Drain relining is a cost-effective and highly convenient method of repairing damaged drain pipes. But how much does it cost to reline your drains?
A drain is said to be damaged when there are cracks and other similar defects. Commonly, these cracks will cause leaks and foul smells if left unattended. But, to the worst, they may even cause structural damage and subsidence.
Drain relining is fitting a protective layer to the inside of the damaged drains, thus protecting against cracks, gaps, holes, cracks and bridges. These defects are easily found by doing a CCTV drain survey. A drain lining, also known as a professional patch, is a reinforced, leathery-like material added to drains, covering all these defects.
Fitting a drain lining requires special equipment (a pressurized rod). Since the drain lining is resistant to chemical erosion, you shouldn’t be worried that it’ll be damaged by soap or bleaches over time. There’s a wide range of drain linings that you can choose, most falling in a 75 to 450mm diameter range.
Here are some of the benefits of re-lining when compared to replacement:
Before hiring a contractor, always ensure they meet all the relevant standards set by the regulating body. If Water Industry Specifications (WIS) standards are followed, then the liner's lifespan should be around 50 years.
Additionally, the contractor should offer a good warranty and guarantee- not less than 5 years. Finally, remember that most relining projects are supposed to be completed in a day.
Since drain relining is not suitable for all drain problems, jet washing the internal surface of the drain followed by an inspection by a CCTV camera is needed to know precisely what you’re dealing with. The camera is fixed on the end of a flexible access rod and the drain is closely inspected to identify the problem. The problem may, for example, be identified as weathering of external taps that may be affecting water flow. For more information on this, read our ‘outside tap fitting costs’ page.
Patch lining is the less intensive alternative for full drain lining. It’s suitable when a contractor wants to treat only one spot, which may be confined in terms of size and location. Patch lining follows the same process as drain lining, only that the former uses a single piece of lining material, not an entire cylinder. The section of the lining material is pushed gently to the target spot hand then an air balloon is used to patch it to the damaged pipe. The patch cures with time, glueing to the pipe’s surface, thus repairing or solving the problem.
