We operate from our company owned premises based in Maitland, Cape Town and Stormill, Johannesburg. From these locations we serve the entire South African and Southern African region. In addition, we export to distant countries as necessary.
For more than a decade we have been the exclusive supplier in South Africa of the Italian Casali torch-on waterproofing membrane.
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.
