A dangerous concrete prone to sudden crumbling with age has not been found in any States building, however the States Property Unit is continuing to carry out checks across its estate.
It was recently revealed that Reinforced Autoclaved Aerated Concrete (RAAC) had been discovered in three areas of Jersey’s hospital.
It follows a national story where RAAC was discovered in hundreds of schools across the UK.
A Freedom of Information request in Guernsey has since confirmed that no States owned school buildings contain RAAC in the island.
The States Property Unit has since told Express that RAAC hasn’t been identified in any States building so far either.
A spokesperson said: “This includes the Princess Elizabeth Hospital, where we have done an initial assessment, but are carrying out a more detailed review.”
The SPU is continuing to carry out further checks across the States estate.
RAAC is an “aerated lightweight cementitious material with no coarse aggregate" used to build roofs, walls and floors, which resembles an Aero bar in structure.
The material is known to have been used in schools and colleges and other public sector buildings across the UK, dating back to the 1960s but its lifespan is known to be around 30 years. The structure is reported to become less stable as it ages.
The concrete is unstable because the air pockets inside it can collapse, causing the material to crumble, severely weakening any structures in which it is present.
