TNE Civil delivered concrete repairs to the Kenwick Tunnel as part of the Thornlie–Cockburn Link.

Constructed nearly 20 years earlier, the tunnel required revitalisation to meet current standards before becoming part of Perth’s first east–west cross-line rail connection.

TNE Civil completed a controlled programme of precision crack repairs, covering the location and identification of defects through to injection, monitoring and final sealing. The works support the tunnel’s long-term structural durability.
