Geobear undertook a pioneering railway embankment stabilisation project in 2022.

In July 2022 Geobear designed and implemented a world first embankment stabilisation scheme on the Severn Valley Railway (NCE, September 2022). Eight months after the work began, the latest results from the project have been released. The scheme featured a Geobear…

An exploratory tunnel driven ahead of the main Brenner Base Tunnel bores through the Alps is helping contractors meet the challenges in building the world’s longest underground railway corridor.

Tunnelling through robust rock with complex fault zones – fractures between two blocks of rock – is characterising construction of the Brenner…

After years of planning wrangles, construction of the Silvertown Tunnel in east London is finally underway.

By the time Christmas arrives, contractor Riverlinx’s project manager Ivor Thomas hopes that the Herrenknecht tunnel boring machine (TBM) currently driving the Silvertown Tunnel will have passed safely under the Thames. This would be a…

Future proofed electricity infrastructure will not be the London Power Tunnels’ only legacy. The project is also setting new standards with its delivery model and equipment.

Meeting London’s future electricity demands and replacing technology that had reached the end of its life are the reasons behind National Grid’s current London…

Clay soil stabilisation and extending asset life with geopolymer.

Climate change has created a growing challenge for building and infrastructure engineers in the UK. A phenomenon known as shrink-swell in clay soils is necessitating greater consideration when managing asset life as result of climate change. Swelling pressures can cause heave while…

Concept Engineering Consultants has gained a firm foothold in the ground investigation market by taking on challenging work. Twenty five years on, the business is pursuing “purposeful growth”.

Ground investigation technology has been a fast developing part of the construction supply chain in recent years and leading players are well established…

The first real world test of a new microgravity sensor could lead to a revolution in detecting buried structures and underground hazards.

Unexpected ground conditions are still one of the biggest risks facing construction projects. But imagine a future where that danger has been accurately reduced before even a single borehole…

Geopolymer ground stabilisation is less carbon intensive than more traditional methods.

The climate emergency requires action from us all, especially the construction sector which contributes significantly to carbon emissions. Recent research by the World Resources Institute found that 76% of global emissions are a result of energy use, with the biggest…

Although spending on tunnelling projects has been high in the last decade, the supply chain is facing some major challenges as it looks to manage risk on future projects while addressing the carbon net zero challenge.

Contractors, consultants and equipment manufacturers in the tunnelling sector have showcased their advanced engineering capabilities…

A fresh approach to tunnel boring machine removal on the Sydney Metro project has helped to drive efficiencies on site, while breaking a tower crane world record in the process.

Hailed as the biggest public transport project in Australia’s history, Sydney Metro is set to revolutionise the way commuters travel across…
