Coreworx Joint Bays

Coreworx – A name synonymous with specialty precast concrete pits and joint bays supplied to the Australian Energy, Telecommunications and Civil sectors.  Since 2010, Coreworx has been working with energy utilities and contractors to design, manufacture and supply custom precast product solutions, engineered to suit project specific requirements.

Focused on delivering high quality products through engineering know-how, Coreworx Joint Bays have earned acclaim and recognition as the leading manufacturer of large precast concrete pits, and as the go-to for high voltage (HV) custom precast joint bays.


Engineered HV and LV cable jointing pits in single and modular configurations… Coreworx precast joint bays are designed to meet the specific needs of the Energy Utilities sector.


Mascot Engineering holds a patent with the Australian Patent Office for a Segmented Underground Work Bay. The patented design was invented by Paul Fletcher, the founder of Coreworx Australia in response to clients’ needs to reduce time and disruption on construction sites building and installing high voltage joint bays for energy infrastructure.

This insight led to the development of what is known as the Coreworx segmented Joint Bay which is the preferred product for Ausgrid, Endeavour Energy, Systems Connect, Essential Energy and other providers. Whilst originally for the energy infrastructure market, the patent and design can be used by us to manufacture a stormwater drainage pit, a sewer pit, an electrical cable pit, an above ground box, a pump-out pit, valve pit, switchboard base or the like.

As specialists in the manufacture of joint bays and cable jointing pits, we have experience working with and providing to Australia’s energy providers.
