Materials of the past are inefficient and wasteful

When it comes to building our future, the properties of many traditional construction materials fall short of what’s required to support the infrastructure of a sustainable Australia. The downsides of sticking with the past can include:

heat emitting from house

Heat Loss

Spaces often cost more to keep warm due to the poor insulative makeup of their walls.

Can be unnecessarily high for products produced in a carbon-intensive manner.

Weight Kilogram


Unnecessary density means increased costs associated with transportation and logistics.

Non Robust

Non Robust

Damage from fire, frost, and chemicals can expose your structure to unnecessary risk.

Clinka solves these problems...naturally

Clinka provides a natural solution to these problems of the past and empowers Architects, Engineers, and Owner Builders with the materials to create a greener, smarter, and more efficient society.

Thermally Efficient

Thermally Efficient

Clinka provides excellent thermal insulation to support stable interior temperatures.



It is 100% natural, contains no harmful substances, and has very low carbon life-cycle emissions.



With only 15% of the density of traditional aggregates, transportation is safer and easier.
