Why a Material Reference Matters
Architects, interior designers, and facilities managers commissioning specification-grade flooring across Tier-1 institutional projects work against tight specification windows in which the floor system must be confirmed before adjacent trades — joinery, services, terminations — can be programmed to certainty. This reference is the consolidated guide to the eight specification-grade flooring systems Floors GH installs, with the sector matches, performance characteristics, and specification-stage decision points each system requires. It is intended for the design and facilities role specifically — distilling fifty-four years of Floors GH practice into the comparative reference a specifier should be able to consult when selecting a system for a Tier-1 commission.
System 1 — Marble and Premium Stone Installation
Specification-grade marble and natural stone — Carrara, Calacatta, Turkish Emperador, and select African marbles — book-matched and installed to architectural drawing for institutional lobbies, embassy reception floors, premier hospitality entrance courts, ministerial residences. Visual register: mineral permanence. Performance register: low-maintenance polishable surface across decades. Specification decision point: substrate moisture verification per ASTM F2170 governs feasibility — moisture above threshold compromises bond integrity within 18 months without remediation.
System 2 — Polished Concrete
Multi-stage diamond-polished structural concrete delivering specified reflectivity from satin-matte to mirror finish. Specified across museum galleries, corporate headquarters lobbies, premium retail flagships, institutional banking halls. Visual register: composed contemporary. Performance register: lowest whole-life maintenance among premium systems. Specification decision point: aggregate exposure level governs visual outcome — agreed at specification stage, not site stage.
System 3 — Specification-Grade Industrial Epoxy
Multi-layer chemically resistant epoxy systems for pharmaceutical manufacturing, food-grade production, ISO-classified cleanrooms, hospital procedure rooms. Visual register: specification-driven, not aesthetic-driven. Performance register: chemical resistance, seamless hygiene, GMP and ISO 14644 compliance. Specification decision point: chemical exposure schedule + regulatory regime determine specific system grade.
System 4 — Engineered Hardwood
Multi-layer engineered hardwood with specification-grade kiln-dried lamella over cross-laminated core. Specified across boardrooms, executive residences, premium hospitality suites, multinational corporate headquarters. Visual register: solid-timber permanence. Performance register: dimensional stability across Ghana’s humidity profile that solid hardwood cannot deliver. Specification decision point: lamella thickness governs sand-and-refinish cycles available across project lifecycle.
System 5 — Anti-Static ESD Flooring
IEC 61340-5-1 compliant conductive or static-dissipative flooring with copper grounding network. Specified across data centres, electronics manufacturing, pharmaceutical manufacturing, surgical suites, diagnostic imaging. Visual register: subordinate to performance. Performance register: documented surface resistance and ground continuity. Specification decision point: required surface resistance class (10⁴ to 10⁹ ohms) determines system selection.
System 6 — Heritage Parquet Restoration
Forensic restoration of colonial-era timber-block flooring — herringbone, Versailles panel, Chantilly pattern — for diplomatic missions, ministry residences, heritage institutional buildings. Visual register: period authenticity. Performance register: contemporary durability paired with original visual integrity. Specification decision point: forensic survey before any specification commitment — replacement-piece feasibility governs project viability.
System 7 — Self-Levelling Compound
Specification-grade pourable compound producing FF35 to FF75 substrate flatness. Specified as the underlay for every premium finish demanding a verified-flat receiving plane — large-format marble, polished concrete to mirror finish, ESD-grade installations. Visual register: not visible (substrate). Performance register: F-number compliance per ASTM E1155. Specification decision point: required FF/FL tolerance against project brief — fitness governs final-finish viability across the entire installation.
System 8 — Decorative Terrazzo
Poured-in-place composite of selected aggregate and cement or epoxy matrix, ground and progressively polished. Specified across hospitality public spaces, cultural institutions, corporate atriums, premier residential entrance volumes. Visual register: monolithic designed surface. Performance register: decade-counted durability across high-occupancy environments. Specification decision point: aggregate density and divider-strip pattern governed by sample sign-off before site procurement.
Cross-System Specification Notes
Premium institutional commissions frequently zone multiple systems across a single building: a marble lobby, polished-concrete corridor, engineered-hardwood boardroom, decorative-terrazzo atrium. Floors GH coordinates multi-system commissions under a single project office — substrate, transition, and warranty are documented as one programme rather than orchestrated across multiple specialist installers. This is the specification advantage of commissioning a project office with depth across all eight systems rather than commissioning per-system specialists separately.
For specification consultation across any of these systems, the Floors GH project office is available. Reach the project office at info@floorsgh.com or +233 270 113 728.
