Pond life - just when you thought there was no more concrete ...

Finally there is a pause in the rain and the workers are back on site. They now have to cover the liner with stone to hide the blue and make it look like it is a natural feature. The challenge is how to do that without tearing the fabric. Answer: polystyrene on top of the liner then - concrete! This ought to form a base that the stone can be laid on. So back again with our old friend the cement lorry with the incredibly long delivery tube.
