Protecting buildings
affected by RAAC

Specialist security solutions for councils, housing providers and public sector organisations managing RAAC risk.

What is RAAC?

Reinforced Autoclaved Aerated Concrete (RAAC) is a lightweight construction material widely used across the UK between the 1950s and mid-1990s, particularly in schools, hospitals and other public sector buildings.

As many of these buildings have now exceeded their intended design life, RAAC is increasingly recognised as a material that can present significant structural safety risks across the public estate. This has led to widespread inspections, building restrictions and closures across the UK.

Due to its aerated composition, RAAC has lower strength and durability than traditional reinforced concrete, making it more vulnerable to deterioration over time and, in some cases, sudden structural failure without obvious warning signs.

Industries we support

RAAC has been discovered in thousands of buildings across the UK, particularly within public sector estates constructed between the 1950s and 1990s.

RAAC Secure supports organisations responsible for securing these environments, including:

Education

Healthcare

Government Buildings

Housing

Public Infrastructure

RAAC specialist security for high-risk buildings

RAAC Secure provides specialist site security solutions designed to support organisations managing buildings affected by RAAC-related structural risks.

Where buildings are closed, partially evacuated or access is restricted during inspections and remediation works, maintaining control of the site becomes critical to protect public safety, meet compliance requirements and fulfil duty of care obligations.

Our solutions enable organisations to secure vulnerable buildings and surrounding areas, ensuring controlled access and continuous oversight while engineers, surveyors and contractors carry out essential structural assessments and remedial works.

AI-powered monitored surveillance

Perimeter security systems

Rapid deployment CCTV towers

Remote monitoring and alerts

Managing risk when buildings become unsafe

When RAAC is identified, public sector organisations must act quickly to restrict access, manage safety risks and maintain control of affected buildings.

During this time, sites can quickly become vulnerable to:

RAAC Secure provides external, non-intrusive security solutions that can be deployed rapidly without reliance on the building structure itself.
This ensures sites remain secure while engineers, surveyors and contractors carry out essential safety and remediation work.
