The powerful and productive DXB breakers from Doosan are said to suit a wide array of applications such as tunneling, secondary reduction, primary winning and demolition.

New tunnelling technology from BASF has helped cut construction time on a major tunnel project in Australia. The system has been used to speed waterproofing, an important point as the link runs underneath one of Australia's major rivers.

As engineers write tighter and tighter specifications for grouting, so equipment manufacturers must develop solutions which can help contractors meet those specifications, and prove that they have met them Atlas Copco's new mobile grouting system, Unigrout Smart A, has been designed to do just that: it can mix, pump, monitor, log and control flow and pressure precisely. The control system allows on site mixing of a range of grouts as required by the project.

A new agreement between Volvo and Sweden's CeDe Group will see a new range of tunneling machines coming to the market.
