Trenchless
Trenchless sewer repair in Indianapolis: lining and pipe bursting
The reason Meridian-Kessler and Broad Ripple still have their trees is that nobody has to trench through the roots anymore. Lining rebuilds the pipe from the inside; bursting replaces it from the inside. Both need one or two small pits, and both start with a camera to make sure the old pipe can take it.
Two methods, two different jobs
Cured-in-place pipe lining (CIPP). We clean the old pipe with the jetter, then pull or invert a felt liner soaked in epoxy resin through it from the cleanout, inflate it against the pipe wall, and cure it with hot water, steam or UV light. When it hardens you have a new, jointless pipe inside the old one, about a quarter inch thinner in diameter. Roots have no joint to enter. Trenchless pipe lining Indianapolis-wide is what we use on clay that is cracked, root-damaged or slightly offset but still round, which describes most of the laterals north of 38th Street.
Pipe bursting. We dig a pit at the house and one at the main, thread a steel cable through the old pipe, and pull a conical bursting head followed by a new HDPE pipe. The head splits the old clay or cast iron outward into the soil and the new pipe takes its place at the same diameter or one size up. Pipe bursting Indianapolis contractors use where the old pipe is too far gone to line — a collapsed section, a badly crushed run — but the route itself is still usable.
Which one your pipe needs
| Camera finding | Lining | Bursting | Open trench |
|---|---|---|---|
| Cracked or root-damaged clay, still round | Yes | Yes | Not needed |
| Minor offset joints (under 20% of diameter) | Yes | Yes | Not needed |
| Severe offset or partial collapse | No | Usually | Yes |
| Full collapse, camera can't pass | No | Sometimes, after a spot dig | Yes |
| Belly or reverse slope | No | No | Yes |
| Orangeburg, deformed | No | Sometimes | Yes |
| Under a mature tree, patio, or the street | Best | Good | Expensive |
The honest summary: lining fixes the pipe wall, bursting replaces the pipe, and neither fixes the grade. If the camera shows standing water in a sag, that stretch has to be dug. We do a lot of hybrid jobs — dig and re-lay the belly, line the rest.
Why it matters under our trees
The tree lawns and front yards in Meridian-Kessler, Butler-Tarkington and Broad Ripple carry pin oaks, silver maples and sycamores that went in when the houses did. An open trench from the house to the main cuts through most of the root plate on a 70-year-old oak, and the tree is often dead within five years. A lining job needs a pit at the cleanout — or no pit at all if there is a basement access — and the tree never knows we were there. That is the main reason trenchless became the default here, and how lining handles roots and bends goes into the mechanics.
What it costs
Trenchless sewer repair in Indianapolis runs $6,000–$20,000. Lining is priced per foot plus setup; a 50-foot lateral is typically $6,000–$10,000, a 90-foot run to the far side of the street $10,000–$15,000. Bursting is a little more because of the two pits and the pavement cut at the main. Reinstating branch connections (a basement floor drain tee, for example) after lining is a line item each. The cost page has the table. Compared with an open trench that crosses a driveway and a sidewalk, trenchless is usually the cheaper total once concrete restoration is counted.
What it doesn't do
A liner is a permanent fix for the pipe wall, and manufacturers rate them at 50 years. It does not fix the connection at the main if that is broken, it does not add a cleanout, and it cannot be installed in a pipe we can't jet clean first — a pipe full of scale or a partial collapse has to be dealt with before the liner goes in. We tell you all of that from the camera footage, not after the liner is on the truck.
Permits
Lining and bursting are lateral work, so the Citizens Energy Group bond and permit rule from 1 January 2026 applies the same as a dig. The connection at the main is inspected either way. If a contractor tells you trenchless doesn't need a permit because there is no trench, that is wrong.
The rest of the work
Before lining: hydro jetting to strip roots and scale. Instead of lining: a spot repair when there is one bad spot, or a full replacement when the grade is wrong. Every one of them starts with a camera inspection.
Other sewer services
Sewer Line Repair
A camera-located spot repair of the one or two bad sections — a collapsed clay joint, a root ball, a crushed Orangeburg run — instead of replacing a pipe that is mostly fine.
Sewer Line Repair →Sewer Line Replacement
A new PVC lateral from the foundation wall to the Citizens main when the clay or Orangeburg is failing along its whole length. Open trench, permit, inspection, restoration.
Sewer Line Replacement →Sewer Camera Inspection
A recorded video scope from the cleanout to the Citizens main, with every crack, root and offset located and its depth marked on the lawn. $250–$500, credited to the repair.
Sewer Camera Inspection →Hydro Jetting & Drain Cleaning
High-pressure water that strips roots, grease and cast iron scale from the pipe wall — the right tool when the line is sound but choked, and the prep step before lining.
Hydro Jetting & Drain Cleaning →Questions we get asked
How long does trenchless lining last?
Liner manufacturers rate cured-in-place pipe at 50 years, and the oldest residential liners in the country are now past 30 with no failures from the liner itself. The weak points are the ends and any reinstated branch, which is why we scope the finished job and give you the video.
Can you line a pipe with roots in it?
After jetting, yes. The roots are cut out and flushed, the camera confirms the pipe is round and clear, and the liner seals the joints the roots came through. Roots that broke the pipe apart rather than just growing into a joint usually mean bursting instead.
Does the liner reduce the pipe size?
By about a quarter inch on a 4-inch or 6-inch lateral. Because the new surface is smooth and jointless, flow is usually better than the old rough clay, not worse. Lining a 4-inch line is normal; we would not line a 3-inch one.
Can you go trenchless under the street?
Yes, and that is where it saves the most. A pavement cut in a city street needs a separate right-of-way permit, traffic control and full-depth restoration, which is often $3,000–$6,000 on its own. Lining from the house to the main avoids all of it; bursting still needs a small pit at the tap.
