With extensive underground construction and remediation expertise, our skilled team is equipped to handle the unique challenges of tunnel environments.
Sansom ensures effective waterproofing and tunnel protection using high-quality tunnel membranes and advanced installation techniques. As licensed applicators for many membrane manufacturers, we deliver proven, reliable solutions.
With a proactive approach to maintenance and a commitment to industry standards, we conduct regular inspections, implement preventive measures, and carry out necessary repairs to ensure the optimal condition and functionality of tunnels. We currently hold a number of long-term maintenance contracts.
We work for tunnel asset owners, including KiwiRail, NZTA and Watercare, repairing their existing tunnels. Each remediation project is unique, requiring tailored solutions rather than a one-size-fits-all approach.
