FAQs about Pipe Relining and Their Answers

Among the many trenchless solutions applied for pipe restoration; it seems pipe relining is the most widely used in many countries. Despite its popularity, many people are still not familiar with how pipe relining is done or some basic information about it. Here are the top FAQS about pipe relining and their definite answers.

The basics of pipe relining

In pipe relining, a resin liner (usually made of epoxy) is placed inside the sewer pipes and becomes the new main pathway of the sewage wastes. The resin liner closes gaps or cracks in the pipeline and drastically improves the condition of the sewer system.  

How does a pipe relining operation happen?

1. The first thing that happens when conducting a pipe relining procedure is the cleansing of the pipeline and removal of obstructions. This process will ensure the resin liner goes through the pipeline smoothly and no issues. A water jet is commonly used to clean and take out blockage in the sewer pipes. Sometimes a pipeline is too damaged that it must be excavated.  
2. After the pipes are removed, the resin liner is placed on a bladder and then integrated into the sewer pipeline. The resin liner doesn’t have a true solid form yet which is why it’s bonded on the bladder. The bladder will safely guide the resin liner through the pathway of the pipes.
3. Once the bladder has reached the optimal position, it’s expanded so that the resin liner can stick on the pipe lining.
4. Hot water or steam is applied to the resin liner so that it will harden faster.
5. A few final tests are conducted to see if everything is fine with the installation of the resin liner.

How long does pipe relining take to be finished

This will actually depend on the degree of the pipes that need to be repaired. Of course, if various pipe sections need to be repaired then the project will definitely take a long time to be finished. But generally, a standard pipe section relining won’t take more than 10 hours to be completed. Curing time and temperature are also factors for how long the project will take.

Is the resin liner reliable?

Some people are often sceptical with the usage of resin liner since it’s not really a pipe. However, little do they know that resin liner is far more reliable and better than most mainstream pipe materials in modern sewer lining. A high quality resin liner can be four times stronger than PVC — a popular pipe material used in most sewer pipes today. Resin liners aren’t just durable, they’re also be to withstand constant chemical exposure and acids. You also won’t have to worry about root intrusions since resin liners are virtually immune to root attacks and even leakage.

What are the benefits of applying pipe relining?

*Pipe relining provides the least destruction to the surrounding property of its work site

*One of the fastest pipe repair methods available in modern sewer pipe restoration

*Doesn’t only repair broken pipes; it also improves the overall condition of the sewer system

*Very affordable due to the absence of heavy or major excavation methods.
