TLDR: Efficient ways to concrete cavity is ready mix possible?
Architect has specified a standard cavity construction from footing to DPC, this obviously needs to be filled with concrete to 225mm below FFL.
After some rough calcs the concrete will be ~6 m^3. Although possible, it is unreasonable and inefficient to use a site mixer and wheel barrow.
So just wondering if anyone has any experience trying ready mix and potentially pumping, I'm aware of the mix design being lean compared to standard ready mixes. Or any other techniques to speed up the process.
The build has already commenced so no turning back now
Thanks in advance
