What is RAAC?

Reinforced Autoclaved Aerated Concrete (RAAC) is a lightweight form of precast concrete that was commonly used in the UK between the 1950s and 1990s, particularly in roofs, ceilings, walls, and floors. 

Over time, RAAC can lose structural integrity due to moisture ingress, corrosion of embedded reinforcement and age-related deterioration. As a result, many RAAC-constructed buildings now require remediation or replacement works to ensure they remain safe and compliant for continued use.

Types of RAAC Buildings

RAAC was widely used across a variety of building types, many of which are still in operation today. This includes:

  • Public buildings: offices, libraries, community centres. 
  • Public sector facilities: local authority and government buildings.
  • Schools: classrooms, sports halls and administrative blocks.
  • NHS trusts and hospitals: clinical and administrative areas. 

Many of these buildings remain in use, meaning that any fit-out works often need to be delivered within live environments. Willmott Dixon Interiors has extensive experience working in occupied or sensitive spaces, carefully planning and managing projects to maintain safety and minimise disruption. 

Removal vs. Reinforcement

When addressing RAAC, there are two primary approaches, and Willmott Dixon Interiors has the expertise to deliver either solution depending on the condition of the building and the needs of the client.

RAAC Removal

A full removal involves taking out all RAAC planks and replacing them with a new structural solution. This is best suited for:

  • Areas where RAAC is severely deteriorated
  • Projects where the long-term asset strategy favours full replacement
  • Situations where extensive refurbishment is already planned

RAAC Reinforcement

Reinforcement provides a safe, engineered solution that maintains the existing RAAC while strengthening it to modern standards. This is best suited for: 

  • Buildings where the RAAC remains structurally stable
  • Sites needing quicker, less invasive intervention
  • Live environments where minimising disruption is critical

raac funding

Government funding has been made available to support the assessment, remediation and rebuilding of RAAC-affected properties, particularly within the education and healthcare sectors.

Additional funding streams may also be available through local authorities, public sector frameworks or private investment to support the internal fit-out of buildings once structural works are complete.

Our team can advise on available funding routes and align fit-out programmes with any ongoing or planned remediation works. 

featured project: Hodge hill college

Our team delivered a fast-paced RAAC mitigation scheme at Hodge Hill College, ensuring the school could continue operating safely while essential structural, services, and fire safety upgrades were carried out.

Appointed via the Department for Education’s construction framework, we delivered urgent remedial works after RAAC was identified in the roof structure, including the design and installation of a bespoke timber lattice system to support new ceilings and services. Working in a live secondary school, we also upgraded M&E systems, fire safety provisions, internal finishes, and completed a full kitchen ceiling replacement while minimising disruption to teaching.

Project outcomes:

  • All unsafe RAAC fully mitigated, providing peace of mind for the school community
  • Enhanced fire safety measures and upgraded building services to support daily operations
  • Technically complex works delivered in a live school environment with minimal disruption
  • Continued delivery of high-priority education projects for the Department for Education
