Interline CIPP is a polyester resin saturated felt liner that is installed by inverting the liner within the host pipe and then curing it using hot water. Because the lining is in a soft state when it is installed Interline CIPP liner will conform to the shape of the host pipe making it suitable for installation in non-circular pipes (e.g. ovoids, egg-shapes) and circular pipes with bends and changes in direction. After cure the ends of the liner are trimmed at the access chambers and the ends are sealed to the access chamber surfaces using a high strength epoxy.

Lateral connections to the main are robotically re-opened and, if specified, are sealed in a separate process using Interfit.

The strength of the liner is dependant on the liner wall thickness and can be selected to suit design or structural requirements. When cured Interline CIPP has sufficient strength to resist pipe loadings and provides a smooth, chemically resistant internal surface which restores or often improves the hydraulic capacity of the original pipe. The end result is a renewed asset with an expected service life of at least 50 years.

Interline CIPP can structurally rehabilitate pipes constructed of common pipe materials including brick, concrete, vitrified clay, AC, glass reinforced plastic.
