Terminal 2 Multi-Storey Car Park Repairs

Bethell has significant experience in delivering structural concrete repair projects compliant with industry-recognised design standards such as BS EN 1504 for concrete repair and Eurocode 2 for structural reinforcement.
Bethell applied our high standards at Manchester Airport’s Terminal 2 Multi-Storey Car Park (T2MSCP), assessing and designing repairs to address structural defects and the required strengthening works.
To ensure compliance with established structural performance and durability requirements, externally bonded carbon fibre reinforcement was used in line with manufacturer guidelines.
Specialist interventions synonymous with our track record in structural remediation were required for the T2MSCP project. Structural defects were observed across the lower levels of the car park, and top deck beams needed strengthening to accommodate a new Meet and Greet entrance building.
Previous project knowledge was leveraged to select the most effective methods for repair and reinforcement, balancing structural integrity with the operational needs of Manchester Airport.
We applied our drainage remediation experience to rectify failures in the top deck’s surface water drainage system, which contributed to the concrete structure ongoing deterioration. This demonstrated the application of prior learning to a complex, live-environment project.
Specialist resources were carefully identified and deployed. For design, we utilised in-house structural engineers to provide detailed installation methodologies for the carbon fibre plates. These resources were complemented by independent testing laboratories for concrete sampling and analysis.
For the civils work, we allocated experienced and skilled operatives trained in concrete repair and protective coatings, managed by our dedicated airport team headed by our Contracts Manager. Bethell appointed a drainage team to remediate the top deck’s surface water management system.
The project was delivered under a detailed programme of works developed by our in-house planning team. The programme included integrating repair, strengthening, and drainage remediation activities. Risk Assessments and Method Statements (RAMS) were prepared for each work element, ensuring adherence to health, safety, and environmental standards.
Concrete repairs followed a systematic process: defective material was identified through survey results, removed, and reinstated using hand-applied repair mortar. Protective anti-carbonation coatings were applied to extend the life of repaired areas.
For strengthening, the carbon fibre plate bonding method statement specified surface preparation, adhesive application, plate positioning, curing requirements, and quality control checks embedded throughout.
To minimise disruption, drainage remediation works were planned in phases to ensure the car park remained partially operational. Documentation included daily site records, inspection reports, and client updates. This structured approach ensured the project was delivered to specification, within programme, and to the satisfaction of MAG.
