West Ruislip concrete breaking trials

From HS2:

At the West Ruislip site, we will be carrying out a 5-day trial of a machine that breaks down concrete into smaller reusable parts.

If this trial is successful, it will mean that the number of lorry movements required to transport concrete to and from site will be reduced and will remove a significant number of lorries from local roads.
