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
