Australian Bush Rocks

Did you know?

A little bit of history on the humble Bush Rock.

You may well have come to our website knowing you want some Australian bush rocks for your retaining wall, stone wall, rockery or landscaping project, which is great and we’re ready to help, but have you ever wondered why we use bush rocks for these purposes or how they came about, or even what other people have used them for over the centuries?

Ancient Structures

Bush rock has always had a place on history. Egyptians were one of the first civilisations to quarry bush rock for use in their structures, in fact, many of their structures consisted of bush rock. Their skill with cutting the rocks to size resulted in them fitting together so well that not even a sheet of paper could be slid between them.

Global Phenomenon

Various other civilisations integrated bush rock into their building and structure creations over the centuries simply because its availability in most parts of the world was abundant. The proof of its longevity and structural ability are still seen around the globe in ancient buildings still standing as testament to its durability.

Endless Uses

Bush Rock was not only used for building dwellings and statues, it became popular in pillars, posts, fencing, fireplaces and mantle tops. These days, a very common use for it is retaining walls; simply because it fits naturally into the landscape while at the same time lasting almost indefinitely; unlike timber or other lesser solutions.

Natural Beauty

Bush rocks themselves are very versatile due to their nature and when used for purposes other than walls and landscaping can be cut and polished to a smooth glassy texture. Their natural beauty has also lead to them being used for decorative purposes such as tiling, bridges and monuments.

Igneous Rock

Bush rock is an igneous rock (meaning it was created from solidified volcanic lava or magma) and it consists of large individual grains visible to the naked eye. The most common components that make up bush rock are quartz, feldspar and small amounts of mica, amphiboles and other minerals. This combination tends to give bush rock a gray, red, or pink color, with dark grains speckled throughout the rock.

Earth's Crust

Did you know Earth’s continental crust consists mainly of bush rock? Bush rock is found in the landscapes of most mountain ranges which were created millions of years ago. These large mountain granite fields are called Batholiths.

Bush To Sandstone

Bush rock is also found in the core areas of continents which are known as shields, formed by molten rock material that cooled slowly beneath the Earth’s surface over long periods of time. The rocks found lying on the ground have been pushed up from beneath the surface by years of natural errosion. Aged and severally weathered, bush rock eventually becomes sandstone, though this takes a very long time. Wherever sandstone is abundant in the landscape, you are likely to find bush rock also.
