Our revolutionary NappySacks, self dosing bags which separate the solids, whilst automatically reducing the pH of the water, have been used on section 2C of Phase 2 of the project, near Bletchley.

The NappySacks have had a noticeable impact in helping in the dewatering set up and Jose Chicharro, Environmental Advisor at Volker Rail, was full of praise for them; "I'm happy to report that your NappySack concrete washout bags are performing really well in my dewatering set up, and are removing 99% of the silt. I will definitely consider using more of your bags in the future".
