Pipe Lining vs Pipe Bursting

A resin-soaked liner is pulled into the old pipe and cured in place, forming a new pipe inside the old one.

A bursting head is pulled through the old pipe, breaking it outward while new pipe is pulled in behind.

Cracks and root entry in a pipe that still holds its shape.

A pipe that is badly broken or that you want to upsize.

A camera inspection decides which method is possible.

Collapsed sections, heavy sags or tight bends can rule out one or both methods.

Trenchless work often saves landscaping and sidewalks, but it is not always cheaper.

Lining usually needs access at one or both ends of the pipe, often through a cleanout. Bursting needs a pit at each end to pull the new pipe through. Neither needs a trench along the whole line.

Both methods replace or rehabilitate sewer pipe, which may need a permit. In Harrisburg, pipe work is handled through the City of Harrisburg Bureau of Codes and done by a city-licensed master plumber.

Bursting pushes the old pipe outward, which can affect nearby utilities if they are very close. Calling PA One Call (811) before work marks them.

Ask how many lining or bursting jobs they have done, what warranty they provide and whether they will show the final camera footage. Check their license and HIC registration with the Pennsylvania Attorney General contractor search.

Liners use epoxy or other resins cured inside the old pipe. Bursting typically pulls in high-density polyethylene pipe. Both have long service lives when installed correctly. Ask which materials the contractor uses and why.

Both methods are less disruptive than open trenching. Lining may need only a cleanout for access. Bursting needs two pits. Ask how large the pits will be and where they will go.

Lines with several bends, branches or changes in size can be harder to line or burst. A camera inspection shows the layout and helps the contractor decide.

If the pipe has a deep sag, a collapsed section or connections that need to be rebuilt, traditional excavation may be the best option. A good contractor will say so.

Make sure quotes cover the same length of pipe, access, restoration and warranty. A lower price that leaves out restoration may cost more in the end.

Ask whether the pipe is round enough to line, whether bursting is possible given nearby utilities, how long each method takes, what restoration is included and what warranty each carries. Compare answers side by side.

A camera inspection video is the common starting point for both conversations.

Many older laterals here are clay or cast iron with joints every few feet. Lining seals those joints; bursting replaces them with continuous pipe. Both can work well when the pipe's condition fits.

Many residential lining jobs are completed in a day, including curing time. Bursting jobs also often take a day or two, depending on pit locations and soil. Traditional digging can take longer, especially with sidewalks or driveways to restore.

Either way, the new or lined pipe connects to the same main and the same building drain. Your fixtures and indoor plumbing are not affected.

Keep the before and after videos and the warranty. They are valuable if you sell the house.

Older cities with narrow lots, mature trees and sidewalks close to the street are good candidates for trenchless methods, because digging is so disruptive. In Harrisburg, rowhome blocks with laterals under the sidewalk often benefit. A camera inspection decides whether your pipe qualifies.

Lining fits a sound pipe with cracks and open joints. Bursting fits a badly damaged pipe or one you want to upsize. Digging remains the answer for sags and collapses.

Trenchless methods have made sewer repair less disruptive for many homeowners. The right choice depends on your pipe, and the camera footage is where that decision starts.

A local provider can inspect your line and explain which method, if any, fits.

Homeowners ask whether lining shrinks the pipe, whether bursting is noisy and whether either method works under a driveway. Lining reduces the inside diameter slightly but leaves a smoother surface that often flows as well. Bursting involves machinery at the pits but little at the surface between them. Both are commonly used to avoid digging up driveways and walks.

The right method depends on the pipe's condition. If a drain is backing up now, call (717) 459-0752 to reach a local Harrisburg provider.
