It involves lining the inside of a drain with a UPVC lining which then bonds to the inside of the pipe.
The Benefits of Drain Lining
There are numerous benefits to lining drains over replacing them.
• No digging or trenching required which reduces cost & hassle.
• The lining itself forms a barrier against roots getting into the pipework.
• Drain lining is cost effective as it’s cheaper than replacing pipes.
• Improved flow rates.
JD Drains Drain Relining Process
• We start with a CCTV survey of the drain to identify the damaged section.
• We then clean and de-scale the affected section of pipework with a combination of electro-mechanical machining and high pressure water jetting.
• The relining sleeve is then installed by way of air inflation. This sleeve cures over a period of up to three hours per run.
• Once the curing period is complete, the inflation tube is removed.
• The new relined section is then cleaned to remove any excess resin solution.
Cured In Place Pipe Lining (CIPP Lining)
The Cured In Place Pipe (CIPP) lining technique was invented in the early 1970’s.
It’s also known as the no-dig option, although sometimes digging may be required to get to a point where the liner can be installed.
The liner is pulled into the pipe then cured under pressure. Over the years, techniques and installation methods have developed, however the end result is a new pipe, inside an old pipe, without any expensive digging or trenching required.
CIPP lining has become a popular method of permanent structural repairs to a drain that runs from 100mm up to 900mm, whilst causing minimum site disruption.
Patch Lining & Repairs
Patch lining allows localised lining to repair smaller sections of damage – this can be useful where a full lining would be unnecessary.
Drain patch repairs are typically around 50mm – 100mm. For damaged areas that are larger than this, we’d generally recommend lining the full run.
