Introduction

Reinforced Autoclaved Aerated Concrete (RAAC) was commonly used from the 1950’s to 90’s as a lightweight construction material in schools, colleges and some public buildings.  

Understanding the challenges RAAC presents

The material was often found in flat roofs, pre-cast panels, floors and walls. The period of usage aligns with the use of asbestos. The material had a lifespan of approximately 30 years. As a result, the potential for structural failure can be reasonably expected as time goes on. Water and moisture ingress will invariably affect the integrity of any steel re-enforcement under the circumstances. The structural integrity may be affected where there has been decay at the ends of any beams / panels. RAAC products may have also been coated with other products over a period of time, such as bitumen.  

Asbestos considerations

Where RAAC is suspected to be present, a survey of the building by a structural engineer will be required to identify the risks of structural failure and building integrity. Aligned with this, any asbestos containing materials will need to be identified to ensure safe working for contractors. Reference to the asbestos register and surveys must be remembered. 

Finding solutions

Countrywide are able to offer support and advice as to how asbestos should be addressed within these buildings enabling any testing or remedial works to be undertaken. This may be in support of Rand D surveying, or for the removal of asbestos to allow other works to be carried out safely.  

Countrywide undertake asbestos removal in Liverpool, Manchester, Cheshire, Manchester and Lancashire. We work in a variety of sectors. https://countrywide-environmental.co.uk/asbestos-removal-services/

The team look to provide practical solutions to meet the scope of works whilst maintaining asbestos compliance throughout. Every project is different for large and small scale works. All areas of risk are considered to ensure the programme of work is achieved, both on time and within budget. Our team are on hand to help in balancing against planning, managing and and costing schemes. This will protect both any existing building users and any contractors working on the building for RAAC remedial works.  

Our services are quality assured to ISO9001, 14001 and 45001 for quality, environmental and safety management respectively. All works are delivered by highly competent personnel. For further information, please contact us by email admin@countrywide-environmental.co.uk or by phone on 0151 426 2110.
