My septic tank has 3 manholes in the lawn, the concrete fillet round the edges is cracked & does not look nice.
To repair I was thinking of digging away grass & old concrete, then make a wooden frame to go round the metal lid leaving about 3" of space & then mixing concrete & replace the old.
Is this how it should be done?
also
Should I use sharp sand & cement or ballast.
What ration should the mix be?
Thanks
