Our drainage team has been working hard in Mount Albert, and the shared photos are just a small snapshot of the complex job they wrapped up. What looks straightforward from above is the result of careful planning, technical skill, and a coordinated effort across multiple teams.

Drainage project key steps:

• We excavated for a 1800mm wide concrete chamber.
• Used the rock breaker to break up magma.
• Stepped down the sides to maintain safety and prevent collapse as the excavation exceeded 1.5 meters.
• Levelled the base and carefully lowered the chamber into place with the help of Hirepool.
• Completed three 200mm concrete cores to create the required openings.
• Intorock Drilling Ltd thrusted three holes and executed a thorough water test to ensure the required flow rate for the soakage test.
• Finally, the lid was placed and the area was backfilled and compacted.

A big thank you goes out to Origin Build for the smooth collaboration and for being great project managers!
