uridan uriLOCK® – 5.0 L Blocking Fluid for Waterless Urinals

uridan uriLOCK® is the dedicated blocking fluid that makes uridan waterless urinals work. Because it is lighter than urine, it floats on top of the liquid in the trap and forms a liquid barrier, preventing sewer gases from escaping into the room while still allowing normal use to drain away.

The 5.0 L canister is the bulk option for larger sites and service contractors looking after multiple urinals. It’s the economical choice for stadiums, shopping centres, office towers, schools and councils where regular top-ups are part of a planned maintenance routine.

Decant from the 5.0 L canister into smaller service bottles or dose directly on site according to uridan’s instructions. When used alongside the recommended cleaners, uriLOCK® maintains an effective odour seal without the need for any flush water, delivering reliable performance and significant water savings across the life of the installation.
