In January 2025, a civil engineering company in Wellington, New Zealand, encountered a significant technical challenge: the removal of thick reinforced concrete walls within a hydroelectric power station undergoing renovation. Due to strict environmental regulations and the need for zero vibration near sensitive underground pipelines, they required an advanced and precise solution. Their project lead, Ethan, contacted YG Machinery for a custom wire cut concrete system.
After in-depth technical discussions—addressing factors such as dense rebar, strict environmental controls, and limited workspace—we recommended our hydraulic wire saw system equipped with high quality diamond wire. Just three weeks after delivery, Ethan reported outstanding performance, stating that the machine provided “a level of precision and efficiency unmatched by any previous equipment.”

Wire Cut Concrete’s Growing Demand in New Zealand
As New Zealand continues to upgrade its aging infrastructure—particularly in power generation, transportation, and marine sectors—there is a growing demand for precise and vibration-free concrete cutting methods. Many structures, such as hydroelectric plants, coastal retaining walls, and tunnels, require demolition or modification without affecting nearby buildings, geological formations, or environmentally sensitive zones. Traditional cutting tools often produce excessive vibrations and dust, which can compromise structural stability and violate environmental standards, especially in seismically active areas or near protected waterways.
Ethan’s team faced a critical challenge while working inside a decades-old hydro station in Wellington. The reinforced concrete walls were packed with dense rebar, and the workspace was damp and confined. Conventional cutting equipment failed to deliver clean, accurate results—and couldn’t safely operate in such moisture-rich conditions. This was where the wire cut concrete solution from YG Machinery made the difference.
How YG Solved the New Zealand Client’s Problem
The client required high-precision concrete cutting that wouldn’t disturb the station’s foundation or surrounding utility systems. With YG Machinery’s wire saw for concrete, Ethan’s team successfully:
- Performed cutting in wet and semi-submerged environments up to 50 meters deep.
- Made accurate, dust-free cuts around dense rebar without generating heat or sparks.
- Finished the job 40% faster than originally planned, thanks to efficient wire sawing.
- Reduced labor costs by 25%, as the system required only two operators to manage.
The client also highlighted the machine’s reliable performance under extreme moisture and load, noting that a European wire saw they used the previous year had struggled under similar conditions. YG’s system, in contrast, offered longer-lasting diamond wire, stable hydraulic pressure, and minimal downtime—ideal for New Zealand’s demanding infrastructure environment.
Advantages of Wire Cut Concrete
The method is widely adopted for cutting reinforced concrete in bridges, piers, tunnels, and underwater structures. Its key advantages include:
- Minimal vibration and noise, which is essential for sensitive structures.
- Unlimited cutting depth, ideal for large-scale infrastructure.
- Efficient rebar penetration, without the need for manual dismantling.
- Underwater compatibility, especially valuable for island nations like Seychelles.
- Safer working conditions, reducing risks of cracking or collapse during demolition.
This technology not only meets environmental regulations but also boosts project efficiency and safety.
Work Steps
- Pre-set cutting line:
According to the construction requirements, determine the cutting surface and cutting direction, and mark the cutting line. - Installation of guide wheel system:
Set up several guide wheels, so that the wire rope can fit the cutting surface, and adjust the tension at the same time. - Thread in the diamond wire rope:
Lead the wire rope out from the main machine, wrap it around the guide wheels and cutting area to form a closed ring. - Tension and start cutting:
start the motor or hydraulic motor, the wire rope runs at 20-30 meters/second to start cutting operation. - Continuous water supply to reduce temperature and dust:
Continuous water spraying during the cutting process prevents overheating and reduces dust to protect the wire rope and equipment. - Completion of cutting and dismantling:
After the cutting is finished, stop the equipment and dismantle the wire rope for structural transfer or subsequent construction.
