C.I.P.P. (Cured In Place Pipe) Full Length Lining
Whichever method is chosen, the soft tube is inflated back tight to the wall of the existing host pipe where, when inverted, it adheres to the pipe wall and resin migrates through cracks and fractures sealing them. The tube, having been inflated using air, water or steam is, (when using Thermo Cure Resin), heated to the required temperature for a pre-determined length of time. Other systems involve the introduction of a "Light Train" that uses "Ultra Violet" light to cure the resin that is sensitive to that.
When this has been achieved the Liner can be struck and brought back into use in a very short time span with minimal disruption to services or the environment.
It is clear from even this small amount of information that it is impossible to give prices for an average linear per meter as there is no such thing as "Average" when talking about CIPP liners. Each is an individual.
We only use approved Epoxy or Polyurethane resin unless otherwise stated or requested.

Flow Characteristics Are Significantly Improved
It can be used to slip line where the diameter of the host pipe is reduced but the flow characteristics are significantly improved, replacing size for size or even up sizing where suitable and an increased capacity is required.
There are numerous systems and methods but as a general description, steel rods are inserted through the drain to be replaced. To the end of these, a "Splitter" and "Sizing" cone are fitted and behind these the new pipe. Hydraulic Rams, developing incredible force, then pull the assembly through the old pipe bringing the new pipe in behind. The old pipe is burst out into the surrounding ground where it forms part of the support of the new drain in the now compacted soil.
This method of replacement has full Industry Approval and has been used for many years but only now is it becoming available for smaller works.
