Sea World in Australia’s Penguin Encounter exhibit is home to a large waddle of King Penguins, the world’s second largest penguin species. The designers wanted to create an environment that looked as natural as possible, while retaining the required engineering attributes.

The ambient summer temperature in sub-tropical Queensland is close to 40 degrees Celsius, but the penguins’ water is chilled to two degrees Celsius. The constant movement at the waterline creates both significant physical wear on the concrete structure as well as temperature variation.

Kryton’s Krystol Internal Membrane (KIM) was chosen as a solution for waterproofing the artificial rock in the exhibit. KIM’s self-sealing ability means that despite temperate changes, the wearing effects of the waterline and penguins clawing at the rock, the waterproofing will remain durable and reliable for the lifetime of the structure.
