Another Successful RAAC Concrete Repair Project Completed for Network Rail

At Structural Repairs Ltd, we’re proud to announce the successful completion of another critical RAAC (Reinforced Autoclaved Aerated Concrete) repair project, this time on essential infrastructure for Network Rail.

This project highlights our expertise in identifying, analysing, and repairing RAAC defects using our proprietary Regrid® structural strengthening system — delivering permanent remediation with minimal disruption.

RAAC Defects Found on Network Rail Infrastructure

During a detailed structural assessment, RAAC planks were found to have multiple structural defects, posing a potential risk to the integrity of Network Rail’s infrastructure. These defects included:

• Cracks and spalling on the soffits
• Signs of reinforcement corrosion
• Compromised load-bearing capacity

Given the location and importance of the asset, a rapid, accurate and long-lasting solution was required.

Advanced Scanning & Defect Mapping

Before commencing any remedial work, our expert engineering team conducted non-invasive scanning and structural analysis of all suspect RAAC planks using:

• Ground Penetrating Radar (GPR)
• Ultrasonic testing
• Surface and internal defect mapping

This allowed us to pinpoint areas of concern, assess structural risk, and develop a targeted repair strategy that ensured safety and compliance.

Structural Repairs Using Regrid® Technology

Once defects were identified, we deployed our advanced Regrid® solution — a bespoke, lightweight structural reinforcement system designed specifically for RAAC remediation.

Key benefits of the Regrid system:

• Adds strength without the need for plank replacement
• Lightweight and ideal for overhead structures
• Fast installation with minimal operational disruption
• Cost-effective and long-lasting

The result? All RAAC planks were fully remediated, defects rectified, and the structure now meets all required safety and performance standards.

Project Success in Pictures

Our photographic records show the extent of original damage and the high-quality finish after Regrid strengthening. These visual outcomes reinforce the success of this project and demonstrate the capabilities of our solutions in real-world, safety-critical environments.
