Advice needed by plumber

[mitzimad]

hi all new here so be gentle with me boys im a plumber and you might want plumbing advice one day,im a regular on the uk plumbers forum .Due to lack of work im doing my sons garden ive got about twelve yards of slabs to lay the area is enclosed by a 2 brick high wall on two sides and raised beds on the other two, it was grass but ive lifted the turf and top soil to a depth of 50 mm the plan is for the slabs to sit on the retaing wall and butt against the raised beds its only a patio so not load bearing
my intention is to lay concrete moulded slabs (selco patio packs ) on sharp sand wacked down and motar around the edges on the walls
its 2.3 m wide by 5 metres long what should the fall be i was going for about 25mm across the width does it need to fall lengthways as well?
what is the best way to point this ?any thing wrong with my plan ?

1:60 fall is ample
so that would be 75-80mm over 5 metres
the bedding layer should have some cement in it i use 1:5

its all on the main site mate
cheers LLL

i did read main site and that advocates just sand for patios with no sub base which i why i was confused only seen them laid on lean mix on site looks like i need a mixer as well as wacker and saw
can it fall just across the width rather than the length say 50 mm across 2.3 m

The need for a subbase depends on the ground conditions.
Can fall whichever way you want it to, as long as it doesn't hold water and isn't sloping towards the house it's good. Just make sure you don't have people walking up the path like one leg is shorter than the other :p

thanks for the advice tomorrow is the big day sand and patio slab being delivered going to try laying them on a dry mix whacked down and screeded of

[mitzimad]

well its all done now hard work but very satisfying going to add pics to the site if i can only problem is im going to have to rake out and repoint i used the semi dry method from the site but motar is very crumbly think its was due to being roasting the day i did it or possibly a bit to lean on the mix probably going to repoint it in the traaditional way cant see how to add pics here but will try to upload to diy part of site

did the whole garden decking from old paths was used to form the raised beds dug by hand probably moved 3 ton of soil from former lawn into the raised beds built deck and laid slabs on screeded bed three pallets of selcos specials in three sizes ive got one cross in the patten but this was because i was keeping 6x3s for steps used every slab bar one if i did it again id use a mixer i think some of the joins are a bit wide i should have butted slabs at the bottom as sides taper out but other than that im well pleased matierials came to 1250 which is nothing considering the size of the job no wonder all you groundwork blokes drive range rovers" the pictures are before i raked out the brushed in pointing it actually looks much better now ive hand pointed it thanks to all for advice and for whats probably the best trade web site ive come across

Get plenty of spam already Dave. It never gets to the inbox though, just goes straight into the junk folder
