Operating theatre and cleanroom flooring: hygiene, static electricity control and heavy loads

Last updated: 3 November 2026

Why ‘antistatic ≤ 2 kV’ does not constitute an ESD floor, how to select SD or SC, which homogeneous flooring is suitable for heavy machinery, and how to seal th

In an operating theatre or cleanroom, the floor is not merely a surface — it is a safety feature. It must simultaneously prevent the accumulation of microbes, dissipate static loads that endanger equipment, and withstand heavy loads and aggressive disinfection for decades. None of these requirements are met by ‘a good tile’. They are met by a seamless, thermally bonded floor, together with a ceiling that keeps the space airtight.

The five non-negotiable requirements

Requirement	What this means in practice	How it is documented
Infection control & hygiene	A continuous surface with heat-sealed joints — with no areas where microbes can accumulate	ISO 846 — does not promote bacterial growth; EN 13553 — watertightness
Resistance to disinfectants	Daily aggressive disinfection without causing wear or discolouration	ISO 8690 — excellent disinfection
Low particle emissions	The flooring does not contribute airborne particles to the ambient air	ISO Class 3 cleanroom
Control of static electricity	Load relief to prevent equipment malfunction	EN 1081 · EN/IEC 61340-4-1
Resistance to heavy loads	Operating tables, radiology equipment, wheeled units leaving no permanent marks	Remaining entries · category 34 / 43

Antistatic, dissipative, conductive: three different things

The most misunderstood requirement is the control of static electricity. Almost every modern vinyl product states ‘antistatic ≤ 2 kV’ — and this not This is flooring for ESD areas:

Category	What matters	Price	Where required
Antistatic	The force exerted on the body whilst walking	≤ 2 kV	Offices, corridors — comfort, with no ‘wobble’ in the handles
Static Dissipative (SD)	Electrical resistance to earth	10⁶ – 10⁸ Ω	Laboratories, cleanrooms, server rooms — controlled, gentle pressure relief
Static Conductive (SC)	Electrical resistance to earth	5×10⁴ – 10⁶ Ω	Operating theatres, radiology departments, intensive care units — rapid load relief

Anti-static flooring simply does not build up a static charge in the body. SD and SC flooring are connected to the building’s earthing system and actively dissipate loads — which is why it is a system rather than a property of the roller shutter.

Why don’t we choose ‘the most conductive option to be on the safe side’?

The correct category is determined by the site survey. An operating theatre requires static conductive for rapid venting; an electronics workshop often requires static dissipative, because excessively rapid discharge can damage sensitive microcircuits. Conductivity is specified — it is not maximised.

On the website, we provide the LINOLEUM CONDUCTIVE xf² — conductive linoleum with R ≤ 10⁶ Ω in accordance with EN 1081 and EN/IEC 61340-4-1, Bfl-s1, naturally antibacterial. The Tarkett conductive vinyl ranges iQ Toro SC and iQ Granit SD Specifications are provided on request — please contact us for the appropriate class for each area.

Homogeneous vinyl flooring for healthcare facilities

Homogeneous vinyl flooring features colour and pattern throughout its entire 2 mm thickness, a wax-free iQ PUR surface and can be restored by dry polishing. All of the following apply ISO Class 3 cleanroom, Bfl-s1 and category 34 / 43 — the selection is made from the remaining options:

Collection	Distinguishing feature	Where it fits
iQ GRANIT	Classic granular finish; grain size ≤ 0.10 mm; also approved for use on ships	The ‘foundation’ of every hospital specification
iQ MOTION	Terrazzo finish · surface tolerance ≤ 0.02 mm, the best in the iQ range	Surgery and imaging using heavy, stationary machinery
PRIMO PREMIUM	Smooth, granular finish; 0.03 mm texture; 30 colours	Spaces with trolleys and shelving
iQ OPTIMA	55 colours · roll or 61 × 61 tiles · acoustic version 16 dB	Colour-coded zoning, hospital wards
iQ NATURAL	Plasticiser made from renewable raw materials; 2.24 kg CO₂eq/m²	Projects with environmental criteria
iQ EMINENT	Three-dimensional depth effect · 26 colours	Areas where appearance matters — reception areas, corridors
iQ MEGALIT	Coarse-grained with a pearlescent sheen; seam strength ≥ 400 N/50 mm	High-traffic communal areas

Wet rooms: preparation, sanitisation, showers

In hand-washing, sterilisation and staff shower areas, the uniform surface must be non-slip. The GRANIT SAFE.T contains integrated aggregates throughout its thickness (EN 13845), Class C for barefoot use in accordance with EN 16165, R10/R11 on request, 0.02 mm indentation and watertightness in accordance with EN 13553 — and is colour-coordinated with iQ Granit, so that the transition from the dry to the wet area is imperceptible.

Flooring as a system, not as a roll

Substrate: Completely smooth and level, using high-strength self-levelling compound. Any unevenness is transferred to the sheet and creates a point of wear.
Conductive copper tape: an earthing mesh beneath the conductive floor, connecting it to the building’s earth system.
Conductive adhesive: ensures electrical continuity between the floor and the tape — standard adhesive negates conductivity.
Thermal welding of joints: 4 mm cord in the colour of the flooring, which joins the sheets together to form an impermeable surface.
Wall mounting: The floor rises up the wall to form a recessed channel, and is finished with a skirting cap — CAP 3 with a base and cover for maximum hygiene.

ARGYNET Note

The success of a healthcare flooring installation depends on the details of the earthing and bonding, not just on the choice of roll. An excellent conductive floor laid with the wrong adhesive or without a proper copper mesh ceases to be conductive. Resistance is measured after installation, prior to handover.

At ARGYNET, we specify the entire system — flooring, membrane, adhesive, cord, levelling — and calculate materials per m².

The roof: the second control surface

In operating theatres and intensive care units, the suspended ceiling ceases to be merely a finish and becomes part of the sanitary envelope: it must remain airtight so that the space maintains its differential pressures, accommodates lighting fittings, air inlets, HEPA filters and medical gases without leaks, and is cleaned using the same protocols as the floor.

24 SYNCRO EVO · Atena H+: A suspended ceiling system for clean rooms, with 600 × 600 and 600 × 1200 mm panels, in pre-painted aluminium or steel and with an antibacterial finish.
TAURUS EVO · Atenalux: Lighting fixtures for clean rooms with IP65 protection, antimicrobial white paint, CRI > 90 and DALI or tunable white control.
METAL BOARD Rg2516: accessible metal suspended ceiling with sound absorption a_w 0.70 and A2-s2,d0, for corridors and ancillary areas.

In Onassis National Transplant Centre, ARGYNET supplied 630 m² of clean-room suspended ceilings and 180 LED light fittings for the Intensive Care Unit and the High-Dependency Unit.
