Prestressed Concrete Products

Nelmac own and operate its own precast yard capable of manufacturing a range of prestressed products and is prequalified to CC level with the RMS for the manufacture of:

  • T Beams
  • T Roff (with Nelmac boasting the manufacturing of the first T Roff beams ever used in Australia for a bridge over the Murrumbidgee River for the Wagga Wagga City Council)
  • Prestressed Concrete Slabs
  • Prestressed Concrete Piles
  • Precast Concrete Piles
  • Concrete Slabs for smaller scale bridges


Nelmac owns and operates its own fleet of piling equipment with its pile driving procedures allowing the rig to be placed 6 metres from centreline of the pile therefore, minimising the risks associated with unstable materials around piling site.

Nelmac's preferred method for pile driving over waterways is through the use of temporary bridging. This in turn reduces the environment impact on waterways, requires minimal (if any) backfilling of waterways and minimal disturbance of surrounding banks.
