Blue Slate 20mm is one of our most popular decorative aggregates. It has a blue/grey/plum colour that darkens when wet, it is suitable for garden borders, landscaping projects, and perfect for pathways where a flatter finish is required. It can also be used in water features and ponds as it is fish friendly. We also have this available in 40mm.
