About the stone
Getting to know Moheda Black Diabase
A deep black, fine-grained diabase from Moheda in Småland. Often sold as black granite, diabase is a rock of its own, denser and heavier than granite. With water absorption of 0.01 % it is one of the toughest stones Zurface supplies.
Where to use it
As a hard silicate stone, Moheda Black Diabase 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
Småland is the land of red granites and black diabase, with many quarries working since the early 1900s.
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
