Victoria line suspended - concrete flood 23 Jan 2014

I'm afraid I don't know how or the checks before hand. Someone more knowledgeable in that area might be able to answer those questions. I'd imagine they'd try to remove as much wet concrete as possible whilst they could.

From what I've read they used sugar to keep it from setting. Apparently that delays the chemical reaction and if used enough it'll keep it from ever setting. I can imagine that the local supermarket has run out of sugar now.

The Telegraph made a good article over the technic used to solve the problem.

Good thing we could shovel the concrete away instead of pickaxe it out.
