We originally intended that the concreting boys would do their magic on July 10th - the day after the screw piles were due to go in.
However, the fact that the required torques were not achieved until extensions were fabricated and installed - delayed attempts at the slab pour until early August
By now, the beautiful, fine weather we had been experiencing in July, was long gone.
Due to constant rain - they had a lot of trouble getting even this far.
This slab is very strongly reinforced to sit on its four screw piles, take the weight of a full tank of water, and its load from the house above - all without relying on support from the sand base that it was cast on.
Because the slab is sitting on 50mm of sand and then impermeable clay - it is no surprise that you can see pools of water sitting around its edges
We solved this problem a little later on by surrounding it with ag pipe (socked) leading in to a sump with a submersible pump.
It was touch and go getting this slab cast between rain showers - so Gavin headed off to some other jobs for a week or two before coming back for the main slab
