Anyone know of a plastic sleeve product which will go inside an old clay
soil pipe? As far as I can tell the old pipe has about a 4" internal
diameter.

Details: I have come across an old soil pipe which is very badly
cracked - at least to the parts that I can see - and has small roots
growing in to it through the cracks. The ideal thing would be to replace
it with a new one but parts of the existing pipe are fairly inaccessible
without going to a lot of extra cost and would require damage to an
internal tiled floor that I may not be able to match with replacement
tiles.

So I wondered if it was possible to buy a plastic internal sleeve for
such old pipes. The idea is that the sleeve would support the walls of
the existing pipe, stop water leaking through the cracks, and provide a
good end to join on to the subsequent pipe.

That's the idea. Is there any product for a problem such as this? Unless
it is flexible I would only need a short length - say less than 2 feet.

Weren't water companies running some sort of pig down their old ceramic
pipes and lining them with plastic to save the cost of relaying them ?
The ceramic providing the structural strength, and the plastic sealing
any leaks ?

Suggests there's a commercial sector out there ....

I think they do that for the big (12 inches and upwards) cast iron stuff.

Oddly enough I have roots getting into a 4 inch ceramic soil pipe too. I
will be digging it up in the next couple of weeks and may also be trying
to "line" one section (under a large shrub / small tree).

Yes, Working for a school I saw the preparations for sleveing an old
drain. It involved putting a glass fibre liner in the drain and then
treating the liner with resin.

Unfortunately I did not see this done as it was decided that it was mor
cost effective to continue cutting the roots (which were the original
problem) than sleving the drain.

I woulds suspect that asking for quotes around the larger compaies
(probably not Dyno Rod) might produce some prices/info

A professional company can line the inside with an epoxy soaked sleeve
(inverse bandage) - this is held in place by a balloon until set. It is
a standard drain repair method where direct access is undesirable.
