Well, I carefully took the shuttering off the concrete and ping pong balls to see how it looked…
… pretty bad. The surface hasn’t got as many bubbles in it as I had thought would be the case. Most of the part cut balls filled, at least in part, with concrete so there was less to fill the void and take the concrete to the top of the shuttering.
It is clear that taking the pressure off by lifting the top meant that the balls expanded and cracked the concrete into layers. However, I’ve taken the view that it can’t get much worse if I clamp everything up again while the concrete still seems soft. Maybe, just maybe, the cracks will heal over and the structure stand the forces generated when the shuttering comes off – probably that will happen in a week or so [I’ll ask Ed for guidance].
Time to something in no way related to the Trophy project. Vincent
Oh dear…. and the planning had looked so promising! Truly ugly at the moment, it has to be said….
