Day 15 - 25th of Feb - the slab has been laid. On one of the hottest day's this summer (38 Deg) we got to the block at around 8.00am to find a convoy of trucks at our site with a concrete pump dumping cement. We were a little concerned that the heat may be too much, but trusted it to the professionals. They started around 6.30 and were done by Midday.
