About the stone
Getting to know Bohus Grey Silver
A light, fine-grained Bohus granite from around Rabbalshede in northern Bohuslän. The even grain gives it a restrained, almost graphic look, and it splits cleanly, which allows crisp arrises and fine detailing. In Stockholm it forms a pattern with dark diabase on Soltorget by Sergels torg.
Where to use it
As a hard silicate stone, Bohus Grey Silver is supplied for external paving, paving slabs, setts, 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.
Finishes
- split face: the natural split, for walls, block steps and setts
- bush-hammered: evenly textured, the classic finish for squares and plinths
- flamed: rough and slip resistant, for external paving and steps
- honed: smooth and matt, shows the pattern, for interior floors
- polished: deepens the colour, for interiors and facade details
- brushed: softly textured and pleasant underfoot
- sandblasted: finely roughened and evenly matt
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.
