Industrial plants and warehouses have large floor drains and central trenches. Hydrogen sulphide from the biofilm corrodes reinforcement bars, services and electronics. Methane and other gases accumulate in poorly ventilated spaces — an explosive hazard. Green Drain™ is a safety measure, not a luxury.
In a big plant everyone minds their own patch — nobody looks at the floor drains. Biofilm grows, H₂S corrodes metal, and gases accumulate.
EU Directive 2014/34 (ATEX) regulates the protection of equipment for explosive atmospheres. Workplace hazard controls in industry are subject to statutory inspection. For food logistics, BRC and IFS audits require environmental monitoring as standard.

Industrial sites have scheduled shutdowns. Our technicians go in during that window, fit the seals and are out again.
Plant mapping — process, cold storage, shipping, sanitation.
The QHSE department takes the documentation for environmental compliance.
One line or chamber — 30 days, H₂S measurement at strategic points.
During the planned shutdown — the entire plant in 1–3 days.
Irish industrial sites range from pharma manufacturing in Cork and Limerick, FMCG and food-logistics distribution centres around Dublin / Naas / Ballymun, cold-storage and 3PL hubs along the M50 corridor, to data centre support facilities and chemical warehousing under IDA Ireland and HSA oversight. A typical Irish site runs 4–6 different drain sizes across production, sanitary and utility zones.
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 manufacturing and warehouses. H₂S and methane barrier. ATEX-compliant design.
Bio-enzymatic urinal tablets for staff washrooms. EU 528/2012 BPR, documentation for EHS systems.
Biofilm bio-cleaning in production floor drains. CIP/SIP-compatible, and it does not interfere with the plant's cleaning chemistry.
We come to the site, map the drains, and provide a written recommendation — no cost, no obligation.
