Patch lining – No-dig pipe repair and reconstruction

The most technologically advanced systems used
 Patch lining diagram and example

How does patch lining work?

A piece of resin-impregnated glass-fibre matting is placed onto an inflatable packer and positioned. Once in the desired location, the packer is inflated and held in place for the duration of the curing process (approximately 2 hours). This leaves a watertight and permanent pipe repair solution.

Fast and effective drain and sewer repair

Cleanline WWS offer the very latest in no-dig sewer reconstruction via the most technologically advanced patch lining systems. Patch lining provides a fast, less intrusive and cost-effective drain repair solution compared with traditional excavation methods. We work across Liverpool, the North West and the UK.

Why choose patch lining?

  • It’s accurate: Patch liners can be used to refurbish localised drainage problems, so there’s no need to replace the entire pipe
  • It’s cost-effective: Patch lining uses trenchless, or no-dig technology to repair the pipe, so is less intrusive
  • It’s fast: There’s no need for messy and disruptive excavation; the job is completed fast, meaning less fuss for you
  • Solutions to problem drainage:such as under buildings or in no dig areas such as production lines.

Our specialist drain liner can withstand most corrosive chemicals which is discharged into your drainage systems. The patch is wrapped around special equipment that can be inflated, and inserted into the damaged drain. It is then expanded onto the existing pipe and left to set hard. After curing the equipment is deflated and removed, leaving the patch in place.

Flexible sewer repair solutions

Cleanline WWS can patch line pipes ranging from 100 to 1200mm in diameter. So whatever your project, you can rest assured we will find the solution. Simply get in touch to discuss your requirements with our experienced team.

Patch liners are used as a chosen method of repair where defects are evident within a certain section of sewer or drainage system. The patch liner system is generally used when there is a particular isolated defect or there are multiple defects within a shorter section area of pipe work.

These areas can be remotely accessed generally through one point of entry such as an existing manhole chamber. Patches can also be overlapped to achieve rehabilitation over greater distances where access may be an issue to install a full length liner.  Inflatable packers are used to allow flows to continue to pass through the system whilst the patch liner has been inserted in the defective areas allowing the continued use of the system. This reduces the impact on customers, allowing continued use of their internal facilities.
