Bohus Grey Tossene

Bohus granite at its most classic: a calm grey ground with evenly spread grains in black, beige, green and soft pink. It is the stone of Swedish churches, harbour quays and town squares, and one of the granites Zurface ships most often. An EPD is available.

Where to use it

As a hard silicate stone, Bohus Grey Tossene is supplied for external paving, paving slabs, kerbs, block steps, facades, interior flooring and interiors. For external surfaces we recommend a flamed, bush-hammered or blasted finish, which keeps its grip when wet. Thickness and format for paving depend on traffic load and bedding; we size them with your engineer against EN 1341 to EN 1343.

Origin and geology

Bohuslän on the west coast is Sweden's best-known granite country. Quarrying here has run at industrial scale for close to two centuries, and Bohus granite was shipped to harbours and cities across Europe.

Granite, quartzite, gneiss and diabase are silicate rocks: hard, dense and unaffected by acids. They are the stones for facades, squares, setts and steps, wherever stone has to take frost, de-icing salt and traffic.

Supply and documentation

Zurface supplies Bohus Grey Tossene as slabs, treads, setts, cladding and cut-to-size pieces, delivered to site. Every quote comes with the declaration of performance (DoP) and CE marking. See Specifying Swedish stone for standards and tender wording.
