VRJ GROUP

Environmentally friendly concrete building

Helsinki City sport halls (Helsingin Liikuntahallit Oy) and the construction company VRJ worked together with Carbonaide and Rakennusbetoni ja Elementti Oy to use carbonated wall elements in a new ice sports hall.

The challenge

Helsinki City sport halls (Helsingin Liikuntahallit Oy) wanted to explore new building materials and build a new low-carbon ice training center in Kivikko in Helsinki, Finland.

The solution

VRJ Group decided to use insulated wall blocks, which have been manufactured with the Carbonaide CO₂ curing technology. The construction was started in the summer of 2024 and was completed in 2025. A total of 10 tons of CO₂ was mineralised in the walls.
