im hoping to lay my edge restraints and kerbs tommorrow so just after a bit of advice!
the course against the house - do i lay this on a bed of concrete?
the course at the entrance to the drive - do i lay this on a bed of concrete?

Laying the edge course along the house wall on concrete, makes screeding a hell of a lot easier

i dont know anyone that would bed blocks tight to a wall on concrete unless it was a footpath,there is no need if the sub base and bedding layer are correct
the wall provides the restraint

Perhaps I’ve misunderstood the question LLL, but if I’m building a driveway, I bed the edging along any house walls on concrete, if only to give me something to screed off.
A method promoted on this site.
or maybe the suns fried my brain.

of course if you are using the notched board method Jim,
but I have found that any blocks laid on concrete, eventually ,even with only a couple of mm of settlement will stand proud,i.e. the ones around manholes etc
personally I would rather concrete edgings or kerbs around any free edges and keep all the blocks on the same bedding layer /type 1 layer
I used to screed freehand but have used the conduit lately and they are cheap and very useful==> worth a try
all the best

I've been in this game quite a while now, but always open to different or new ways of doing things, especially if it saves time and money

i was dubious about the conduit jim,but it worked well for me,i have used notched boards extensively and screeded freestyle ,but the conduit is more accurate i reckon

i only ever bed my edgings on concrete if there is no restraint then i haunch them as well , as for screeding ive always used electrical conduit think they are 20mm steel, they are perfect for the job , ive also got a probst screeding bar thingy that is a god send if you do it every day

i used 20mm steel conduit (im an electrician so luckily had some in the garage!) it is relatively easy!
