Concrete quality issues impact Hinkley

Parts of foundation slabs constructed at EDF’s Hinkley Point C will have to be demolished and rebuilt after strength issues were found during an inspection by project client EDF Energy.

Concrete quality has been blamed for the issue but EDF has said that only a small area – 150m3 – is affected and it will not impact on the project timeline.

The earthworks package for the project is being delivered by a joint venture of Kier and Bam Nuttall. GE has contacted both organisations for comment on the issue.

EDF has said that the problem only affects one gallery section of the 8km of tunnels and the solution will involve removing and replacing the weak area below the foundation slab.

Hinkley construction director Nigel Cann said: “We have decided to replace a small area of concrete poured as part of the work to create tunnels for the pipes and cables. This is in line with the uncompromising attitude to quality taken at the Hinkley Point C project. It is a very small proportion of the concrete poured on site so far and has no impact on the project schedule.”
