Hi, a quick question for the pros: we had a terrace made of travertine installed by a company, with the slabs (30x60cm (12x24 inches)) laid on gravel. Do they now need to be brushed with quartz sand and then compacted again? Our terrace builder said this isn’t necessary and that he doesn’t have a plate compactor for such slabs anyway.
Good luck & thanks

If there are no joints at all, then from my amateur perspective, that's already a mistake. The gravel provides stability to the slabs. Due to rain and minor movements, the gravel shifts in the joints, so it needs to be refilled regularly during the first few weeks.
My neighbor told me that at his company, they only install patio slabs on gravel with a written waiver of remedial work for any settling. Because according to him, settling almost always occurs, sometimes earlier, sometimes later. We have no joints, and that is not a mistake, but actually very good.
