Sooner or later home drain pipes fail. The reasons can be varied; tree root impingement, improper initial installation and pipe getting crushed by a heavy object passing over it are the most common reasons for failure. When these pipes fail homeowners better be aware of pipelining or they could end up with a high repair bill. Pipelining companies ensure that their process saves time and money by managing to bypass the need for the messy and expensive digging of a trench for the replacement pipe.
What Is Pipelining?
Pipelining is a trenchless pipe repair technology; there are other technologies which also do not require the digging of trenches for pipe repairs and replacement, pipelining is just one of them. Pipelining is a technology where a pipe lining material is inserted into a pipe and attached with resins to the pipe’s interior walls.
How Is It Done?
The procedure for installing pipe liners to repair damaged or holed drain pipes is as follows:
First the pipe interior surfaces are inspected using miniature cameras mounted on long cables. If the pipe is not too badly damaged, the pipelining process can be used to repair it; otherwise the heavily damaged pipe section will require replacement.
Then, the pipe internal surfaces are cleaned, usually through high pressure waterjet.
Next the pipe is measured and the appropriate length of pipe lining material is cut.
Binding resin is mixed and poured into the pipe liner. The pipe liner is loaded to the inversion machine which inserts and inverts the liner inside the pipe. Air pressure is introduced to expand the liner and make the resin side stick to the pipe’s internal walls.
The liner is allowed to cure and then the air pressure is released.
What Are The Advantages Of Pipe Repair Through Pipelining?
One of the biggest advantages is lower cost. Since you don’t have to dig a trench to repair the pipe you save on labor and equipment rental costs. More than that, you save a lot on interferences. Trenches may cut across floors and lawns requiring costly restoration work; but since pipelining does not involve digging trenches, there are no floors or lawns to restore.
Pipelining prevents future problems at drain pipe joints; the liner seals these joints so you need not worry about leaks there anymore.
Pipelining strengthens the pipe. The liner and resin fills small cavities and pinholes on the internal surfaces of drain pipes. Once cured in place, the liner acts like an extra layer of pipe.
Pipelining prolongs the service life of drain pipes providing cost savings in the long term. The pipe lining material does not corrode so it lasts longer than metal pipes. Cured pipe lining is also smooth so flow through the drains improve
Drain pipe repair using cured in place liners is faster than pipe replacement. In addition the process does not create lot of mess to clean up after.
If your drain pipes need repair, pipelining technology may be worth considering. You can find contractors providing trenchless technology repairs through the Trenchless Technology Directory.
