Raising the Standards in Biotech Flooring
Application Area: Clean Rooms, Technical Areas, Warehouse
A global leader in flexible hose solutions for the pharmaceutical and chemical industries has constructed a 1,800 m² clean room facility in Barcelona, Spain. As the company continues to expand its biotech operations, this new build construction required more than just functionality for its flooring; it demanded flawless performance, industry-grade hygiene and a future-proofed finish.
Challenges & Customer Requirements
As part of its growth strategy, the client needed to install ISO 7-classified clean rooms to produce high-purity hoses. The stakes were high: previous trials with other flooring companies had failed to meet the client's quality expectations, resulting in poor finishes and underwhelming durability.
This facility had to set the gold standard for day-to-day operations and serve as a showcase model for future projects. The flooring system had to:
- Meet ISO 7 clean room classification requirements
- Withstand significant chemical exposure and mechanical wear
- Provide a seamless, hygienic, easy-to-clean surface
- Reflect a premium, professional appearance

Solution
To validate performance before committing, the client's representatives visited one of Stonhard Spain's major installations in Barcelona. Seeing Stonhard's systems in action and speaking with satisfied end-users gave them the confidence to move forward.
Stonhard proposed Stonclad GS/HT4, a high-strenght epoxy mortar system tailored for demanding environments. Three distinct finishes were chosen for optimal functionality and design cohesion:
- Clean Rooms (ISO 7) - Slate: Offers a seamless, anti-microbial surface ideal for sterile operations.
- Technical Areas - Silver Gray: Provides a clean, industrial look with enhanced wear resistance.
- Warehouse - Pewter: Delivers toughness and longevity in high-traffic zones.
Because this was a new construction, there was no need for substrate removal, allowing for full control over the preparation and installation process. With no margin for error in clean room applications, Stonhard Spain's experienced team ensured flawless execution from start to finish.
What made the difference? Stonhard's track record in biotech and pharmaceutical environments meant we understood the critical tolerances involved. Every specification, from chemical resistance to slip ratings and finish uniformity, was met without compromise.

The organisation now operates a clean room facility that meets and exemplifies ISO 7 requirements. The robust, hygienic, and visually cohesive environment supports the company's advanced manufacturing processes and sets the stage for global replication.
This project is more than a flooring success story; it's a statement of trust, technical excellence, and strategic partnership for Stonhard Spain.
