Blocked urinals cause disruption, unpleasant odours, and inconvenience for staff, visitors, and customers. Chemassist provides a specialist unblocker, URIC XTREME®, designed to clear hard uric scale and restore urinals to full operation quickly and safely.
With fast UK delivery, facilities managers can act immediately to resolve blockages, keeping washrooms open and operational. URIC XTREME® is trusted across schools, hospitals, offices, pubs, hotels, and public venues to deliver reliable, rapid results without the need for harsh acids or complicated procedures.
Prevention is better than cure. Chemassist’s URIC FREEFLO® provides ongoing urinal maintenance, preventing scale build-up, reducing odours, and keeping pipework flowing freely.
For maximum convenience, our subscription service automatically delivers maintenance chemicals at regular intervals, ensuring your washrooms are consistently protected without manual ordering. Flexible dosing options — manual or automatic — make it easy for facilities managers to maintain hygienic, fully operational urinals with minimal effort and cost.
In commercial drainage systems, blockages and odours often develop gradually due to the build-up of FOG (Fat, Oil, Grease). Enzyme drain maintenance products are designed to address this problem over time, helping keep drains clean, free-flowing and hygienic.

Our specialist enzyme-based products support ongoing drain maintenance, particularly in high-use environments such as commercial kitchens.
We can visit your site to carry out a full inspection, providing tailored recommendations to prevent blockages and drainage issues caused by fat, oil, grease, and other organic waste.
Chemassist® researches, develops, and supplies specialist drainage chemicals to treat and prevent blockages across the entire drainage system — from urinals and urinal pipework to sinks, basins, showers, toilets, gullies, and drains. We also control fats, oils, and grease, keeping your drainage systems running smoothly.
All our products are designed to deliver exceptional performance while requiring the minimum safety measures. They are safe for use on all common surfaces and pipework, including stainless steel, plastics, and ceramics, making them ideal for busy commercial and industrial environments.
Our reputation for reliable service and top-quality products has earned us a loyal client base across schools, hospitals, offices, hotels, public venues, and other prestigious institutions.
"Used the product for the first time and to be honest was a bit sceptical, however, having a urinal that was completely blocked, it was clear within 1 hour - far better than anything I have ever tried previously. Fantastic service from Chemassist into the bargain!!!"
"Very happy with your prompt and efficient service."
"Orpheus was recommended to us by Chemassist for a trial last year, this proved to be very successful in both public and employee areas. We have introduced its application on a regular basis under a Planned Preventative Maintenance regime. We get food and fat washed from plates, hair, chewing gum and tissue in sink outlets plus a few unmentionables! It has reduced our maintenance time, the cost of which far outweighs the cost of the product. Excellent Product."
