If you need repairs to underground sewer or water pipes for your home, you may be dreading the damage to your property. You may be imagining a torn up lawn, a ruined garden, a huge ditch, or, in the worst-case scenario, even pulling up a driveway, patio, or paved path! But your yard doesn't have to look like a disaster zone – thanks to trenchless pipe repair. Read this article to learn more.
How Does It Work?
There are two main methods of trenchless pipe repair – pipe lining and pipe bursting.
Pipe bursting is a technique that simultaneously installs a new pipe and destroys the old pipe. Small holes are dug at either end of the line that will be replaced, and a cable is run between them. A conical "bursting head" is run along the cable, breaking it apart from within, and then the new pipe is pulled into the space left behind.
Pipe lining works by coating a felt liner with two-part epoxy. As with pipe bursting, two holes are dug, and the liner is run through the length of the pipe, with an inflatable bladder within. When this is inflated, it pushes the liner out against the original pipe, where the epoxy cures and hardens. The bladder is then removed, leaving you with a new pipe within your old pipe.
Are These Pipes Really Durable?
The warranties on these pipes speak for themselves – they're just as durable as a traditional pipe. They even have some key advantages – both kinds are seamless, for instance. And while the pipe created through pipe lining will be slightly smaller than the original, this is no problem, as the epoxy used in pipe lining leaves you with a very smooth interior surface, increasing flow and resisting calcification and blockages.
Which Method Is Best?
This depends on the specifics of your plumbing problem. One of the advantages of pipe lining, for instance, is that it can be used to replace a smaller section of damaged pipe. Pipe bursting, on the other hand, works best when a large section of pipe needs to be completely replaced.
The depth of the pipes is also important. In colder areas where frost penetrates the ground, sewer and water pipes are generally buried deeper. For deep pipes, lining is more cost-effective than bursting. Pipe bursting is more common in the southern United States, where pipes are likely to be closer to the surface.
