Overview

Saving the Mining Industry Time & Money

A proudly Australian-owned innovator Since 1989 and with operations throughout Australasia we specialise in providing tailored solutions for void filling, re-levelling, and ground improvement.

Some of the more common applications for the remediation of mine assets are:

  • Raising subsided stacker-reclaimer rails to re-establish design levels.
  • Providing targeted ground improvement to weak sub-grade soils beneath production machinery platforms.
  • Filling of voids directly beneath roadway or workshop slabs to reconfirm support and limit deflection and deterioration.
  • Injection of Rail formation.

To address these technical challenges, we have developed cutting-edge technologies like Teretek®, JOG, & Terefil® which are leaders in their class.

 

Minimal disruption to the mining operations, whilst prioritising safety.
