Trenchless Sewer Line Replacement, explained.
Some sewer lines cannot be repaired in place. The pipe may have collapsed, the grade may be wrong or the material may be too deteriorated to line. In those cases the line needs to be replaced, and the question becomes how much of the property has to be dug up to do it.
Trenchless replacement answers that with methods such as pipe bursting or directional boring. Both work from small access pits instead of a continuous trench. We use a camera and a locate first to decide which method fits your line, and we tell you plainly if a short section of open excavation is still the best way to correct a sag or cross another utility.
