In his latest student editor blog, Jonathan McDonald highlights the overlooked importance of chalk in engineering, including in key projects like the Channel Tunnel and offshore wind farms.

Construction industry research organisation Ciria has moved forward with the project to update its guidance on good practice for engineering in chalk geologies, with fundraising currently still ongoing.

High Speed 2’s Chiltern tunnels run through permeable chalk requiring extensive ground treatment. Nia Kajastie gives an update on grouting works on the tunnel cross passages.

The British Geotechnical Association has awarded the 2022 BGA Medal to the authors of a paper describing characterisation research conducted to aid the interpretation of field experiments on piles driven at the St Nicholas-at-Wade test site in the UK.

Construction industry research organisation Ciria is planning to revise its “Engineering in Chalk (C574)” good practice guide to reflect industry experience and knowledge gained over the last 20 years.

Align JV is using chalk excavated from the High Speed 2 Chiltern tunnels to create grassland habitats in the Chiltern Hills.

A British Geological Survey (BGS) led study has revealed new insights into the role of karst in the Chalk Group aquifer, which provides public water supplies to millions of people, agriculture and industry.

HS2 Ltd said it had already addressed concerns raised by the Chiltern Society that a chalk aquifer beneath Misbourne Valley in the Chilterns is “under threat” from High Speed 2 tunnelling.

HS2 Ltd will use chalk slurry from tunnel construction to form 127ha of new grasslands and woodlands around the southern portal of the High Speed 2 Chilterns tunnel.
