First came to light when they first used it. Apparently everyone in civil engineering knew it was only good for 35 years. The romans managed to build stuff that still stands 2000 years later, now we are building things with less than 50 years life span.
And one party had a Building Schools for the Future program. It was ill-conceived and highly inefficient but at least it was a program.
There's concrete buildings in the UK that are over 200 years old, including one on the middle of the North Sea, this is a specific light weight concrete developed for flat rooves that's apparently failing.
My point is that they knew this stuff had a short life span when they first used it. Therefore it should come as no surprise.
The issue is that it’s been swept under the carpet for so long, not that no one knew about it. By successive Governments.
Been getting discussed by people who could have got on and solved it, if the funding had been made available, for many years.
Jaz bar opened after taking over Kyber restaurant, a few years later the space above it was converted to apartments. The knobs that moved to them then complained to the council about the loud music from Jaz Bar, enforcement officers told them to turn the music down. The views expressed in my posts are not necessarily mine.
