about us

The primary activities of Conundrum Holdings are quarrying and the manufacture of pre-mixed concrete.

A family owned business born out of RF Kerr Quarries, we started operating under the Conundrum banner in 1988. Following extensive experience in various mobile crushing operations across the state, we now operate a number of fixed crushing plants at sites in metropolitan and regional Victoria.

With the acquisition of McKenzie Creek Quarrying Co. in 2006, we expanded our operations into the manufacture of pre-mixed concrete, drawing on the decades of experience from the previous owners of that business, the Langlands family.

We are committed to serving our customers as an efficient and reliable supplier of quality products and services at fair prices. Our extensive experience in the production of quarry materials, ranging from road base and sealing aggregates to rail ballast and beaching materials, and our range of pre-mixed concrete means that we can be sure to meet your specific needs.
