Hillview 5mm grey crushed topping is a decorative 5mm minus grey granite. The compactible product, also known as Dromana topping or granitic sand, looks great on driveways and paths and is also widely used by plumbers as a pipe bedding material.
Apply at a depth of 25-40mm. Use a vibrating plate for best results or simply rake out and tread down to pack for firm finish. After compacting lightly, spray water to settle all the fine particles.
