The City Rail Link is the largest transport infrastructure project ever to be undertaken in New Zealand.
The CRL is a 3.45km twin-tunnel underground rail link up to 42 metres below the city centre, transforming the downtown Britomart Transport Centre into a two-way through-station that better connects the city’s rail network.
Sika Technology is proud to have been a key supplier of this critical infrastructure for New Zealand’s future.

Engineering Challenge
Chorus and JFC Civils approached Sika to develop a lightweight Roadway Infill Paver Access Cover. The current covers tend to seize shut and require specialised equipment for opening and closing.
JFC, a civil contractor charged with installation works, was keen to introduce an advanced solution. Chorus, a telecommunication infrastructure owner/operator and a long-time user of Sika’s product line, supported Sika in obtaining Engineers and Auckland City Council approvals.
As a utility service provider, Chorus wanted to evolve its asset with specific consideration to OH & S and operational efficiency.
An access cover filled with heavy granite pavers must remain lightweight for manual operational use.

- Security is with an Allen key driving a quarter-turn latch.
- Sika’s lightweight design makes for efficient and safe logistics requiring no heavy lifting equipment at installation and operational stages.
