Since being adapted for use in municipal pipes, trenchless techniques have dramatically changed the way that repairs are conducted. Now, instead of having to dig up the entire pipe to repair or replace it, one can take care of the entire thing where it is. Though exhumation is still used sometimes, trenchless repair has a lot to recommend it. There are many different kinds of trenchless pipe repair services, each of which has its own advantages and disadvantages.
One of the more common methods of trenchless pipe repair is pipe lining. This involves inserting a pipe liner all the way through the damaged section of the pipe. Once the liner is in place, it is expanded using air bladders until it is flush with the inside of the “host” pipe. The liner is then secured at both ends of the section, making it a permanent part of the pipe. Pipe lining provides an added layer of protection to the host pipe, and prevents corrosion or tree roots from opening up more leaks. Linings have an average lifespan of around 50 years, so once one is in place you don’t have to worry about it for quite a long time.
Cured in Place Pipe (CIPP)
Cured in place pipe, or CIPP, is a particularly interesting type of trenchless pipe repair method. First, an epoxy containing resin and fiberglass is mixed and inserted into an applicator tube. The tube used can be as long as the entire pipe or as short as a few feet, depending on where in the pipe the solution needs to be applied. Once the applicator is loaded, it is inserted into the pipe and gradually turned inside out by rolling it against the pipe walls. This brings the epoxy into contact with the pipe walls, where it will form to the shape of the pipe and harden. After several hours of hardening, the applicator is withdrawn, leaving a sturdy shell behind. This shell can repair minor cracks or leaks in the pipes, as well as replace entire broken sections if applied correctly.
CIPP helps to homogenize the inside of the pipe, smoothing it out and covering over any irregularities that might be affecting its efficiency. The ease of application, combined with its longevity and effectiveness, has made CIPP one of the more popular forms of trenchless pipe repair available. Which technique is used, however, depends on the professional and the state of the individual pipe. What’s important is that you call for repairs as soon as you suspect an issue with your drain or sewer system. The faster a plumber can address the problem, the more damage can be prevented and the better off your system will be.
