We are using a concrete pump to get the concrete to where it needs to be.  The pump is much bigger than I thought and I can only imagine what the neighbours think!

It will take around 20 cubic meters of concrete. This equates to 3 concrete mixers full of concrete.

The concrete is pumped from the concrete mixer and using a large boom arm is deposited in the correct place.

The concrete is pumped into each of the rooms. One by one. It is levelled then by hand.

The concrete pump puts the concrete in roughly the right place, but will still rely on old fashioned manpower to get to exactly the right level.

Each of the rooms is filled to the top of the concrete blocks and a steel paddle is used to flatten and level the concrete.
