Methods of Trenchless Sewer Repair

sewer-line-repairSewer repair used to be a complex and expensive proposition. Sewer lines are usually buried beneath the ground, which can afford them more protection than other types of piping in your home, but involves a number of serious drawbacks as well. There isn’t anything inherently different about problems with a sewer line – usually involving a leak or a clog just like any other pipe – but reaching it could be a serious problem.

Sewer repair used to mean excavating the entire line, fixing the problem, and burying it again. That meant renting expensive construction equipment and extra men hired to work. The excavation process could take days, especially if bad weather rolled in, and when it was done, the homeowner’s yard was left in a terrible state (requiring further costs for landscapers to repair the damage.)

All of that arrived before the advent of trenchless technology, however. Now, the same repairs can be conducted without having to excavate the pipe, which means they take much less time and require much less equipment to handle properly. What kinds of equipment does trenchless technology employ? We’ve provided a quick breakdown of some of the more common tools used to perform the operation.


If you have a cell phone – and who doesn’t these days? – it probably has a video camera and a light about the size of your fingernail. It lets you take pictures and even video from anywhere just by pointing and clicking. The same technology can be used to get a detailed look at the problem with your sewer line. The pipe technician runs a Pushcam line down into the pipe, pinpointing the exact cause and location of the problem. With that information in hand, proper repairs can be planned, all without having to do a single bit of digging!


In many cases, the issue with the sewer line is a simple leak, which needs to be plugged up. Slip-lining provides an elegant way of doing that without having to dig up the pipe. The liner is slid in through the pipe and inflated, pressing up against the sides. The adhesive on the outside of the lining causes it to bond with the pipe itself, forming a tight and effective seal. Once the adhesive sets, the leak is repaired and the pipe can be safely used. Slip-lining is especially effective for pipes with multiple leaks, allowing all of them to be sealed in one fell swoop.


When it comes to clogs in your sewer line, hydro-jetting makes an excellent way to get rid of them with no digging involved at all. It’s a powerful hose, fitting onto the line, which sends a series of short bursts of water through the pipe. The results scour the pipe clean of any detritus or debris. It requires a professional to use, since water can be dangerous when released at such pressure. But it’s remarkably effective and since it involves only water, it damages neither the pipes themselves nor the environment as a whole.
