Our liquid products, produced in our own factories, have been in the market since the late 1970’s and are well established in terms of quality and performance. These products were initially branded under the VIASEAL name when the business operated as a division of VIALIT (PTY) Ltd a subsidiary of Mobil South Africa, later to become ENGEN PETROLEUM. Rebranding to the WATERBLOK name was undertaken subsequent to the sale of VIALIT and the formation of DALVEN PRODUCTS during 1997.
