Case Studies
Concrete performance begins long before batching. Aggregate quality, grading control, fines behaviour, moisture variability, and processing methods all directly influence mix behaviour and structural performance.

Tindal RAAF Project Summary - Northern Territory, Australia
Proud to have delivered technically 50,000 m³ of 5 MPa flexural pavement concrete at Tindal, using both mobile dry‑batch and wet‑batch plants with multiple placement methods across the site.
The mix met strict RAAF airport pavement specifications—including air control, flexural strength, shrinkage limits, max temperature, and a 0.45 W/C ratio—which demanded tight thermal and moisture management in challenging Northern Territory conditions.
Through real‑time moisture testing, chilled‑water conditioning, sand fogging, and carefully managed stockpiles, we achieved consistent batching accuracy and a reliable 60 mm hand‑placed slump across all plant setups.
Tindal RAAF Ammunition Dump – Northern Territory, Australia
Tindal RAAF Ammunition Storage Project
This project was unlike any conventional concrete design challenge. Normally, we engineer mixes to increase in strength over decades, delivering structures with a 50–70 year lifespan. But this design brief flipped the script entirely.
Here, the concrete needed to perform in a controlled way during an internal explosion or external attack—imploding rather than fragmenting—to prevent high‑velocity concrete shrapnel and help contain the ammunition detonation within the structure.
A fascinating and highly specialised piece of engineering that pushed the boundaries of traditional mix‑design thinking.
Long‑Distance, Long‑Life Concrete Innovation – Alice Springs, Northern Territory, Australia
Working in Alice Springs presented a unique challenge: delivering high‑quality concrete to remote sites several hours from the nearest plant. Traditionally, crews transported dry‑blended materials and added water and admixtures on site—but missed admixtures and over‑watering often led to compromised results. The alternative—setting up mobile batch plants or using volumetric trucks—added significant cost and complexity.
To solve this, Glenn developed a “put‑to‑sleep” long‑life concrete using advanced cement‑admixture technology. This allowed fully batched wet concrete to remain dormant for 4–5 hours during transport and then re‑activate to set normally once placed.
The outcome?
✔️ Consistent, reliable performance
✔️ Fewer on‑site errors
✔️ High‑quality concrete delivered across vast remote regions
A great example of how innovative mix design can solve real‑world logistical challenges in Australia’s most remote environments.
Tugun Bypass Tunnel – Innovative Long‑Life Piling Mix – Gold Coast, Australia
A key challenge on the Tugun Bypass Tunnel project was the constant interruption of piling operations due to nearby airport flight schedules. With aircraft landing and take‑off windows dictating when piling rigs and cranes could operate, productivity and sequencing became major hurdles.
To overcome this, we developed a specialised long‑life piling mix that could be “put to sleep” for up to 8 hours, yet remain fluid enough to allow steel cage insertion 8 hours after placement.
This mix design gave the contractor the flexibility to drill piles and place cages around airport operations—maximising productivity, reducing downtime, and maintaining full structural integrity.
A great example of how tailored concrete technology can solve complex construction and scheduling challenges.
Townsville Bank Vault – Super‑Workable Concrete Innovation – Far North Queensland, Australia
This project involved the expansion of a shopping centre in central Townsville, which included upgrading a bank—complete with a new vault. To support the vault, the engineer planned to thicken the existing carpark slab from underneath by coring holes every metre and injecting concrete while vibrating.
Rather than rely on a slow, messy, and inconsistent process, Glenn proposed a super‑workable 10 mm concrete mix designed to flow easily through 100 mm core holes. One Saturday morning, a pump fitting was bolted onto the first hole and began pumping. As each section filled, we simply moved hole to hole until the final one erupted like a controlled volcano—proof the entire cavity was full.
The result?
✔️ A flawless, glass‑smooth underside finish
✔️ Faster construction
✔️ A safer, more reliable solution for a heavily loaded vault structure
A great example of how the right concrete technology can turn a challenging engineering detail into a clean, efficient outcome.
Q1 Gold Coast – High‑Rise Concrete Engineering at a New Scale – Gold Coast, Queensland, Australia
Back in 2002–2005, the Q1 project set a new benchmark—becoming the tallest residential building in the Southern Hemisphere at the time. Designing the concrete mixes for a 230‑metre tower was a completely different challenge compared to the typical 40‑storey Gold Coast projects of the era.
Q1 required high‑performance, highly workable mixes, including:
• 65 MPa / 100MPa 200 mm slump for piles and early columns
• 22 MPa, 4‑day post‑tension podium slab spanning two city blocks and desks
• 65 MPa /80MPa core walls and 50 MPa / 180 mm slump columns up the tower
Concrete strengths were then strategically reduced as the building rose and load paths changed.
One of the biggest challenges? Pumping concrete 230 m vertically.
Factors to be accounted for:
✔️ Major slump loss through pump friction and heat
✔️ Seasonal temperature swings over the 3‑year build
✔️ High‑altitude wind effects on placement and curing
✔️ Precision batching and tight admixture dosing to maintain performance
By the time concrete reached the top decks, a 230 mm slump at the pump would arrive as 120 mm at placement—something which had to be designed for from the start.
A unique operational hurdle was pump blowback: after every top‑floor pour, 8 m³ of concrete returned down the line to a waiting agitator for disposal.
Another factor the mix designs had to absorb.
Q1 was a landmark project that pushed concrete technology, pumping logistics, and mix design thinking well beyond the standard practice of the time.
A great experience to be part of.
