Borghamn-limestone
Borghamn-limestone are of high quality and has been used in many historic buildings in the country. The wear resistance has been put to the test in schools and regiments, while the subtly elegant appearance can be seen in churches and cathedrals. In modern construction, arguments like long life, low maintenance cost and recyclable natural materials weighs heavily. With our modern production facility, we adapt the stone by the architect and the client's wishes.

Borghamn-limestone, light grey
Borghamn-limestone is unique. It is closer to 485 million years old, which is twice as old as any other limestone. This makes it a tighter and harder than stone than both limestone and marble from around the world. Swedish limestone is therefore highly suitable as a building material with high strength requirements, such as staircases and floors. Borghamn-limestone is a natural choice of material for floors, stairs, wall facings, window sills or restoration items.
