Slate from the Herbeumont Quarries comes in two colours: a seam of brown schist and a seam of blue schist. The quarry seam produces blocks and slabs. Some of the blocks are sold to stone masons, the rest are cut up to produce coping stones and tiles.
The slabs are split for use as Japanese stepping stones, paving slabs, gabions and other garden items.
Alongside these traditional products, the quarry has introduced slate chips and paving for garden paths and flower beds, thus creating three products from one. As slate chips are naturally flat, they do not roll underfoot, are comfortable to walk on and hold their position on a slope. In addition, their neutral pH and the fact that their colour does not fade make them highly suitable for garden use.
