TL;DR
Trenchless pipe lining is the rehabilitation of a damaged sewer or drain line by inserting a resin-saturated felt or fiberglass tube through existing access points and curing it in place, creating a new jointless pipe inside the old one without excavating the yard. Known as CIPP, the liner cures by hot water, steam, or UV light and slightly reduces diameter while sealing cracks, root intrusions, and missing pipe sections.
What it means
Trenchless pipe lining is the rehabilitation of a damaged sewer or drain line by inserting a resin-saturated felt or fiberglass tube through existing access points and curing it in place, creating a new jointless pipe inside the old one without excavating the yard. Known as CIPP, the liner cures by hot water, steam, or UV light and slightly reduces diameter while sealing cracks, root intrusions, and missing pipe sections. It needs a structurally continuous host pipe, so collapsed or badly back-pitched lines still require dig-and-replace, and a post-cure camera run verifies that reinstated branch connections are open.
