What drain lining is
Cured-in-place pipe (CIPP) lining is a no-dig drainage repair: a resin-saturated felt liner is inverted or pulled into the damaged pipe, inflated, then cured in place to form a new structural pipe inside the old one. The result is a seamless, jointless, root-proof internal pipe with a design life of 40+ years — installed in a single day with no excavation.
