Porcelain Patio - Getting myself in knots

    The internet is a great and terrible thing!!!

    I’m planning on doing the patio myself - all the time of the world, not afraid of hard work - but I’m getting myself in knots with the sub bases for the porcelain patio.

    What I’ve researched is that you need 100mm of Type 1; 50mm of a 1:12 lean mix - whacked; 30mm sand:cement 1:4; and 20mm flag. The Paving Expert and Greentop Landscape talk about how porcelain must not be laid on an unbound/flexible sub base - hence the weak lean mix. This makes a lot of sense to me. But on the brockstone YouTube he uses a dry mix to bring up levels if needed. And I really like that guy and the stuff that they do.

    The problem is that I have 160sq m of patio to lay; and my side access is the size of a wheelie bin. That’s 35 tonne of Type 1 to bring in by hand - which is fine to do.

    My question is really about the 50mm 1:12 lean mix. If I lay that myself I’d need about 8 m3. And if I’m gonna do that I might as well get concrete pumped in and lay the porcelain on with adhesive.

    Any advice? Appreciate everyone taking the time to read this. Thank you.

    Can u offer any help


    The concrete footpath looks old

    Have you excavated the ground to allow for all this? On settled ground a patio needs nothing more than a two inch bed of mortar.

    Just a word of caution, cutting porcelain slabs, if there's a lot, need consideration.
