      . I wonder whether these problems will ever be solved and what is the chance of multi-storey car parks being affected by similar ?  Apparently the government has been aware for some time ..........

And likely to result in another big lengthy closure for some schools, I can't see them being repaired quickly 

[Minusminnie]

My grandchildren are lucky and go to a newly built primary school. Built on local land with planning permission for some houses as well. The new school being part of the deal. The old school sold and demolished and now being developed with houses. 
Maybe one solution in some areas.

Reading some reports today, it's going to take 10 years B4 the problem is sorted.  Hospitals are affected too.

I thought crumbling concrete, or did they call it concrete cancer??, had been around for years. I'm sure I remember stories from the 90s, maybe even the 80s, about buildings being affected. I think it was tower blocks that had been built in the 60s and were deemed unsafe, so it begs the question about why these problems are now being reported.

I heard it has been used in public buildings, not just schools.  So any public building from the 50s onwards could have it. Quite scary to think they can collapse at anytime without any warning.

I agree, I didn't even listen to the story but have been unable to avoid it, it's everywhere. 

I did question that myself, why right now?

[CLKD]

Because ........ having found out that the same Company was employed to build these properties, alarms have been raised.

Concrete cancer is different to the current problem which is due to RAAC.

"Concrete cancer is caused when the steel reinforcing within a concrete slab begins to rust. As the steel rusts, it expands and displaces the surrounding concrete; causing it to become brittle and crack which exacerbates the issue. Signs of concrete cancer include: Delaminated and cracking concrete (concrete spalling)"

"What is the problem with RAAC concrete?
RAAC is not like traditional concrete in that it isn't made with aggregate. It's less durable and has a shorter lifespan of around 30-years. That's the main reason why some of it is now running the risk of failure, especially where it's not been well maintained. RAAC can be found in all building types not just schools."

[getting_old]

Thanks for the explanation. Worrying about the 30 year lifespan if it was used extensively in the 70s etc. and the buildings are still in operation.

[Limpy]

Yes Getting_old, as you say the 30 year lifespan seems to have been played down somewhat.

And of course LAs have changed over those years so the buildings probably haven't been followed through in order to consider planning for new ones.  QEII Hospital at Kings Lynn has been falling apart for years, being held up with pit props!

[CLKD]

Tnx Limpy

Lots of buildings are likely to be affected across the UK.  Many theatres included, at a time when they are struggling back from going dark during Covid 

[Sage 🍃]

Hospitals as well.

NHS trusts are told to prepare to evacuate hospitals with crumbling concrete
