Got a pic of the old lid etc. Was it in 2 halves and joined by a pin?
It was one piece before it broke, approx 660mm x 400mm ish.
From the picture I'm genuinely confused how it was stuck.
Wheel in with bumper resting on ground.
I didn't explain.
Buy a new cover plus surround
To replace the surround would mean digging up the concrete around the drain to cement a new surround in. Although the driveway is going to get refurbished soon anyway, but until then it needs covered with a new/old lid that fits.
Am I right in thinking that you're replacing the broken cover?
If so, why?
From what I can tell you did nothing wrong and the only reason the cover collapsed was because it was in a shocking state to begin with. If anything, I'd say those responsible for its maintenance owe you to the tune of at least £30.
Yes I want to replace the cover. It broke because it was probably 100 years old with a hairline crack in it. I always try to avoid it but it was bin day and bins were in the way.
