Inset cover

[pavingpipe]

Can anyone recommend a good supplier (who is in London area or can deliver) for an inset cover approx measurements 85 x 75
also, what depth of tray would I need, as I have 60mm blocks laid so I assume you lay sand in the tray - but to what depth etc?

Go to any decent builders merchant and they should have what you're after. Your dimensions are unusual so you may need to get a 10mm steel plate and that you can cut a hole into. Put the steel over the chamber and this will reduce it's dimensions down so a standard cover will fit it. With regards delivery it's too small for anyone to bother with so best to pick it up.

My usual supplier of recess trays has gone bust, I found out last week when I visited them, because I prefer the type that take a standard key rather than have handles built in, the search started. WREKIN proved the most helpful manufacturer, who pointed me in direction of amongst others Sydenham’s builders’ merchant who proved the cheapest supplier. This was all for a 650mm x450mm opening with nominal 80mm depth which would take 60mm blocks with some sand.

Re the inset cover

what measurement do I need to take on the existing manhole cover to calculate size of tray required..?

Trays only come in standard 600x450 most common,600x600 industrial concrete rings,450x450 domestic access chamber

i always lay my blocks on a damp sand and cement inside the man holes , if you just use sand then 0ver time it get sodden with water and either the blocks move or always looks wet

i like to do the cuts around the tray (full of sand),then wack the main area, once the area around the cover has been wacked

i then do the screed and cuts inside the cover,

if you set it all up at once the blocks in the cover don't wack down like the blocks around the cover,and it ends up proud ,which looks pants

not if you have aloud for the blocks to compact around the man hole already in the screed , but i must admit ive done it your way a few times as well
funny how every 1 does things differnt hey

well you know yourself if you drive around ,the thing that catches my eye more than anything is a beautiful drive with the insert cover sticking up 5-10 mm
the sand in the cover cannot go anywhere,whereas the sand on the subbase eventually can sink a little
I know it shouldn't but this is the real world I am talking about

Just as a follow on from the thread....I have the iron manhole cover and frame ......would they be worth anything for scrap?

They weigh a lot and are quite large and take two people to lift

[msh paving]

heavy iron is making 60/70 ton in east anglia at mo, makes that lid worth a quid or so MSH

It'd be a shame to scrap it!

[lutonlagerlout]

for years i had this crazy idea of shot blasting an unusual manhole cover, welding 4 legs on it, and getting it painted ,then using it as an occasional table,the hand holes would be ash trays
funny what dopey ideas people have
