Lammin Betoni Ltd is a family-run business founded in 1956 and a pioneer in stone construction. Product innovations that have shaped the industry over the decades – such as the first insulated concrete blocks on the market – established Lammi as a pioneer in its field many years ago. That is why the products and methods used today can almost always be traced back to Lammi.
