Repair

I have a large drive, laid by certified contractor, but unfortunately in 2 areas the paving has sunk slightly... not huge, around a dozen Paviors affected in each location.

These are Blockley Clay 50mm Paviors

If I pull out affected Paviors, I will need to top up the sharp sand and then wacker plate them back in .... I have access to wacker plate.

Anybody advise what depth I should top up to .... i.e how far down from face of the correct level paviors.

Anybody able to give a guide on this ?
