Pharmaceutical Manufacturing Hall — Spintex Industrial
Pharmaceutical manufacturing hall commission requiring 2400 sqm ISO 14644 Class 8 cleanroom-adjacent epoxy with IEC 61340-5-1 ESD integration. Industrial Floors Ghana coordinated substrate moisture verification, multi-coat application discipline, ESD grounding network installation, and continuity-tested commissioning.
Project Profile

A pharmaceutical manufacturing client operating under international GMP (Good Manufacturing Practice) regulatory requirements commissioned this production hall as the primary solid-dosage manufacturing floor for their Spintex facility. The project demanded floor performance that would satisfy both internal quality audits and third-party regulatory inspection.
Specification Challenge
Pharmaceutical manufacturing floors carry a specification burden that few other sectors match. The client’s regulatory framework required a floor system with zero crevice formation, full chemical resistance to isopropyl alcohol, acetone-based cleaning agents, and concentrated disinfectants, and a surface profile that would permit continuous wet-scrubbing without coating delamination over a projected 20-year service life.
Additionally, the production hall was to house heavy tablet-pressing machinery — imposing point loads demanding a slab with flatness tolerance within DIN 18202 Table 3, Row 4 parameters. Any deviation in flatness would compromise machinery calibration and introduce unacceptable GMP risk. Moisture was a further variable: Spintex’s water table profile elevated slab moisture vapour transmission risk, requiring full ASTM F1869 testing before any coating application could proceed.
Approach
Industrial Floors Ghana deployed its FM2 superflat construction methodology across the 4,200 m² production hall. The slab was poured in laser-guided sections using automated screed rails, achieving flatness readings consistently within the DIN 18202 specification threshold. Each pour section received immediate power-floating and finishing to lock surface tolerance before any thermal movement could occur.
ASTM F1869 calcium chloride moisture tests were conducted at the prescribed intervals across the full slab area. Sections exceeding threshold vapour emission rates received moisture-mitigating primer sealing before the coating system was applied.
The coating specification comprised a two-component polyurethane primer, a 3 mm self-levelling epoxy body coat with anti-static grounding layer, and a pharmaceutical-grade polyurethane topcoat rated for continuous chemical exposure. All floor-to-wall junctions received a 150 mm epoxy cove detail — eliminating the ledge accumulation points that GMP auditors flag in standard skirting installations. The cleanroom annex received a sealed, conductive floor system meeting ESD resistance specifications for the packaging line equipment housed within it.
Laser flatness measurement reports were compiled per pour section and submitted as part of the facility’s GMP documentation package, providing the client’s regulatory affairs team with traceable, signed floor certification.
Outcome
- FM2 flatness certification achieved across 100% of the production hall floor area
- ASTM F1869 moisture verification confirmed prior to coating application, eliminating delamination risk
- DIN 18202 Table 3, Row 4 compliance verified by laser measurement report — full documentation provided
- Cove detailing completed across 1,100 linear metres of floor-to-wall junction
- Project delivered within the 14-week programme, enabling the client’s GMP pre-qualification inspection to proceed on schedule
What This Project Demonstrates
Pharmaceutical manufacturing floors in Ghana’s growing industrial corridor demand a level of specification rigour — moisture testing, flatness documentation, regulatory-traceable certification — that a generalist flooring contractor cannot reliably produce. This project reflects a recurring pattern: pharmaceutical and life-sciences manufacturers arriving at Spintex and Tema Industrial specify floors to international GMP and FM2 standards from the outset, and require a flooring partner whose documentation trail can stand in front of a regulatory auditor. Founded 1975, Industrial Floors Ghana has been that partner for over five decades of Ghana’s industrial build-out.
