A UK First: In-Situ RAAC Repairs Using CFRP Technology

In-Situ RAAC Repairs

At Michael Aubrey Structural Engineers, we are proud to introduce a groundbreaking solution for the UK’s RAAC (Reinforced Autoclaved Aerated Concrete) crisis.

In a UK first, our team has developed and successfully delivered an in-situ repair method for RAAC panels using Carbon Fibre Reinforced Polymer (CFRP) technology – a material more commonly used in aerospace and automotive industries.

Carbon Fibre Reinforced Plastic CFRP

Until now, repairing RAAC meant expensive, disruptive demolition or full roof replacement.

By returning to first principles, our engineers have adapted CFRP to strengthen RAAC panels directly, without the need to vacate the building.

“This was uncharted territory,” says John Staves CEng FIStructE, Managing Director. “The Eurocode standards didn’t cover this solution – but through rigorous engineering, testing, and validation, we made it work.”

The benefits are clear:

  • No demolition required
  • Minimal disruption to occupants
  • Cost-effective, scalable, and safe

Already successfully implemented with Network Rail, this pioneering system gives councils, schools, hospitals, and public bodies a practical way to restore building safety without the huge cost or disruption of traditional methods.

This is engineering innovation at its best – providing real solutions for hundreds of at-risk buildings across the UK.
