Hi I'm going to lay a patio I layed 26, 3x2 council slabs last year on the other side of garden, turned out not bad, but buying my slabs for this one probably 2x2 by 35mm, and a concrete slab hard wearing, but not picked them yet, so bit nervous how this will turn out.
I'm laying it on the surface below it will be 360cm x 360cm, it is ok length wise, but a little shy on the width so I'll have to widen it slightly, as the concrete surface is kind of uneven I'll put sand down to level off the concrete appropriately.
So here's the part I'm nervous about I've read you need a fall or slope of 10 mm for ever 1 metre, to 1.5 metres, so I'm going to create a slope or fall on the concrete, and the part I'm widening I will use type 1, for the base and I'll incorporate the slope in that, the part I can't get my head around is does my fall start with my very first slab, meaning higher at top lower bottom, eg touching bubble on spirit level, or bubble just slightly off if that's even possible lol, or do I start with my very first slab totally level, and slope it gradually.
Lastly as you see from the pic will I run the slope from the top to the bottom, or left to right running into the fence as you see the pic face on, hope you understand why I'm a little nervous, just don't want it sloping down too much and look stupid or dangerous, or is a touching bubble on the spirit level barely noticeable, done those slabs last year, but you can tell I'm a total novice, lastly they'll be layed on a full mortar bed, or screed if mortar is wrong term, apologies for making this thread long.
