The problem
Diamond-polished concrete with mirror finish for premium retail and corporate.
Our approach
Polished Concrete Floor Systems
Multi-pass diamond polishing achieves a mirror finish that meets institutional traffic specifications without sacrificing visual ambition.
The Challenge
In high-traffic institutional environments — banking halls, diplomatic reception areas, corporate atria — the floor is not incidental. It is the first surface every visitor reads, and the one that absorbs the cumulative punishment of thousands of footfalls each week. Concrete, left unsealed or finished to a low standard, degrades visibly within months: surface dusting, micro-crack propagation, and a progressive loss of the reflective quality that signals specification-grade commitment. For the facilities manager of a Tier-1 institution, that degradation is a reputational problem as much as a maintenance one.
The technical difficulty is compounded by Ghana’s sub-slab moisture environment. Without rigorous pre-installation testing, moisture migration from the substrate compromises coating adhesion, produces delamination, and ultimately shortens the usable life of even a premium finish. Many flooring contractors in the market offer a single-pass grind-and-seal approach — a method that addresses appearance in the short term while leaving the structural and moisture problems unresolved beneath the surface.
Institutional clients require a methodology built around longevity, traffic tolerance, and verifiable quality at every stage — not a surface treatment applied over an unprepared substrate.
The Floors GH Solution
Since 1972, Floors GH has refined a multi-pass diamond polishing methodology specifically calibrated for Ghana’s institutional sector. The process begins with sub-floor moisture testing to ASTM F2170 standard and ICRI Concrete Surface Profile verification before a single pass of any diamond tooling is made. This pre-work phase is non-negotiable: it determines the correct grit sequence, primer selection, and densifier chemistry for the specific substrate presented on that site.
Diamond tooling progresses through a controlled sequence — coarse-cut passes for surface levelling, mid-range passes for scratch removal, and fine-grit polishing stages that build toward the mirror finish institutional specifications demand. A penetrating lithium silicate densifier is introduced at the appropriate intermediate stage to harden the surface from within, increasing abrasion resistance and reducing long-term maintenance requirements. The process closes with a multi-stage quality control sign-off: substrate condition, primer adhesion, mid-coat uniformity, and final-finish reflectivity are each recorded and signed against the project specification before handover.
The result is a polished concrete floor that meets the visual ambition of premier institutional interiors while carrying a written guarantee appropriate to the investment made.
Material + System Specification
- Sub-floor assessment: ASTM F2170 in-situ relative humidity probe testing; ICRI CSP verification to confirm coating adhesion tolerance
- Diamond tooling sequence: Metal-bond coarse cut through to resin-bond fine-grit polish; grit progression calibrated per substrate hardness and finish specification
- Densifier chemistry: Penetrating lithium silicate densifier applied at mid-sequence to harden and dust-proof the concrete matrix
- Self-levelling underlayment (where required): Bubble-eliminating roller technique eliminates entrapped-air defects in finish-coat applications
- Quality checkpoints: Four-stage QC sign-off — substrate, primer, mid-coat, finish — each recorded against project specification
- Anti-static compliance (data centre and electronics adjacencies): ESD grounding-strap continuity testing post-installation where the brief requires it
Typical Project Profile
A standard polished concrete engagement for Floors GH spans 400–2,500 square metres across banking halls, corporate headquarters atria, premium hospitality back-of-house and public areas, pharmaceutical manufacturing facilities, and diplomatic compound reception floors. Project timelines run from twelve to thirty working days depending on substrate condition, required finish grade, and phased-access requirements. Site mobilisation is coordinated through the Floors GH project office to minimise operational disruption to the client’s ongoing activities.
Outcomes
- A mirror-grade reflective finish that meets institutional specification without surface sealer dependency
- Measurably increased surface hardness and abrasion resistance through densifier penetration, reducing long-term maintenance cost
- Verifiable sub-slab moisture compliance, eliminating the most common cause of post-handover delamination failure
- A written project guarantee backed by 54 years of institutional flooring practice and a Tier-1 client roster across Ghana’s banking, diplomatic, and hospitality sectors
- Full QC documentation package delivered at handover — substrate records, material data sheets, and sign-off logs available for facilities management reference
