Blue Crusher Dust is crushed hard rock down to 5mm. Compacting qualities are highly regarded in the local area. This mix of small rock and fines means that when compacted, it binds together well and creates a strong, stable surface to work on. Most commonly used as the base for artificial/synthetic lawns or paving, providing a much firmer base than sand. Also used as a trench base for drainage pipes.

This product can be mixed with cement at 1-8% to create a firmer material if desired. It is much less expensive than other rock based mineral supplements on the market.
