Quick question for the drainage experts.
I had to unblock our drains today. I think the neighbours are flushing wet wipes but they deny it.
When I got everything moving and clear, I noticed that the benching in one of our manholes was cracked and holed. What mortar mix should I use for patching it up and should I add any waterproofer?
TIA
