Our Building Material Solutions

Cleancrete

Cleancrete is the building material containing our Oxacrete admixure. It is based on earthen excavation material and can include construction waste. Cleancrete can be applied to build floors, screed, non-load bearing walls and interior and exterior elements.

Impact

  • CEMENT cement-free
  • high circularity
  • earth-based
  • up to 90% CO2 reduction compared to conventional cement based concrete
  • low energy intensity

Cleanbrick

Oxabrick admixture is used to produce Cleanbricks with extrusion or compression processes. Cleanbricks are cement-free and non-fired, which reduces the environmental impacts of the material. Cleanbrick can be used to construct masonry walls.

Impact

  • non-fired
  • CEMENT cement-free
  • high circularity
  • earth-based
  • up to 85% CO2 reduction compared to conventional fired bricks
  • low energy intensity
