.Four Mile Sandstone is the leading supplier of raw sandstone products to South-East Queensland.  Operating out of Gunalda (north of Gympie) Four Mile Quarry can cater to all your needs from crushed decorative gravel to pitching rock, road base and rock wall boulders.

Also known as Gympie granite, due to the strength of the rock, has tested as metamorphosed quartz sandstone making our rock ideal for strength and stability when building rock walls but retaining the appearance of Sandstone. Having been tested as metamorphic conformation allows us to make a quality road base with good compaction and high CBR, which is tested regularly.
