Mulgoa Quarries – Striving to meet future industry demands

Mulgoa Quarries

Mulgoa Quarries’ long history in the earthmoving industry spans generations, stretching back the better part of six decades, with the family-owned-and-operated business having built its reputation around providing clients across the Sydney metropolitan region a wide range of high-quality excavation solutions.

Over the years Mulgoa Quarries has branched out from its clay and shale quarrying roots to preside over an increasingly diversified suite of civil engineering services, with it expanding to specialise in areas including major bulk earthworks, controlled filling and remediation projects.

Co-owner Adrian Wearn, who himself has been involved in the industry for close to 40 years, told EEM that while Mulgoa Quarries has grown significantly since its establishment it has very much remained a family enterprise.

“My father started quarrying in 1964, as part of his earthmoving operations, and took over some land at Mulgoa, and then started supplying the brick industry,” Adrian explained of the business’ origins.

“I started out as an apprentice plant mechanic 39 years ago, and 37 years ago myself and four brothers took over the running of Mulgoa Quarries, while for the last 20 years, it’s just been one brother and myself running the business.”

With Adrian and brother Rob at the helm of the business, Mulgoa Quarries has since grown to employ over 110 staff, with an operating fleet spanning more than 75 items of earthmoving equipment, along with 28 truck and trailer combinations of varying payloads.

Consistent and professional operations deliver repeat business

Mulgoa Quarries caters for its clients’ wide- ranging civil engineering needs, and also offers bulk haulage and disposal, waste transport and contract quarrying services, providing selective mining and stockpiling of over 1,000,000 tonne of clay and shale per annum (it has over the years held contracts with clients including Austral Bricks, Boral Bricks and PGH Bricks & Pavers).

In addition to this, it maintains a modern fleet of high-quality earthmoving equipment for hire, decked out to tackle a broad range of tasks, from roadworks to subdivisions, mining, excavation, and building and development projects.

“Our core business is contract quarrying and stockpile management for the brick industry, providing services for a sector that is reasonably unique,” Adrian explained.

“Also, we’ve recently been doing some big quarry rehabilitation work, rehabilitating old quarries in the Western Sydney area.”

Adrian told EEM that Mulgoa Quarries prides itself on putting its clients first, with its team of highly trained specialists drawing on a wealth of knowledge in undertaking a broad range of excavation and earthmoving projects.

“I think it’s been our consistent and professional operations, running sites in a manner that clients desire, and the culture of our operators and employees to be able to provide that high level of service that gives us repeat business,” he said.

“We’re proud of the professional culture embraced by all of our staff, from general tidiness and safety onsite, to a positive can-do attitude.”

Sophisticated Liebherr R 938 G8 Crawler Excavators deliver power and comfort

Mulgoa Quarries has recently taken delivery of two Liebherr R 938 G8 crawler excavators, with Adrian noting he had long been aware of the reputation of Liebherr, one of the largest construction equipment manufacturers in the world, prior to purchasing the machines.

Adrian told EEM that in an industry that is extremely demanding day in and day out, with projects needing to be carried out efficiently and effectively, Mulgoa Quarries requires equipment that is not only durable, but also versatile and powerful, with the R 938 G8 excavators fitting the bill.

“We gave an R 938 G8 excavator a demo, and found it to be a very smooth and powerful machine,” he commented. “In addition to this, our operators can customise the machine’s functions to suit different applications, and they also provide great fuel efficiency.

“Straight away we realised that they are a very sophisticated excavator, and we also found Liebherr’s service to be very keen and prompt.”

As it stands, both of the R 938 G8 excavators have been racking up plenty of operating hours since joining Mulgoa Quarries’ fleet, having been put to work across different projects, and Adrian noted that his operators are more than happy with both the performance and comfort levels provided.

“They’re working a minimum of 50 hours a week, weather depending, across various detailed and bulk excavation applications,” he said. “And they’ve been getting great feedback from the operators, and if they’re happy operating the machines that goes a long way.

“Every indication is that we have very busy times ahead, everyone wants to do business at the moment, and we look forward to moving forward with Liebherr.”
