White Rock Quarry

Heidelberg Materials acknowledges the importance of working with and supporting local communities through the operation of White Rock Quarry. In South Australia, Heidelberg Materials directly employs approximately 150 people and indirectly supports many hundreds of additional jobs through haulage contractors, suppliers, trades and professional services, helping to build the infrastructure for communities by working with and being part of them. Many South Australian businesses — from landscapers and suppliers through to building and road construction companies — utilise material supplied by Heidelberg Materials.
​
The White Rock Quarry site has been highlighted by the State Government as a Strategic Resource Area (SRA). An SRA is an area within the greater Adelaide region or near a regional centre that is of key economic value and vital for South Australia to continue to support the needs of local communities. Through innovation, we lead, create and support a long-lasting community.​

History​​​

The White Rock Quarry in Horsnell Gully is more than 70 years old, having commenced operations in approximately 1946 to supply the Adelaide metropolitan area with aggregate material. The concrete plant located within the site has supported the construction of housing and infrastructure projects within Adelaide since it was opened by Sir Thomas Playford in 1962.

​

Heidelberg Materials has owned and operated the quarry since 2007, playing a key role in the local construction industry and in the local community, with many staff living in the district.
