ours was 120 with an extra 600 for pump regardless of how much we had. we had 3 lorry loads.
they co-ordinated themselves, sent one and then the other one despatched whilst the first pouring and same for the third one as not enough room for multiple lorries
We've found, not sure why, that we've needed more for every pour than we originally thought.
First lot was mix on site, next 2 were ready mixed. There is a company near here who are slightly cheaper, but they are supplying Sizewell C build and a huge wind farm and I wasn't convinced that we would be treated seriously.
the guys were brilliant and worked really hard in 30 degree heat, anyone remember that last summer ๐
But, not perfectly level due to drying very quickly, but as we need insulation and screed for UFH it's fine.
