RAAC Concrete Surveys and Reports

Ensuring the safety of structures built with Reinforced Autoclaved Aerated Concrete (RAAC) is critical to the structural integrity of your building. With over 37 years expertise in engineering surveys and reports, our tailored solutions are guaranteed to meet your needs and guide you through the challenges of RAAC.

What we do

AWA Engineers specialise in comprehensive surveys and reports for structures constructed using RAAC. Our team of skilled engineers employs proven methodologies to identify and assess the condition of RAAC structures, highlight potential issues, and recommend effective strengthening and repair strategies.

What is RAAC?

RAAC, or Reinforced Autoclaved Aerated Concrete, is a lightweight and versatile building material known for its excellent thermal insulation properties and structural strength.

This lightweight form of concrete was used in roof, floor, cladding and wall construction in the UK from the mid-1950s to the mid-1990s. RAAC has been found in a wide range of buildings, not all of which are still in the public sector.

The limited durability of RAAC roofs and other RAAC structures has long been recognised; however recent experience suggests the problem may be more serious than previously appreciated and that many building owners are not aware if it is present in their property.

Do you need a RAAC Engineer for your project?

Enlisting the expertise of a RAAC engineer is crucial when managing an existing structure. AWA Engineers offer specialised knowledge and experience in identifying and working with RAAC, ensuring that your building meets the highest standards of safety and longevity.
