What 'no-dig' actually means
Trenchless drain repair is a family of techniques that fix damaged underground pipes from the inside, without excavating to expose the pipe. This includes patch lining, full-length cured-in-place pipe (CIPP) lining, mechanical re-rounding, and pipe-bursting for full replacement without excavation. Around 70% of structural drain defects in UK domestic drainage are repairable using no-dig methods.
