Drain lining is also known by a few names; No-Dig Technology, Professional patching or in-situ repairs. Simply put it is as if you are fitting a brand new pipe inside an old existing pipe. It is the fastest and most cost effective way to repair a damage drain or sewer. It involves installing a felt lining which is impregnated with special resin. This is then expanded with an air bladder and the resin laden lining bonds with the old pipe work to effectively give it a second skin to repair and prevent leakages from breaks or cracks in the pipe. Little if any disruption needs to occur to the existing drainage system / pipes, no digging or excavating is needed. It is all done through the existing inspection chambers / manholes. Full lengths, half lengths or even individual sections can be selected through CCTV inspection and repaired. Bends, curves and offset joints are no problem for this flexible lining to negotiate and repair. The lining used is extremely durable, it may be quick and cheap to apply the fix but the result is a repair that will last a very long time. The lining is suitable for sewers, culverts, vertical down pipes and many other applications. It is built to resist the most aggressive chemicals and can withstand extremely high temperatures. Drain relining benefits include:
- No costly excavation of surfaces needed
- Minimum disruption and down time to your business / home

- All types of pipe material can be considered for renovation
- Lining systems available for runs containing diameter changes
- Runs of of up to 550 to 600 metres relined in one continuous length
- Increased flow rates
- Prevents tree root infestation
- The process is accepted by Local Authorities, Loss Adjusters, Surveyors, Civil Engineers and Architects etc.
With the quick cure resin we use, in many cases the pipe can be used again in the same day the repair was applied. Call our 24-hour response line to ask our team about pipe lining, pipe repairs or any other “no-dig” solutions.
