The sewer line leakage or repair is a nightmare for the huge cost. Now trenchless sewer repair is a viable option to reduce cost and save the landscaped garden. The trenchless sewer repair is a good option if the sewer line crisscrosses your driveway and your landscaped garden. There are two methods to do this, one is pipe lining and the other is pipe bursting. None of the process is cheap, it is far cheaper to dig out the area and do the repairs work. But, the main problem is to locate the leak. If you can locate the leak it is easy to dugout the faulty pipe and replaces it. The problem is elsewhere, the main problem is there are multiple leak and the service provider has to search it out you have to bear the labor cost of digging which will be a substantial amount.
The Digging up
You have to restore your landscaped garden, survive the trauma of the trampled plants and the up-rooted driveway. The cost of suffering is not billed. However, you can survive the entire episode if you go for the alternative. But remember, your sewer lines must be free from multiple joints especially where the line is breached. If it is within your service then you can very well do it. Contact a service provider from your area, it is preferable if you need permission from the authority you must have someone whom the local authority trusts. Ask for his advice.
Finding the Breach
The trenchless sewer repair service provider will first try to locate the breach. The company can deploy a camera to get the exact location and the state of the pipe. The camera probing will cost you, but it will at least give you an idea what has happened and how the work is to be done. The service provider will give you proper guidance. Now, if the breach is in the main sewerage maintained by the local authorities, it is their cost and your headache. That is why a licensed plumber is needed. The pipe lining is theoretically an easy job. The plumber will take a flexible pipe, rather a tube fully coated with resin and inserts it in the damaged area and blow it.
The Blowing Job
The pipe lining is a mind-blowing job. The flexible pipe when blown will take the shape of the damaged pipe and the epoxy at the outside wall will harden to breach the gap. The sewerage pipe will lose the inner dimension but, normally sewer pipes have adequate clearance. The pipe lined at the time of construction normally keeps the diameter of the pipe more than sufficient so it will not hamper the flow.
The Bursting Job
There is another method known as pipe bursting. In this method a pipe is drawn through the damaged pipe and fracturing the damaged pipe simultaneously. The old pipe is thus replaced by the new one. For pipe bursting, you need two access points, the point from where the pipe will start and the end point where the pipe will end. But, fir pipe lining only one access point is needed. The difference between the two methods is only this. Now, your next question will be about the cost. It depends on the material cost and how deep your sewer line is. There are place where the pipe lining is cheap. But, there are areas where the pricing is other way round.
Back to Digging
In spite of all these arguments, the trenchless sewer repair may not be possible in your case. There are areas where pipe bursting is not allowed by the authority and your probable solution is pipe bursting and that is barred by legislation. Therefore, you have no choice. In pipe lining the flexible pipe you are using resides in the old pipe and after a few hours when the resin hardens the flexible pipe is encased within the old pipe and seal the breach, if a major part or section is missing then there is no choice but to go the conventional way.
