Sewer lines need to be checked on a regular basis to prevent pipes from getting blocked or clogged. This is especially important if you live in an older home that was built before the 1980s. This is because your pipes could be made of vitreous clay, which are more prone to bends, cracks, holes and breaks. Not only will this damage let foreign objects, like leaves, dirt and other debris, get inside and clog your pipes, but it will also endanger its structural integrity. If blocked drains are left untreated, your pipeline could collapse over time, which will require a costly replacement of your entire piping system.
Another common cause of clogged drains is root intrusion. This is what happens when small cracks in the pipes underneath your home lets tree roots grow inside them. As a result, this intrusion of roots could block the flow of water, causing backup problems in your sinks and toilets.
Tell-tale Signs of Blocked Drains
To get rid of roots in your pipeline, it is best to call certified plumbers to solve the problem.
Solving the Problem of Root Intrusion
If you would like to get rid of roots inside your sewer system forever, you should opt for pipe relining. This no-dig technology is the fastest and least costly way of repairing pipes, patching cracks and holes whilst strengthening their integrity with little to no disruption. For this reason, pipe relining is a practical and affordable solution.
Sewer relining can be done on pipes that are as small as 40mm to 600mm pipes, depending on the accessibility and logistics of the piping system. Patch liners are installed in smaller pipes.
This is how the pipe relining process is carried out:
A small CCTV camera will be used to inspect the pipe. This step will help plumbers ascertain whether or not pipe relining is the best method to use. The affected pipe will then be thoroughly cleaned using a hydro-jet machine to get rid of roots and other foreign objects inside the sewer line. This process will also ensure that the lining material and host pipe will bond properly.
II. Lining Installation and Curing
Once the affected pipe is free from any debris, the lining material made of polymer resin will then be injected into the sewer. An inverter is used to coat the damaged pipe’s interior walls with a thermosetting resin mixture. Then, the process of inversion will commence, wherein air pressure will be applied to bond the lining material and the pipe. To ensure reinforcement the new pipe formed by the resin lining, hot air or steam will be applied. The liner will then be left to cure for two to three hours. For bigger pipes, hot water will be used to cure the lining material in place.
The liner will need to be re-assessed to determine its quality and the success of the relining work. This will be done by using a CCTV drain camera.
