In time sewer drain pipes will fail due to age, tree root intrusion, corrosion, ground movement and calcification. When they do fail the homeowner is saddled with a rather large repair bill. Thankfully, new technology in the form of trenchless pipe repair cost less than conventional pipe repair and replacement methods.
With conventional pipe repair and replacement methods, the cost of pipe replacement is magnified by the collateral damaged caused on affected areas in the home. If the drain pipe passes through driveways, floors, landscaping, roadways, parking lots and porches, these must be dug up and restored. In the process of digging a trench to remove the damaged drain pipe, other systems such as electrical, gas and water supply lines may have to be removed as interferences and restored after the repair. There is a lot of mess all over the home caused by all the required digging.
Trenchless pipe repair cost today is less because it does away with most of the digging. At most you’ll only have to dig small sections at either end of the pipe to be repaired or replaced to gain access. Almost all installations using the various trenchless pipe repair technologies can be done through an average 4” size cleanout. Compared with the dozens of yards of trench digging and subsequent surface restoration required using old technology and you’ll appreciate the cost saved when using trenchless pipe repair technology. A recent Cleaner Magazine article reports on yet another company offering trenchless pipe repair.
There are several technologies used in trenchless pipe repair. The two most popular methods are pipe bursting and cured in place pipe lining; pipe bursting involves pipe replacement while cured in place pipe lining merely repairs existing pipe. If you have a broken section of drain pipe it would not be advisable to just go ahead and choose a trenchless pipe repair method. The first thing to do will be to ask a good plumber to conduct an inspection of the affected sections of drain pipe.
If your drain pipe is not heavily damaged, then the cured in place pipe lining method may still apply. Under this method, the first step is to clean the interior of the pipe. The most common method for cleaning is through the use of a high pressure waterjet. After cleaning, a PVC impregnated lining material is inserted into the pipe. Then hot air or steam is introduced to blow up the lining material so it hugs the pipe internal surfaces, and to cure the lining material so it hardens in the correct position – against the internal pipe wall. This even eliminates leaks at joints and stops pipe corrosion.
When pipes have to be replaced, pipe bursting is the preferred option. In this method a cutting head is pulled through to burst the old pipe and clear a path for the new one. New sections of pipe can then be pulled through without having to dig trenches. It is even possible to use larger heads when the new pipe is bigger than the existing one.
Because of the lower cost and faster work completion, many homeowners are choosing trenchless pipe repair methods. Perhaps you should give it a try.
