If you’ve got a pipe or sewer line with a problem, you’ll need to dig up the entire length of the pipe and replace it, right? Not so fast. Trenchless pipe repair and trenchless sewer repair technology have come a long way just in the last decade, and you shouldn’t make a move on your repair until you learn more about this innovative process.
How CIPP Liners Actually Work
How can you repair a pipe without digging it up? The answer is something called “cured in place pipe,” commonly referred to as a CIPP liner. This technology works by inserting a seamless, jointless tube made of a resin-saturated material (polyester or fiberglass cloth are two popular choices) into the existing pipe. This can be done from a single upstream excavation point, using either water or air pressure. Hot water, steam or UV light is then used to “cure” these liners so that they fit snugly inside the existing pipe. They can therefore eliminate leaks and other concerns. CIPP liners can even last for 50 years — just as long as a brand-new pipe.
The Upsides of CIPP Technology
CIPP liners offer many advantages. Some, such as their resistance to corrosion, are associated with the materials that they’re made of. But most are associated with the convenience of not having to excavate along the entire length of the pipe or sewer line in question. That means not having to worry about disrupting any ground operations or restoring grounds and landscaping. If done right, it can also be kinder to the environment because it doesn’t disturb plants and prevents the leakage of harmful substances into the soil and groundwater.
The Cons to Consider
As with all things, there are some cons to CIPP liners. The major one is that they may cost between 30% and 50% more than simply digging up the pipe or sewer line in question and repairing or replacing it using traditional methods (of course, that cost may be offset by the advantages discussed above). And if you’re working with an unusual diameter of pipe, you may need to have a liner specifically made for your project. You’ll need to discuss those kinds of details further with a plumbing company experienced in trenchless rehabilitation methods.
