Cured In Place Pipe (CIPP)

Inversion Pipe Relining, commonly referred to as CIPP (Cured In Place Pipe), is one of the many types of trenchless pipe relining restoration processes used for rehabilitating damaged pipelines. It involves the use of a textile liner tube and liquid pipe relining resin. Once installed inside the sewer or stormwater pipe, the combination of materials cure, providing a tight-fitting structural liner inside the existing pipe providing a much stronger and more cost-effective permanent alternative to destructive excavation and trenching techniques traditionally used for sewer or stormwater pipeline repair or replacement.

Non-Destructive Technology


Considered non-destructive and non-disruptive, this type of trenchless pipe relining technology involves the inversion of a felt tube saturated with a special two-part pipe relining resin using compressed air through the inside of the existing host pipe. After the liner tube has made its way through the sewer or stormwater line, it is then inflated, and the resin cured with either ambient air or hot water to create a tight fit against the inside of the host pipe creating a new pipe within the old pipe. Given the right conditions long lengths of pipe with diameters between 50mm and 400mm can be relined in as little as a single day in many cases.

Benefits Of Inversion Pipe Relining 

Reline through any pipe material such as earthenware, PVC, concrete and cast iron 

Pipe relining with 3D liners enables us to line any change in pipe size within the pipe 

Inversion relining can be used to reline both horizontal and vertical pipes from either end 

Drainage excavation can take days whereas pipe relining only takes hours in most cases 

The ability to reline long lengths of sewer or stormwater drains in one operation  

Inversion relining can negotiate multiple pipe bends such as 5, 15, 30, 45, 60 and 90 deg 

Using thermosetting or heat curing resins gives us the ability to install longer liners

Installed liners are 4 times stronger than conventional PVC sewer pipes
