It’s hard to believe we’re already approaching the halfway point of the year. As the mornings and evenings grow colder, we’re grateful for the recent spell of clear, settled weather — ideal conditions for progressing with external works across our active projects. 

At Sansom, we’re proud of the diverse range of concrete repair and maintenance services we offer, but one area where we have built a particularly strong reputation is in tunnel infrastructure. 

To date, we’ve successfully delivered waterproofing solutions for 15 new tunnels throughout New Zealand, establishing ourselves as a trusted partner for both public and private sector clients. Our tunnel portfolio includes some of the country’s most high-profile and challenging infrastructure projects, such as Auckland’s Victoria Park Tunnel, Waterview Tunnel, and City Rail Link (CRL), which we’re proud to have completed waterproofing for 90% of the entire CRL, the largest transport project ever undertaken in New Zealand.
