Proving that i am still a novice i have started setting out a 9sqm segment (1/4 circle) of block paving and have a problem with the 'exposed' edge. I am overlaying the blocks on an existing concrete base.The 2 sides that form the 90 degree angle (3m lengths) i have layed with soldier edges and haunched them in channels between the paving and the house walls (due to low dpc), in a corner.
The outer curved edge is a 'free edge' and this will finish as a 'step' down onto the existing concrete drive as there is no fixed object to butt up against. Therefore to restrain the paving i really need to haunch but it will look ugly.
What options could i have to restrain this outer edge.I cannot cut into the existing concrete and lay say a decorative edge and therefore something like this would still need fixing well into place.Would it be possible to say to lay the first 2 courses on a concrete bed to give extra strength and then smooth off under the outer edge of blocksto give a neat finish ? or is this just wooly thinking ! There is only light foot traffic on this area but i am conscious of Tony's insistance on locking the paving in to for the integity of the finished job.
Secondly, as i am laying only a small area onto a rigid base and intend to use the 'pre-compaction method' and as compaction is not required for the first stage can i use an alternative to a plate compactor and only hire this kit for the completion stage?I don't wish to cut corners but there may well be some time between screeding and the finishing parts as i am a little slow with my projects!
