Floor drains in hospitals are not just a sanitary issue — the biofilm in the P-trap has been documented as a reservoir of resistant strains such as Pseudomonas aeruginosa, CRE, and Klebsiella pneumoniae. Studies published in the Journal of Hospital Infection show aerosolisation of pathogens when water is flushed. Green Drain™ is a physical one-way seal with SGS-proven blocking of >99.9 % of viral aerosols.
Hospital rooms, bathrooms, ICUs — every floor drain after patient discharge or extended room vacancy exposes the space to pathogen aerosolisation. Literature published in the Journal of Hospital Infection and the American Journal of Infection Control has documented drain-associated outbreaks across acute settings.
The HSE-funded network includes HSE-run acute hospitals and Section 38 voluntary hospitals (the Mater, St James's, Beaumont, Tallaght, the UHL Group and others), serving thousands of inpatient beds nationwide. Every ward, every ICU, every isolation room and every staff washroom has floor drains that represent a potential vector for HCAI under HSE SARI guidelines.

Our technical team works with the epidemiologist, the chief nurse, and the technical service — from mapping to delivery.
The technician maps all drains (rooms, bathrooms, washroom blocks, kitchen blocks). We measure the internal diameter and the type of grate.
Written recommendation with sizes (GD 1.25 to GD 6), total number of pieces, and specification according to EN 1253-1.
We place samples in five representative rooms for seven days. Your infection control lead assesses the effect on swab results.
Your maintenance team can do a whole department in a day. No downtime, no plumber, and nothing to come back for.
Irish HSE hospitals are typically built to EN 1253 standard. P-traps in patient rooms and sanitary units are predominantly 1.5″ (38 mm) — the most common size. Operating theatres, sterilisation areas, and central kitchen drains use larger diameters. A typical acute hospital requires four to five different sizes throughout the building.
Yes. The silicone material is resistant to sodium hypochlorite up to 5 %, quaternary ammonium compounds, isopropanol, and ethanol at standard hospital concentrations. A detailed chemical compatibility list is provided upon request.
Use a standard drain disinfectant. The seal is not taken apart or removed for cleaning — treat it exactly as you would a standard U-bend, with a visual check once a month.
The expected service life is about five years in normal use. Tested to ASSE 1072-2020 for over 2,500 opening and closing cycles.
Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (drain unblocking).
Patented silicone seal for floor drains in washrooms, wards, operating theatres and ICUs. Documented barrier for IPC programmes.
Bio-enzymatic urinal tablets for public washrooms and clinics. They cut staff and patient exposure to the odour and bacteria that come with urinal scale.
Biological cleaning of biofilm in the drainage runs from hospital washrooms. Reduces the microbiome reservoir in P-traps and sewer pipes.
We come to the site, map the drains, and provide a written recommendation — no cost, no obligation.
