Verdalskalk produces Tromsdal limestone, which is renowned for its unique purity.

The company was established in 1991 through a merger of the Hylla division of Franzefoss Bruk A/S and Faxe Kalk Norge AS (formerly Reidar Svendsen & Co) in Tromsdalen and Port of Verdal.

The story dates back to 1897 when the first limestone business started with the Hylla Kalkverk lime works.Today, the company is a medium-sized enterprise in the Trondheim region with around 60 employees distributed between four sites: Tromsdalen, Verdal Havn, Hylla and a transportation department.

The particularly clean Tromsdal limestone and thorough quality control during the production processes produce high-quality products.

The owners of the Verdalskalk production company are:

• Franzefoss Bruk AS (55%) – owned by Franzefoss Minerals AS
• Faxe Kalk AS, Denmark (35%) – Faxe Kalk is owned by the Belgian company Lhoist
• Nordkalk OY AB, Finland (10%)
