Basalt Natural Stone Flagging is available in a C Grade which is a thin basalt perfect for doing walkway / footpath or as a feature in your garden.
D Grade Basalt can be used the same as C Grade. It will vary in size but will also be thicker than the C Grade, so it’s more durable for areas that require thicker flagging.
G Grade Basalt are used as steps. Perfect for gardens and entrances to the perfect spot in your garden or yard
