?Can-do? attitude crushes the competition

With a small team of 15 employees, this privately owned company, strategically based in the Hunter Valley, has mobilised equipment and personnel as far south as Canberra, west of NSW to Narrabri and as far north as Moranbah in Queensland. Not content with providing a service close to home, CZL Group is prepared to travel anywhere to assist its customers. It is well equipped to crush and screen different products, including aggregates, roadbase, stemming and ballast.

The contract crusher has worked for numerous mining, quarrying and Tier 1 construction companies, and some of the smallest regional councils. These include Rio Tinto, Xstrata Coal, Peabody, Vale Australia, Anglo American, Thiess, United Colliery, Hanon Heidelberg Cement, Boral, Holcim Australia, John Holland, Baulderstone, CPB Contractors, Ward Civil, Downer, Tema Engineers, Enerflex, Jemena NSW, National Parks and Wildlife Service, Singleton Council and Lake Macquarie Council. Many of these have been repeat clients.

One satisfied repeat client has been Lend Lease Engineering (formerly Abigroup). CZL Group’s first contract with Abigroup was hourly hire and earthworks on the Bulahdelah Bypass in 2005.

After completing jobs to crush roadbase and general fill for Abigroup’s Greta Rail and Hunter Valley Expressway projects, CZL Group was offered the opportunity to work on the RMS Pacific Highway upgrade.

The RMS upgrade of the Pacific Highway will provide a four lane divided road from Hexham to Tweed Heads. Upgrading started in 1996, and 2020 has been identified as the targeted completion. In 2014 tender invitations from Lend Lease Engineering were circulated to all major contractors to bid for the crushing and screening contract producing roadbase material for the Pacific Highway Upgrade – Nambucca Heads to Urunga section.

Lend Lease awarded the crushing and screening contract to CZL Group.

“All the tender quotes were close; our bid was right on the money,” CZL Group’s managing director Rob Grisinger said.


“It came down to our reliability and ability to produce a quality product. We have worked closely with Lend Lease on other projects. Our reputation and reliability is what advantages us in the repeat business.”

Commencing work on this section of the highway in May 2014, CZL Group set up a crushing train to begin the mammoth task of crushing and screening the required roadbase.

Starting on-site with an excavator, a loader, a dozer, an impact crusher and a scalper steadily producing roadbase, by September 2014 CZL Group had on-site four crushing trains (of 20 or more machines), now with jaw and cone crusher configuration, producing about 40,000 tonnes per week, operating up to six days per week to produce the 2.1 million tonnes of roadbase now confirmed as crushed by CZL Group for the project.

CZL Group is still working on-site, hiring out its 20,000-litre water cart for the duration of this section of the project.

In April 2015 Lend Lease again contracted CZL Group on the Pacific Highway Upgrade Project, this time on the Oxley Highway to Kundabung section. Commencing with three machines, by October 2015 CZL Group had three crushing trains and about 15 machines on-site. To date it has produced more than 1.2 million tonnes of material.

For CZL Group to retain its client base and gain new clients and contracts, it has an extensive fleet of machines ready for any size job. Machines are MDG15 and AS4242 compliant for the mining sector, and RMS G22 compliant for roadworks. Its fleet comprises various excavators, from 25 tonnes through to 50 tonnes, Hyundai 770 and 780 loaders with Compuload scales, Caterpillar D8R dozers, Telestack TC420 conveyors, Powerscreen’s H5163 and Chieftain 2100X screens, Warrior 1800 scalpers, XH320 impact crushers, Maxtrak 1300 and 1000 cone crushers, plus Terex Pegson XR400S and Powerscreen PT400 jaw crushers.
