Concrete structure repairs
Through our existing National Grid minor civils framework, we were appointed to undertake the repairs to an existing defective high level concrete structure within the live operational substation compound.
The works were successfully completed under a client led outage on the system and the circuit was returned to operation within the client’s timeframe.
The works
- Survey of the existing reinforced concrete structure to scope the proposed works.
- Removal of loose debris from the structure via MEWP access.
- Erection of full height perimeter temporary independent scaffolding with debris netting.
- Concrete repair works including cutting and breaking out the defective concrete, preparation of the existing exposed reinforcement bars and application of concrete repair compound.
- Cleaning the existing concrete structure and applying anti-carbonation coating.
