I dropped a large "waste" man hole cover last year after debates with the water company,it's their asset on my property but the mound leading up to it was significant. and a raised eye sore.
Having taken a course of bricks out and replaced the massive cover with a modern air tight job I got the area almost level to the rest of the lawn. - At my cost and with their permission (as if they had an argument...)
The problem I have is there is a large circular concrete "biscuit" around the the cover which only left me about 50mm to stay flat to the lawn , I put down some turf on a thin layer of soil but the expected happened in dry conditions.
Where I dropped the rest has taken and ignoring the scalps will be ok and level in time. Ignore the drain cover mosaic...
Asking in case of any natural solutions, but is astro turf the only realistic solution for covering the biscuit?
