Penetron played a key role in the successful delivery of the $632 million Campbelltown Hospital redevelopment, partnering with Traino Group and CPB Contractors to supply advanced waterproofing solutions for the 12-storey Clinical Services Building. The project, which began in December 2019, required careful attention to structural integrity and waterproofing, especially for the extensive concrete elements across the site. Penetron’s products were crucial in protecting the building’s below-ground structures, exposed terraces, and the roof slabs, including the helipad.
To meet the project’s rigorous demands, Penetron ADMIX was added to the concrete mix to provide permanent waterproofing for approximately 35,000m³ of concrete. In addition, Hydrostop CB and Penebar SW55 waterstops were used to seal critical construction joints. These advanced products ensured that the structure would remain durable and leak-free for the long term, especially in areas vulnerable to water exposure, such as the exposed roof slabs and the helipad.
The final major milestone was the completion of the helipad in February 2021, which was treated with Penetron ADMIX, marking the successful conclusion of the major concrete placement phase. By partnering with Penetron, the project team was able to deliver the Campbelltown Hospital redevelopment on time, ensuring structural reliability and waterproofing protection for this vital public infrastructure.

The Fontana Drive Bridge in Box Hill is a recently completed bridge project that boasts a 100-year design life. This is a significant achievement in the field of bridge engineering, as it ensures the safety and longevity of the structure for future generations.
The bridge’s retaining walls, which consist of prestressed beams spanning across a river, were heavily reinforced. However, due to issues with vibration and compaction during the construction process, the concrete showed voids and honeycombing throughout the walls. This raised concerns with the council, contractor, and consulting engineers regarding the structural integrity of the bridge.
The team responsible for the project took swift action to address these concerns, putting people’s safety first. Our National Technical Manager “Hacene Baleh” personally inspected the site thoroughly and wrote a detailed full specification proposal on how to remediate the wall, both deep inside the concrete and on the surface. The proposed methods included the use of PENETRON, PENETRON CR-90, PENESEAL PRO RTU, and PENEGUARD. The results of these efforts were outstanding, and the bridge was approved for the intended 100-year design life.
In conclusion, the Fontana Drive Bridge in Box Hill serves as a shining example of the lengths that can be taken to ensure the safety and longevity of a bridge. The 100-year design life of this bridge demonstrates the effectiveness of the methods used to remediate the structure. Furthermore, the efforts of the team responsible for the project serve as a testament to the importance of collaboration, paying attention to detail, in the field of bridge engineering.
The Fairfax Track Viewing Platforms footprint spans the cliff edge along the Fairfax Walk, which is nestled within the North Head Sanctuary – a place of significance for the Traditional Owners, the Gayamagal People.
To mitigate the risks of potential cliff falls and the damage caused by recent bushfires, the new viewing platforms have been relocated to better respond to the unique characteristics of the headland and provide a safer, more enjoyable viewing experience all year-round. Two new lookouts, the Yiningma Lookout to the North provides a vantage point to look back at the cliff face and breathtaking views to the horizon that are perfect for whale watching; the Burragula Lookout to the South allows for panoramic views of Sydney harbour, creating the ideal spot for events like the Sydney to Hobart Yacht Race, or simply, to watch the sun go down.
Glascott Landscape and Civil Sydney worked carefully and respectfully to configure the large sandstone blocks, pavers and concrete delivery into the desired vision at this well-visited destination. Due to the nature of the location, with elevated headland fully exposed to the elements and limited access for moving materials in and out of site, the team is working diligently through the constraints to deliver on a highly technical specification. Each element was carefully crafted to a high quality and shaped into the design intent for this significant landmark and tourist destination.
Penetron Admix was chosen to provide the ultimate durable mix for this extremely exposed position. With the location of the viewing platform susceptible to the extreme and rugged weather, including waterborne chemicals and salts from the ocean, Penetron Admix is proven to optimize concrete for long term durability. Penetron Australia worked closely with the onsite team Glascott Landscape and Civil, concrete suppliers Holcim and structural consultants SDA Structures to deliver the main structure and decorative specialty Hocim Geostone topping slabs.
In 2018, Laing O’Rourke was awarded a $955 million contract to transform Sydney’s Central Station, delivering new Sydney Metro platforms beneath the station and an extensive pedestrian concourse, known as Central Walk. The project was completed in 2023 ahead of metro services starting in 2024.
Penetron Australia is proud to have played a vital contribution to the construction of this milestone infrastructure project. With partners Laing O’Rourke and Holcim, we were involved from the outset, detailing the capping beam with Penetron products.
The opening of this 80-metre-long concourse was one of the major Sydney Metro upgrades to Australia’s busiest railway station.
