sewage manhole replacement

[notmrscookie]

My concrete sewage manhole is broken in one corner? .I knew I have to measure it but can I get a metal replacement lid or do I need a concrete one ?

it's on my grass and holes a plant pot and no cars or anything go over it ?

Thanks

The metal ones have like a rim round the inside of the bit in the ground they sit in.
Best to take a few photos including the edges when the lid is lifted and go to your local builders merchant and see if they sell the same ones or if they can tell you where to get one. Generally you buy the complete manhole but just get rid of the bit you don’t need
