About us

From a peripheral venture to a pioneering partner – read our story and meet the Betolar team.

Our story

Betolar is a Finnish pioneer company in materials technology. Our story began with a bold experiment to replace cement used as a raw material for concrete with a side stream-based material. From the beginning, it was clear that something great could be achieved with these geopolymers – something – that would change the way we make products and use raw materials.

At the heart of Betolar are visionary thinking, a high level of expertise in construction, and a deep understanding of the opportunities offered by technology and digitalization.

Today we have grown to be a pioneering partner, helping the construction industry to build a new, more sustainable future. We help reduce CO2 emissions and the usage of fossil resources in order to achieve climate goals in practice.


With us, you will build a continuous competitive edge.
