We're having our driveway gravelled (standard hardcore + 15-20mm
gravel method). There are two drain covers, standard rectangular
shape/size. Our builder isn't sure how to handle this. They could be
left to stand proud of/level with the surface of the gravel, but I
suspect they would look better covered. If the latter, what is the
best approach? If we just use the same or similar covers but lowered,
the gravel will probably move off their flat, smooth surface too
easily. He suggested a screed tray with some sort of material in it
to provide grip for the gravel above. Does this sounds reasonable?
Is there any 'best practice' for this? Any experiences to share?

If the levels work out, how about gluing[1] some of the gravel (well
washed) to the top of your existing metal covers. I'm not suggesting
this as the final finished layer as I don't think it would stand up to
traffic abuse but just as a key to stop a further thin layer of gravel
from sliding off.

[1} I'm thinking of one of the outdoor rated sticks like variants,
perhaps one of the Siroflex MS products, generously applied.
