Launched in November 2020, just in time for summer in South Africa, the Postmasburg municipal water storage reservoir now provides the growing community a secure and constant supply of drinking water. PENETRON ADMIX was used to ensure a waterproof – and non-toxic (NSF-61-certified) – solution for the enormous concrete structure.
Located in a well-known agricultural and mining district in the Northern Cape province of South Africa, Postmasburg has approximately 30,000 inhabitants, at the moment. “Postmasburg is a growing community and the local infrastructure is being expanded to accommodate the population growth,” explains Adriaan Erasmus, Penetron South Africa Project Engineer. “The newly-completed water reservoir is part of a new housing development.”
Bigen Africa, the project’s consulting and structural engineers, approached Penetron South Africa about a waterproofing solution for the massive, 12 million-liter water storage structure. The Penetron technical support team specified a durable waterproofing solution. A Penetron-certified contractor, Razzmatazz Construction, ensured the successful implementation of the Penetron System.
Permanent Environmentally Friendly Protection
“The primary objective for the Postmasburg project engineer was to have a durable and waterproof concrete structure with minimal future maintenance,” adds Adriaan Erasmus. “The continuous crack self-healing capabilities provided by PENETRON ADMIX gave the engineers the peace of mind that sealed the deal for Penetron.”
The ready-mix concrete supplier, Poort Beton, added PENETRON ADMIX to 3,000 m3 of concrete during the batching phase. Once added to the mix, PENETRON ADMIX becomes an integral part of the concrete matrix and performs consistently during the service life of the concrete.
“PENETRON ADMIX is also NSF-61 certified. That means the admixture is completely non-toxic and contains no VOCs – ideal for potable water applications like the Postmasburg water reservoir,” concludes Adriaan Erasmus.
Waterproofed concrete: PENETRON ADMIX, an NSF-61 certified admixture (non-toxic/no VOCs), was added to 3,000 m3 of concrete for construction of the Postmasburg water reservoir in South Africa.
