Civil Drainage
Storm water management, culverts, sub-surface drainage and civil drainage systems installed correctly, the first time.
Swimming Pools
Full excavation and civil preparation for new pool installations, including soil retention and pool surround works.
Driveways
Driveway formation, base preparation, and construction for residential and rural properties across New Zealand.
Decking
Timber deck construction and outdoor structures - pergolas, platforms and multi-level entertaining areas.
Fencing
Timber post and rail fencing for residential properties, boundary definition, and site security.
Residential Drainage
Downpipe connections, soakage systems, French drains and surface water solutions for residential sites.
Hands-on.
Every time.
Helium Retaining & Construction is an owner-operated civil construction business built on engineering precision and genuine craftsmanship. When you hire us, you get the owner on the tools - not a subcontractor who has never seen your site.
We bring our own machinery to every project, which means faster turnaround, lower costs, and complete control over quality from excavation through to the finished structure. From complex retaining systems on steep residential sites to civil drainage for new developments, we deliver results that hold up for decades.
Both residential and commercial clients across New Zealand trust Helium to get difficult civil work done right, on time, and on budget.
Built different.
For good reason.
Owner on Every Job
No delegating your project to whoever's available. The owner is hands-on at every site - you get experience and accountability built into every day of the build.
Experienced & Qualified
Proven expertise in retaining wall engineering, civil drainage systems and landscape structures. Built correctly - not just built quickly.
Own Equipment
We own our digger and machinery - no hire costs passed to you, no delays waiting on subcontractors. We mobilise fast and work efficiently on site.
Residential & Commercial
From challenging residential sections to larger civil and commercial projects - the same precision and professionalism on every scale of work.
