Hi All,
I am planning to fill my front yard with soil at the same level as retaining wall. The top level of retaining wall is approximately 300mm higher than sewer inspection point. I don't want bury the point and don't want to touch it any manner. Wondering is there any way I can create a cover with lid to protect the inspection point not be buried under soil?
Radius of The inspection point is 250mm.
Best,
Mos
