crash, runway tarmac problems and so on

Tarmac is part of Carillion, now.

No it's not:
https://www.tarmac.com/about-us/

That's a different bit of the demerged company, dealing in building
materials, rather than construction.

Indeed, but the Tarmac that exists today isn't part of Carillion.

But it doesn't maintain the tarmac on runways. I agree the branding is a
bit confusing though.
