A BlueRinse Concrete Washout unit was used in order to safely manage deliveries of concrete, notably achieving 70 chute washes in one day using just one Nappy Sack. Washwater was recycled for the whole project with no need to discharge.

Mudtech also assisted with treatment of high pH water arising from the tunnelling operations using pH Blue. We provided lubricants, flocculants and DryAdd in order to support safe production with low negative environmental impact.
