Refurbishment work continues across the EDF Energy fleet of power stations this summer.

Operatives are currently on site at Hinkley Power Station completing the 2018 Concrete Spalling Remediation Programme.

The work continues from last year when over ten tonne of specialist repair mortars and structural strengthening products were used to rectify the degradation of reinforced concrete at various areas across the station.

Repair work will focus on areas of concern that may impact plant reliability. A range of Flexcrete repair materials have been specified.

Steel reinforcement protector 841 will be used for corrosion prevention, ahead of repair mortar application. The dense matrix of the coating will protect the steel from aggressive acid gases, moisture and chlorides.

Monomix HD will be used for the structural repair, rendering and profiling of surfaces.  High bond strength exceeds tensile strength of concrete, thus ensuring monolithic performance of the repair.

Cementitious coating 851 will be installed to enhance the durability of concrete. The surface protection system protects against ingress and has high resistance to carbon dioxide gas and chloride ions.

The scope of work is also set to include structural strengthening through carbon fibre wrapping, and sprayed concrete.

Work is also scheduled to start at Hartlepool Power Station next week. Concrete refurbishment will be undertaken in the CW Forebay, and basement leak sealing in turbine hall basement.
