Porcelain Patio advice

[Oxdale]

After some advice please - My builder has a laid a new porcelain patio, on inspection,

 

1. they have laid a 7cm MOT 1 sub base and 6cm sharp sand and cement base, is that sufficient?

 

2. On some areas of the patio, I have 10cm x 60cm porcelain slips on the outside of my patio with a 9cm sharp sand and cement laid on mud ( no sub base). My turf buts directly up to this. Am I likely to have problems with this?

 

thanks

130mm prep under the main tile sounds ok to me, but it's a complete unknown tbh as the underlaying ground will dictate if this should have been tiled over a concrete slab, or just whacked sub-base, or other.

 

Laying the perimeter ribbon tile on to mud doesn't sound like it'll last one winter tbh.... I would have expected the sub base to extend out past the ribbon, by a good 200mm or more, and then a sand and cement haunch to be used to tie in with the same wet course of bed used to set the tiles in (so these were one wet mix vs two sat alongside each other). I think I'd be asking for this to be done again, peeling the turf back to do so, but it depends what you agreed or didn't agree with the landscapers.
