CRALEY Liner - Trenchless pipe relining LIPP
CRALEY Liner™ (formerly known as BreezeLiner™) enables the fast and cost effective re-lining of waste-water ducts, at the same time installing fibre cable into the infrastructure.


The CRALEY Liner™ solution uses a new and patented technique for pipe re-lining: LIPP™ (Laminate in Place Polymer), and offers a radical, lower cost, quicker to install and greener alternative to traditional Cured-in-Place Polymer (CIPP) systems using chemical resins with hot water, steam or UV curing.
CRALEY Liner™ consists of multiple HDPE thermo-plastic polymer layers in concentric arrangement. This makes for a highly flexible structure that can be flat-packed: making storage and transportation easy. The flexibility of the material also means it can easily be pulled down a manhole and into a duct, negotiating any bends within a pipe.


Once CRALEY Liner™ has been installed a special PIG (Pipe Inspection Gauge) travels through the pipe and fuses the interface between the laminate layers in-situ. This technique ensures a close fit to the duct wall. The use of dual-oriented polymer and alternative molecular alignments in successive laminate layers creates and exceptionally strong completed lining finish.

CRALEY Liner™ offers a number of advantages over other lining technologies.


  • Costs are reduced by 50% and installation is 300% faster than CIPP resin liner systems

  • No toxic resins or chemicals are used to create the liner in the pipe

  • No heat or UV curing is required

  • HDPE Thermo-plastic liner, requires no “setting time”

  • Can be installed quickly – typically up to 300metres per day

  • Can easily be removed and materials recycled

  • Can be installed in pipes ranging from 150mm (6”) to 300mm (12”) diameter

  • Flexible when installed: allowing for slight physical movements that occur in a pipe system over time

  • Helps to resolve issue in areas of root ingress, water and silt ingress and effluent egress

  • Smooth inner-lining surface improves flow velocity by up to 30% and reduces surcharge level by 20%

  • Can increase the asset lifespan by at least 50 years

  • Allows installation of a fibre optic duct at the same time as re-lining the pipe

  • Fully free from Bisphenol A (BPA) and no leaching of environmentally hazardous materials
