Working within a tunnel environment presents unique demands for fire protection and material performance. Solutions must withstand extreme conditions, provide long-term durability, and meet rigorous compliance standards. As part of the wider METRONET Thornlie–Cockburn Link, the Kenwick Tunnel upgrade also needed to align seamlessly with a complex, multi-stakeholder infrastructure program, ensuring consistency and reliability across the network.

To address these challenges, Progressive Materials specified and supplied PROMATECT® H – a high-performance, fire-resistant board proven in tunnel applications worldwide. Its durability, non-combustibility, and compliance with international standards ensured the upgraded tunnel met current safety benchmarks while providing confidence in long-term performance. The high-quality installation, ensured precision, efficiency, and minimal disruption, helping bring the tunnel in line with modern safety expectations.

The revitalised Kenwick Tunnel now combines robust fire safety with proven material performance, ensuring it is prepared for the future demands of Perth’s growing transport network.
