With a reputation for precision, innovation, and delivery under pressure, CF Group has cemented its status as a leader in shoring and foundation systems across Australia. Specialising in cutting-edge techniques like CSM (Cutter Soil Mixing), diaphragm walls, secant piles, and sheet piling, the company offers full design and construct services tailored to complex geotechnical environments.

Construction Manager Murat Cobanoglu describes CF Group as a specialist team of problem-solvers who thrive on engineering challenges that others might avoid. This spirit has been key to their success on a diverse range of high-profile infrastructure and residential developments.

A flagship development for the Gold Coast, Iconica Surfers Paradise presented both geographic and engineering extremes. Located just metres from the ocean, the project required the installation of an 800mm-thick CSM shoring wall to support a five-level basement—all while navigating high water pressure and neighbouring infrastructure like the light rail.

“This was our first time using a CSM system in Queensland on this scale,” explains Murat. “We had to win over the consultants and demonstrate the benefits—particularly the water-cutoff capabilities and soil stabilisation of CSM.”

CF Group also introduced high-tension anchor bars (rated up to 100 tonnes) to retain the structure, a Queensland first. Where anchoring wasn’t possible due to sensitive structures, secant buttress walls were installed instead. The complexity of the design, combined with the excavation depth and water management challenges, meant the project ran over 1.5 years—a true testament to CF Group’s engineering discipline and strategic foresight.

CF Group’s work at the Cypress Site marked a national milestone. The company executed Australia’s deepest sea assembly, reaching depths of up to 40m. This three-level basement required the development of a hybrid CSM system that effectively operated like a diaphragm wall—filled with concrete and steel reinforcement to form structural buttresses.

“We had to rethink traditional methods,” said Murat. “Each panel took two days and required precise coordination. This wasn’t just about drilling and pouring—it was about matching grout mixes, cage installation, and alignment of coupling for slab connection.”
