Terraline™ is used for the slip lining technique that uses appropriate lengths of threaded pipe, which can easily be assembled in confined spaces such as manholes or small excavations.

Terraline™ is manufactured from PE80, an extremely tough, high strength material used world-wide for sewer and sewer relining applications.

Using predetermined lengths of Terraline™ pipe, the sewer is relined by assembling the pipe manually at one end and either pushing or pulling it into position using simple winching equipment.

The robust 'flush thread' provides a smooth internal and external surface for easy installation and low friction coefficient. The joint seal is made by an ‘O’ ring joint.

# Provides type II structural lining
# Low coefficient of friction
# Well established renovation technique
# Wide range of lengths and diameters
# Lightweight for easy handling
# Excellent chemical resistance
# Available in diameters 63-630mm
