Waterproof Concrete Down Under

In 1962, field trials were conducted by the Engineering and Water Supply Department in tidal salt pans in the desert regions of Southern Australia. Soil analysis showed very high levels of chloride and sulfate salts. These caused rapid deterioration.

After 30 years of exposure in the Sabkha salt pan, the waterproof concrete has remained virtually unaffected. Otherwise-similar ordinary Portland and sulfate-resistant cement concretes have all but disintegrated.

Completed in 1963, the roof of the original Cadbury Fry Pascal Factory in Collingwood, Australia is still being effectively waterproofed and protected with waterproof concrete. Ponded water on top of the building serves as thermal mass for cooling.

At the Cairns "Reef Casino" in Queensland, Australia, there is a suspended, landscaped rooftop atrium deck. This post-tensioned waterproof concrete deck supports the rooftop glass-pyramid atrium and is covered with soil, plants, and water features.

At the Coolangatta "Showcase on the Beach" in Queensland, Australia, the waterproof concrete podium deck and suspended swimming pool deck incorporate tennis courts, a landscaped roof garden, and recreational areas. This concrete is also protected against airborne chlorides for maintenance-free, design-life durability.
