ClinkaCRETE is a low density concrete material made with expanded Clinka clay and recycled crushed concrete. Clinka is a 100 per cent natural material, and its breathable qualities contribute to a healthier, chemical and mould-free indoor environment. It is non-biodegradable, non-combustible, and resistant to attacks from moisture, frost, and chemicals.

Clinka can also be used in standard concrete blends as lightweight aggregate to reduce weight and improve thermal performance.
