I have just recently had my driveway block paved with Driveline 50 blocks. The contractor put in a good base of about 6 inches and sand on top which were compacted but my concern is the edging especially where it meets the front lawn to one side. The edging blocks are sitting on the bed of sand and are held in by cement from about 10mm below the top of the block and about 5 inches wide. Also the edging is curved.
Can anyone tell me if i have a problem as the appearance of the drive is very good.

are there any kerbs or edging restraining the blocks from lateral force??
haunching it (which sounds like what they have done) is not really a nice finish and is more likey to fAIL
its all down to what they quoted really
hope this helps

no kerbs or edging restraints on side where paving meets the lawn,just the haunching.
In quote it says 'one course of blocks or edging stone will be laid header course in sharp sand and cement to form solid edge'. Do you think I have any come backs?

Must admit that's the way we do it, a good hanuching of concrete - haven't had any bust out to date.
Agree - a PCC egder would be best, but would it look right?
I think aslong as the haunching is done properly, there will be no problems.

bang on dave,if it is done in concrete and a good strong mix it should be ok,as long as the paving and the grass are roughly the same level
a lot of lads just lay all the blocks on sand then run a 2 " fillet of mortar round the edges which is crap
TBH ianj if yours looks good there is no meovement it is probably ok
dont lose any sleep over it

Thanks guys, obviously a common practice then. It angles about 45 degrees into the soil and is at least double the 2" mentioned. Can sharp sand and cement be classed as concrete?. It looks solid enough,smooth and light grey in colour.
cheers

sand/cement is not really strong enough, a concrete restraint is far better

I think I have no choice but to accept the work as the use of materials were clearly quoted and hope I have no problems as I won't be driving over that border. I wish now I had done some research before the job was started and not after.
