The raised concrete kerb around the external trapped gully
serving the kitchen has started to deteriorate. The concrete has
flaked off exposing the rusting reinforcement.

The house wastes now enter through a single plastic pipe into the
side of the ceramic gully, below the grating, the pipe being
concreted in, though I have no idea how it actually seals to the
gully.

I would now like to tidy things up. To reinstate as is, it looks
like I need a kerb with inside dimensions about 300 mm x 600 mm.
I have had a quick Google, but most of what I can see are for
supporting road gullies, so not much help.

The next option is to try and build up the remains to the
original outline, with mortar, but I fear that the rusting rebar
will simply shed it again pretty quickly.

The gully has an outside tap above it, and can be handy for
washing brushes without domestic disapproval. Nevertheless, I
suppose that it would be possible to get out the angle grinder
(well it had to come into it at some point) and take away all
trace of the original kerb and the internal haunching, and simply
re-finish level with the surrounding paving.

I am a little concerned that if I get too close to the gully
(1970s vintage), it may well crack, and I don't really want to
fit a new one* and start chasing pipework to find an intact
joint, not least because the manhole a couple of metres away is
at least 2 metres deep.

*BTGTTS but at least in that house we were the first on the run,
and it was fairly shallow. The gully had been cast into the
concrete patio, which I was removing. Just as well really, as,
once the damaged gully was removed, I discovered the next pipe,
also taking the soil pipe output, had clearly been cracked for
quite a while. The stirrup pump came in handy to empty the
excavation.

When I dug up our old salt glazed drains (now replaced with plastic),
they were
cracked in several places - for who knows how long.
The ground around was heavy clay, and so contained most of the
effluent.
But the clay was kind of smelly and a strange dark grey colour for
around 8 inches
round the pipe. Would have been much worse in a sandy soil I guess.
Our manhole was 2 metres deep (public sewer), but the drains went
down to about 1 metre as far as I excavated. At some point I guess
they would have plunged downward steeply - I was glad not to get that
far !
