Diacore is a Sydney-based business offering highly specialised concrete cutting, concrete sawing and core drilling services throughout Australia and the Asia Pacific region.

For more than 50 years, our business has been successfully involved in some of the most complex and logistically demanding concrete cutting projects undertaken in our region. With a focus on safe practices, we have the expertise to complete unique and complex projects within a controlled environment, against specific time, access, engineering and environmental constraints.

We offer a number of highly specialised services for clients looking for the completion of a variety of commercial and industrial projects:

• Airport Constructions & Upgrades
• Hospital & Nursing Homes
• Roads & Bridges
• Rail Tracks, Tunnels & Platforms
• Shopping Centres
• Multi Storey Works
• Industrial Shutdowns
• Dam, Water Storage & Treatment
• Demolition & Engineered Removals

• We were contracted to link a series of shopping levels on Clarence St together with a spiral staircase. Our initial plan was to cut a semi-circle for the staircase, but previous concrete works had encased the central pole. We adjusted our strategy to cut 2 semi-circles with a Circular Wire Saw and join these cuts together with Wall Saw Cuts to create a half donut shape. Ultimately this decision was advantageous as it ensured that the staircase would retain the maximum level of stability.

  The complete process required a combination of services including Circular Wire Saw cuts, Core Hole Drilling, Wall Sawing and the operation of a Gantry Crane, in order to cut out the shape and lower it down 4 meters to the level below. Afterwards our team used our Weka Hi-Frequency handsaws and ring saws to cut down the offcut blocks into manageable pieces for disposal.
