How Our Qualified Structural Engineers Can Help You
We provide a comprehensive service to help you identify RAAC in your building and specify effective repair solutions. Here’s how we support building owners, local authorities, and organisations extend the life of buildings;
RAAC Identification and Surveys
- Conduct thorough visual inspections and structural assessments to identify the presence of RAAC in your building.
- Use advanced techniques to assess the condition of RAAC panels, including signs of cracking, deflection, or moisture damage.
- Document findings with detailed reports and photographs, giving you a clear understanding of the risks.
Next Steps Once RAAC is confirmed
- Risk Assessment to determine immediate safety response for users of the building
- Structural Integrity Assessments
- Remedial Options – Replace or Repair
- Repair and reinforcement solutions
Structural Integrity Assessments
- Evaluate the load-bearing capacity of RAAC elements to determine their ability to support current and future loads.
- Identify areas where RAAC has deteriorated to the point of requiring immediate attention.
Repair and Reinforcement Specifications
- Provide tailored recommendations for repairing or reinforcing RAAC elements, ensuring long-term structural stability.
- Specify modern materials and techniques, such as Carbon Fibre Reinforced Polymers (CFRP), to strengthen and extend the lifespan of RAAC components.
Compliance with Standards
- Ensure all assessments and repair specifications meet the latest building regulations and safety standards.
- Help you navigate compliance requirements, providing peace of mind for building owners and stakeholders.
Collaboration with Your Team
- Work closely with contractors, architects, and facilities managers to ensure seamless implementation of repair solutions.
- Provide ongoing support and advice throughout the remediation process.

What is RAAC and Why is it a Concern?

RAAC, a lightweight concrete material used in buildings from the 1960s to the 1980s, has been found to deteriorate over time, posing significant risks to structural integrity. Commonly used in roof slabs, floor panels, and walls, RAAC is prone to:
Cracking and Deflection
Over time, RAAC can lose its strength and stiffness, leading to cracks and sagging.
Moisture Absorption
RAAC is highly porous, making it susceptible to water ingress, which accelerates degradation, failing to protect reinforcement in the way normal weight concrete does.
Installation Defects
Some problems have been attributed to manufacture and installation defects.
Structural Failure
If left unchecked, deteriorated RAAC can lead to catastrophic failures, endangering occupants and property.
