As was stated in response to a previous question on this subject (160054) from the Honourable Member in July 2018, Bentonite is proposed to be used in the construction of the diaphragm walls for the 5 intermediate shafts in the Chilterns. If necessary, and only when the Environment Agency is satisfied with HS2 Ltd’s final approach, Bentonite may be used in other locations to minimise the impact of tunnelling on existing infrastructure.
