Bio Blocks

Bio Blocks rapidly digest urine crystals, keeping toilet channels and drain lines running freely.

Perfumed to provide a pleasant, long lasting fragrance in the washroom.

Unlike traditional channel blocks, they are pDCB free (pDCB is recognised as being a carcinogenic material and a water polluter).
Note - when using Bio Blocks, avoid the use of bleach or caustic/acid cleaners as these will affect the biological performance of the Bio Block. We recommend the use of Bio Clean as a washroom cleaning chemical).

Application: place in urinal troughs approximately 40cm apart.
