CIPP Lining (Cured In Place Pipe) is a trenchless technology that is used to provide a new structural lining inside a gravity sewer that has failed due to cracking, movement or joint failure. The development of UV cured EcoCIPP Lining was a major development in trenchless technology, cutting pollution, noise and installation times, whilst maintaining sewer capacity.



Pipe bursting is a trenchless technology that is used to replace an existing sewer pipe. Pipe bursting can also be used to upsize an existing pipe to increase capacity. Pipe bursting is one of several sewer renovation methods that use trenchless technology. Perco operates several pipe bursting techniques including Expandit pipe bursting, Maxiburst Rod Pulling, Miniburst pipe bursting and manhole bursting.




Perco is the leading auger boring specialist in the UK. Auger boring is a trenchless technology where the auger boring rig removes ground using a cutting head and auger flights. Piloting is the first part of the auger boring process, where an accurate line and level is established for the auger boring process.
Guided auger boring is the preferred method for installing gravity sewers to accurate line and level. Guided auger boring can achieve accuracies of +/- 40mm over a 50 metre shot. Guided auger boring is approved for pipe and UTX installation under live rail. Guided auger boring can install up to 50 metres per day. Guided auger boring can install pipes from 150mm to 1000mm. Guided auger boring can install lengths of up to 100 metres in a single shot.





Unguided auger boring is a traditional auger boring technique. Unguided auger boring can install pipe lengths of up to 300 metres in one shot. Unguided auger boring can install pipe diamteres from 150mm to 1200mm. Unguided auger boring is ideal for pip installations where supreme accuracy is less important. Unguided auger boring is often used to install pumping mains for potable and raw water as well as sewerage.











EPROS patch liners provide localised sewer repair for gravity sewers with 50 year guarantee.
