NB 1 Grey

We are delighted to announce the achievement of the British Board of Agrément (BBA) certification for NB 1 (19/5619i1).  Koster NB 1 is a mineral coated waterproofing slurry containing crystallising and capillary-plugging agents. It can be used for waterproofing against ground moisture and for non-pressurized and pressurized water.   NB 1 Grey is characterized by its excellent resistance to pressure and abrasion as well as chemical and sulphate resistance.

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 into their structural waterproofing projects.

Who is the BBA and what is BBA Approval?

Soffit Application of NB1 and SB Bonding emulsion with Repairmortar filletsThe British Board of Agrément (BBA), is the UK’s major authority for the evaluation and certification of construction products.  For manufacturers (such as Delta) to achieve BBA Approval for a product, the product must go through rigorous laboratory tests, on-site evaluations and thorough manufacturing assessments.  If the product successfully meets all the criteria it is awarded BBA Approval and Agrément Certificate.

Why is BBA product Approval so important?

Koster_NB_1_BBA_QR_Code copyBBA Approval is an independent assurance that a product will perform as the manufacturer claims it will.  The BBA’s reputation for robust testing gives the NHBC, builders, specifiers, local authorities, and others within the industry reassurance that a product is of a consistent quality, will perform and will last.  As the British Board of Agrément say “BBA products won’t let you down!”

Our current BBA Certificates (00-3742 and 18/5509) covers Approvals for Delta MS 20, MS 500, FM, PT and Koster Deuxan 2C. Also Delta’s Memtech M1 Gas Barrier and Memtech R1 Gas Barrier Certificate number 16/5367.
