What to Know About Trenchless Sewer Repair

by Carter Toni

Plumbing issues are quite common in many households. Proper maintenance should be done to avoid any further damage which has greater consequences. A trench means a narrow ditch or hole that is dug into the ground for repairing piping and other plumbing-related issues. Trenchless sewer repair as the name suggests doesn’t require digging a hole to conduct an inspection of the pipes. Trenchless sewer repair gets a lot of work done without diverting the water flow.

Traditional sewer methods are invasive, require heavy-duty excavation equipment, create a huge pile of dust and dirt, causing inconvenience until work is done, and add the cost to put everything back together again. All these things take lots of time to complete. Trenchless sewer repair on the other hand takes very little time to detect the problems and can be easily solved without any damage to the piping system.

There are four types of trenchless sewer repair:

1) Structural pipeline: The professionals use an epoxy-based liner that swells inside the pipe, it is left to cure for a few hours, and when removed the pipe is good as new.

2) Spray lining and brush coating: This technique is similar to the structural pipeline, instead of using a liner to create a new pipe inside. The epoxy or flexible polymer is sprayed or brushed into the pipe creating a new layer that fixes the pipe.

3) Pipe bursting: It is used to replace the damaged pipe by using a winch with an attached bursting head to pull a new pipe into the old pipe. The old pipe breaks in the process and a new one takes its place.

4) Slip lining: This is an old trenchless technique in which a smaller diameter pipe is fitted into the existing pipe and the extra space is filled with cement or plaster.

The process of Trenchless Sewer line:

1) Inspection: The professionals perform the initial inspection with a small camera that is connected to a video monitor. With the camera, they can see easily if the pipe is clogged, crushed, broken or damaged by tree roots, or otherwise obstructed.

2) Cleaning: After the analysis, the inside surface of the pipes is cleaned so that the liner can be applied and adheres properly. If the pipe is blocked by roots then a rotating blade is inserted inside the pipe to cut the roots extended inside.

3) Pipe Lining: After the cleaning process is done it’s time for pipelining. If the damage is not huge, a sewer pipe can be relined. The liner is similar to a deflated fire hose. It is coated to the internal surface with a special epoxy. Then a long tube called a bladder is inflated inside the liner pressing it tightly against the inside of the pipes. After the new liner is cured, dried, and hardened the bladder is removed and the sewer pipe is ready to use with a smooth intact surface.

4) Quality check: A final inspection is done to ensure the standards and quality is maintained. The liner should stick perfectly with epoxy to ensure it stays intact. Once assured, the line is connected and the pipes are good to go for a minimum of 40-50 years of service life.

Benefits of Trenchless Sewer Repair:

1) Time and cost efficiency: Trenchless Sewer Line and repair saves a lot of time and money. It is minimally invasive only to insert the camera and liner. The traditional invasive technique requires the destruction of floors, walls and rebuilding the space which adds extra cost. Plumbing problems are repaired faster, usually in a whole working day or even lesser than that depending on the nature of the damage.

2) Environment friendly: The process is quick and easy and can be done without causing damage to the ecology. The landscape and other infrastructure stay intact. There is no wastage of the debris that occurs in the traditional invasive process.

3) No side effects: The process does not involve excavation. Therefore, there are lesser chances of infiltrating or contaminating the water supply of the house as well as the neighborhood. The plumbing system will last longer and requires less maintenance once installed.

Final Words:

The easiest and best way to repair the plumbing system is the trenchless sewer line and repair. Intelligent Design professionals have all the proper tools, devices, and equipment required to do the job in very little time. They also offer a guarantee of 50 years after the installation.
