Precision Wire Sawing – Hornsby

Introduction:

Perfect Concrete Care, a renowned name in the concrete cutting and drilling industry, recently undertook a challenging project in Hornsby, showcasing our expertise in wire sawing techniques. The task at hand was no ordinary feat — a 21-metre-long retaining wall with an 800mm thickness and standing at an imposing 3 metres in height needed to be expertly sectioned into 7 panels. The ultimate goal was to facilitate the removal of the wall using a 32-ton excavator.

Scope of Work:

Dimensions of the Wall: The retaining wall measured 21 metres in length, 800mm in thickness, and 3 metres in height.

Panelization: The wall had to be precisely cut into 7 panels, each measuring 3 metres by 3 metres, allowing for efficient removal by the 32-ton excavator.

Key Challenges:

• PFC 200 Piles: Every 2.5 metres along the wall, there were piles with PFC 200, adding complexity to the wire sawing process.
• Limited Access: The height of the wall posed a challenge as there was no access available through the back of the wall.
• Uneven Surface: The wall’s uneven surface made it challenging to anchor the wire saw securely.

Solutions:

Precision in PFC 200 Cutting: To overcome the challenge of cutting through PFC 200 piles every 2.5 metres, Perfect Concrete Care executed a fast and precise cutting technique. The wire saw was operated at maximum capacity, ensuring a swift and accurate cut through the challenging material.

Innovative Wire Placement:

With no access available through the back of the wall, the team ingeniously threaded the wire through a core hole, fishing it from the top of the wall back to the motor. This innovative approach ensured seamless wire placement and effective execution.

Surface Trimming:

Given the uneven surface of the retaining wall, significant time was dedicated to trimming and levelling the wall to create a flat and even surface. This meticulous preparation was crucial for securely anchoring the wire saw and achieving precise cuts.

Conclusion:

Perfect Concrete Care’s successful completion of the precision wire sawing project in Hornsby demonstrates their commitment to overcoming challenges through innovation and precision. By employing cutting-edge techniques and addressing each obstacle with expertise, the company showcased its ability to handle complex projects with finesse. This case study stands as a testament to Perfect Concrete Care’s capabilities in the concrete cutting industry, solidifying their reputation as a trusted and reliable partner for challenging projects.
