First DH built a wall 1 block high all round to stop rain water coming off the hill at the back and into the shed.
Next the cement mixer arrived and DH and DS got their wheel barrows into action.
Then the concrete needed tamping down to remove any air bubbles which would have left holes when the concrete dried.
Between them they shifted 2 1/2 cubic metres of ready-mix concrete!!
I made cups of tea : )
