Our Koster Deuxan 2C, (a two component polystyrene-free, fibrated, polymer modified bitumen thick film sealant) for the safe waterproofing of building structures has also achieved British Board of Agrément (BBA) certification (18/5509).

“The BBA’s certification of Koster NB 1 and Deuxan 2C is a significant milestone for these excellent products, the symbol of quality and reassurances in our structural waterproofing solutions. We believe that this will provide Specifiers, Architects, Engineers and Contractors alike with even greater confidence when specifying Koster NB 1 and Deuxan 2C into their structural waterproofing projects.

We shall continue to lead the field in structural waterproofing and hope to continue our progress by having more products certified by the British Board of Agrément”.
