In a facility from the 1960s/70s, the client was looking for a solution to contain contamination in various transitions between offices, production areas, and common areas without creating obstacles and delays for the operators’ transit. The washable antibacterial decontaminating mat CZ, used as an invisible barrier, offered the most effective and operational solution without slowing down the normal passage of many operators, even with doors operated by personal badges. Given the tiled flooring, which was not suitable for proper installation in one of the affected areas, the client realised a smooth, compact, and non-porous resin coating of approximately 2×4m installed, on which the mat was then placed. The photos show the before (dark brown tiles), the during (grey resin coating), and the final installation (blue mat).
