Products listed below have been assessed and pre-qualified as meeting the required Transport for NSW Specifications and are suitable for consideration on the classified road network. The assessment process includes verification of quality systems, product materials and manufacturing to relevant TfNSW Specification clauses and Australian Standards. Installation design and construction must still be undertaken in accordance with relevant specifications and standards, and separately assessed to determine project specific suitability.

Products not listed below may still be acceptable to TfNSW, but should be assessed by the individual TfNSW project team for suitability. It is not the intention of the list to imply that other products are not acceptable.

The drainage product list should be read in conjunction with relevant TfNSW Specifications, Australian Standards, and Austroads Guides to Road Design.
