Boral's three operations at Maldon, located outside Picton in the Wollondilly region of NSW, form a strategic hub for the supply of crucial building and construction materials into the greater Sydney metropolitan area.

The operations began with the opening of the Cement Works during April 1951 in response to the post-World War II building and construction boom.

With direct road (Hume Highway) and rail (Main Southern Railway) access into Sydney, the site has continuously supplied bulk and bagged cement since that time.

Until 2014, the Cement Works hosted three different kilns on-site. The kilns were used to manufacture clinker, the material which is ground to produce the 'powdered' cement as bought in hardware stores.

Since the decommissioning of Kiln 3 at the end of that year, the Cement Works has reverted to grinding clinker from the Boral Berrima Cement Works as well as imported material in its mill.

With the kiln no longer in service the associated stack, a local landmark, was demolished during 2018.

Over its life, the site has produced and ground 'grey', 'white' and 'off white' variants of clinker. Grey clinker is now the predominant form used at Maldon.

The Cement Works hosts a modern bagging facility to support dispatch of bagged cement products around the state. The facility incorporates advanced technology and robotics to assist with the speed and efficiency of supply.

Bulk cement is dispatched by trains and road tankers, both familiar sights around Maldon.

Travelling south along Maldon Bridge Road, the next of Boral's local operations is the Quarries Rail Terminal.

The Terminal was opened in 2014 as part of the greater Sydney Aggregates Project which also saw the establishment of the Boral Peppertree Quarry at Marulan South.

The Project sought to initiate a replacement hard rock resource for the now closed quarries at Emu Plains in western Sydney. These had served metropolitan building needs since the 1800s.

The main role of the Terminal is to receive trains carrying the hard rock aggregates produced at Peppertree.

From Maldon, the aggregates are dispatched by road using truck-and-dog or tipper combinations to customers across Sydney, including Boral's own concrete and asphalt plants.

Today the site supports eight employees based at the Terminal, and the seven Boral Logistics drivers attached to the facility.

The most southerly operation is the Concrete plant. The plant, originally established in the 1980s, is one of 11 making up Boral's Illawarra/Southern Highlands concrete network.

The site produces pre-mixed concrete which is sent via agitators ('concrete mixers' or 'cement trucks') to customer worksites around the network region and south-west and western Sydney.

Aggregates delivered through the Rail Terminal and cement produced at the Cement Works are used at the concrete plant to generate the site's products. Activity occurs around the Boral Maldon Operations on a 24 hour-seven day basis.

This takes place mainly at the Cement Works as the Boral Maldon Rail Terminal has some restrictions included in its planning consent.

The Concrete site normally only operates during what can be considered regular business hours.

The Terminal receives up to 1.75 million tonnes per annum of aggregates by rail from the Boral Peppertree Quarry at Marulan South.

Key processes include the release of aggregates from train wagons into the 'dump station', from where they are transferred to the aggregate handling area by covered conveyors into various product bunkers.

From the bunkers, aggregate is loaded onto road trucks by front end loaders. Trucks are checked on the weighbridge prior to leaving the Rail Terminal to ensure compliance with legal axle loads.

The Rail Terminal's approved hours of operation for site activities are:

  • Train unloading and stockpiling: Monday - Friday, 24 hours
  • Truck loading and dispatch: Monday - Saturday, 5am - 10pm
  • Maintenance: Monday - Sunday, 24 hours
