We have this cover on a path on our allotments
It is rather old and we want to see how deep is , but cant seem to get it off
Tried crowbar, but no joy....
Its cast iron with concrete inserts, built on a brick base and is over 50 years old i reckon
Edit:
have sent pic of to san gobain pipelines who reckon it was made 1940/50's and could weigh around 60/70 kg, with a concrete infill
They stated it would need a complete new unit to take surface water.
Do you think it would be possible to knock out the concrete infill?
