct system without rigorous continuity testing, creates liability that no facility manager can absorb.

The procurement challenge is compounded by a thin local market for genuinely specification-grade ESD systems. Many suppliers offer standard epoxy with a conductive filler added as an afterthought. The surface-resistance result — which must fall within the ANSI/ESD S20.20 or IEC 61340 bands — is never independently verified at handover. Floors GH was established in 1972 to close precisely this gap: the distance between a floor that appears compliant and one that demonstrably is.

The Floors GH Solution

Floors GH applies a four-stage ESD flooring methodology developed across 54 years of premium industrial practice. The process opens with sub-floor moisture assessment per ASTM F2170, using in-situ relative humidity probes to detect moisture-vapour emission at depth — not merely surface damp that evaporates before inspection. No primer is applied until the substrate passes this threshold. This single discipline eliminates the delamination and resistance-drift failures that compromise most post-handover ESD complaints.

Surface preparation is conducted to ICRI Concrete Surface Profile standards, with profile selection matched to the coating system’s specified mil thickness and pot life. The ESD system itself is a multi-layer assembly: a conductive primer bonded to a continuous copper ground-strap grid, a static-dissipative mid-coat, and a topcoat formulated to the client’s specified surface-resistance band — typically 1×10⁵ to 1×10⁹ Ω for static-dissipative, or 1×10⁴ to 1×10⁵ Ω for conductive classifications.

Multi-stage QC sign-off is conducted at substrate, primer, mid-coat, and finish milestones. Final handover includes a ground-strap continuity test and a full surface-resistance mapping document — point-tested across the installed area in a grid pattern — delivered as a physical and digital record. This is the written guarantee that Tier-1 institutional clients specify, and that Floors GH has delivered since its founding year.

Material + System Specification

Typical Project Profile

A standard ESD flooring commission spans 500 to 4,000 m², with a programme of 10 to 21 working days from substrate acceptance to final resistance sign-off. Sectors served include pharmaceutical manufacturing facilities and fill-finish suites, Tier-3 and Tier-4 data centres, electronics assembly and semiconductor-adjacent cleanrooms, and precision laboratory environments. Free on-site survey and same-day response to technical enquiries are standard.
