Hydro Excavation
Potholing and exposing services, Trenching (Slot Trenching), Excavation Under and Around Sensitive Infrastructure
Over two decades working on Canterbury’s utility network.
WICS is a Christchurch-based company specialising in hydro excavation and underground water infrastructure. Our business is divided into two main brands, WICS Hydro and WICS Water.
Our hydro excavation truck allows us to safely expose live gas pipes, power cables, fibre networks, water mains and sewer lines with minimal disruption.
What sets us apart is our background in certified water and drainage installation. We are CCC approved water installers and certified drainlayers, meaning we not only expose services — we understand how they are built, connected and protected.
This dual capability allows us to deliver safer excavation, smarter installations and better long-term outcomes for our clients.
