HDPE Welding on the East Coast of Australia

January and February have taken the GEM crew across some of the most iconic landscapes in the country — from the red dust of Outback Queensland to the rolling hills of South Gippsland, the quiet rural pockets of Tasmania, and sunset shifts along the Murray River.

Extrusion welding doesn’t always get the spotlight, but it’s one of the capabilities that underpins much of what we deliver at GEM Industrial.

At GEM Industrial, supporting local sport is one of the most meaningful ways we can give back to the communities that support us.

From Victoria to Western Australia and every site we touch nationwide, we’re stepping into 2026 with the same grit, precision, and pride that built GEM from the ground up.

With a major increase in project awards across Western Australia, Tasmania, Queensland and Victoria for 2026, GEM Industrial is expanding its national delivery capability. We are creating opportunities for skilled and motivated people to join an innovative Australian company at the forefront of HDPE pipeline construction.

GEM's team designed and fabricated 20 large‑bore pipe trolleys, engineered to solve a very real on‑site challenge: moving heavy pipe safely, efficiently, and without compromising material integrity.

When the first batch of pipework officially rolled out from our GEM workshop — this was a proud step that highlights both our fabrication capability and delivery strength.

Mechanical Installation of a Brand New Poly Batching Unit.
At GEM Industrial, we’re best known for our expertise in HDPE fusion welding and infrastructure delivery.

In Melbourne’s eastern suburbs, our crews are deep into a live installation where welded HDPE strings sometimes can’t be built in place.

We’re proud to announce the arrival of these massive RBT 1800 mm HDPE fittings, supplied by our trusted partner Thai-Asia P.E. Pipe Co., LTD. These fittings mark a major milestone in GEM’s capability to deliver high-volume water infrastructure at scale.

GEM Industrial recently supported an Anaerobic Cover Replacement project with a custom approach to critical sludge return and feed lines—delivered under tight timelines and complex site conditions:

Braden Wright’s Journey with GEM Industrial.
At GEM Industrial, we know that great teams aren’t built overnight — they’re forged through grit, skill, and a good dose of humour. And few people embody that spirit better than Braden Wright.

At GEM Industrial, our core expertise in HDPE welding is well-established — but this recent pilot plant installation in Gippsland highlights our broader capability in multi-material process pipework fabrication. 

Our commitment to excellence in HDPE fabrication is reinforced by rigorous destructive testing of butt welds, ensuring every joint meets the highest standards of strength, durability, and safety. 

Always proud to see our team delivering quality work on the ground. Here’s a recent field highlight from one of our crew — a great example of skill, pride, and teamwork in action. 

Early 2024, GEM Industrial enhanced its workshop capabilities by commissioning the Omisa 160 SW-S Side Fusion Machine, tailored for HDPE sidewall welding. 

Nearly 600 industry leaders, innovators, and HDPE champions came together to exchange ideas, spark collaboration, and shape the future of infrastructure

It’s been a cracking few weeks for the team at GEM Industrial, Leongatha, supporting key works across Metro Melbourne! 

When tasked with connecting into an existing water network during site establishment, GEM Industrial faced a challenge: the nearest isolation point was many hundreds of meters from the tie-in, and draining the line would chew through precious shutdown hours. 

From our beginnings in South Gippsland’s dairy industry, GEM Industrial has grown into a trusted partner for complex pipeline infrastructure projects across Australia.
