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?

His suggestion of using trays is probably the best option, there is,
however, quite a lot of work in dropping the level of the manhole to take
the inset tray.
He'll need 2 or 3 inches of compacted grit in the bottom of each before
adding any MOT, to allow free drainage.

Also, you may not be able to find them at a later date unless you draw out a
plan now of where they lie in relation to each other and also the house,
boundaries etc - and put it somewhere safe!

If you have a rough idea of location, you can find them easily enough
with a cheapo metal detector - assuming they are metal of course.

If you've lost a drain cover. a cheap DIY pipe/cable/stud finder, taped
to the end of a stick, works well. I used mine to find one of my
neighbour's, which was buried among a load of brambles and nettles.

I buried one under gravel once, by lowering it a bit. It did not get
exposed again. (I was unlikely to want to get to it ever again anyway,
since it was access to a large surface water drain pipe (1m diameter)
that run under mine and several adjacent front gardens). Every property
seemed to have a manhole access to it, even though it was nowhere near
where any pipes connected to it. I just lowered the original cover.

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.

Andrew,

Others have suggested ways of resolving your problem, but you haven't said
if you intend to drive a vehicle over the driveway once its been
'gravelled'.

If it's your intention to drive a car etc up that drive, then be aware that
you will need something a bit stronger than the usual standard light-duty
manhole cover to take the weight - especially if its to be 'buried' under
the gravel.

Yes, both covers will potentially have to bear vehicle weight. The
builder is aware of that - pointed out that one of the existing covers
is a bit lightweight (has stood up to an MPV for the last 8 years
though).

I kept losing my outside stopcock, so banged in an earthing rod and
painted the top yellow.
