Having our own quarries, the majority of which are in Southeast Finland, guarantees reliable supplies.

Baltic Brown V

Baltic Brown V

In response to the needs of our customers, we expanded our range with Baltic Brown V granite, which we extract from the quarry we opened in 2007. The new grade is dark brown.
