im laying some block paving for a friend. he has laid new drains ( concreted them in ) and the gullies lie only 75mm above the concrete and MOT level. given the screed of 50mm and the blocs of 50-60mm the Finished paving level will lie above the edge of the gully. any ideas how i can get them flush without digging up the gullies and grids?

how wide is the concrete around the gullies and how deep? can you scrape about 20ml off that will give you 35millish of screed? maybe undercut the pavior.

Gully 75mm above MOT / Concrete level is no problem
If using 50mm blocks, this gives a bedding sand depth of 25mm - perfectly sufficent and acceptable.
Even a 60mm pavoir gives you a 15mm bed which is adequate.
Just need to be a little bit careful when compacting the blocks where the drains are. the 'wacker plate' will bounce a little bit where the concrete is but dont over do it and you will be fine
