Bit worried about why there are such big gaps, one might expect
such things in crazy paving but not slabs. Is it moving due to

Scrapped out gaps that only have mud in the bottom suggest that maybe
the slaps may have just been laid straight on to bare ground.

From the sound of it they may have been poured onto bare ground, and
the gaps are where the shuttering was.
