Dromana topping is also known as Decomposed Granite. It is a decorative, light brown coloured topping that compacts well, reducing drainage properties.

Best Suited For:

Driveways and paths, an alternative to concrete or paving, can be used anywhere a compacting material is required and drainage is not an issue.
