The latest pipe relining technology means blocked or damaged underground pipe work can be repaired without having to excavate and replace the damaged pipe work. Essentially it is a trenchless process. A lining (essentially a woven fibreglass hose with a thin plastic film on the outside) is inserted down into the existing pipe. The new lining is forced towards the inner surface of the old pipe, where it is hardened and creates a brand new pipe inside the old existing pipe.
Inversion pipe relining is a system used for the repair of longer distances of pipe (normally over 2 meters). Inversion uses air pressure to invert a resin, impregnated liner into an existing pipe through a pressurised drum. Hot water is then circulated through a boiler to advance the curing process.
Patch repair, is the system used for repairing small sections of pipe (normally up to 2 metres). It inflates a rubber packer (bladder) that is sleeved in a resin impregnated liner and allowed to cure.
Key Benefits of Relining
- No digging up of pipe work is needed. This saves time and costs
- Work around not through concrete floors, driveways, paths, bathroom floors, gardens
- Quicker than conventional methods
- Can be used on pipe bends
- Less expensive than other repair methods
- Relining is suitable for domestic, industrial and commercial pipe work
- It can repair all types of pipe work including septic, stormwater, sewer and chemical pipes
- Strong and reliable pipework helps protect the environment and public health from sewer leakage
- Less wasteful because old pipes are not being dug up and discarded
- Helps the local environment & landscaping by avoiding the necessity for destructive trench digging
