CIPP is a form of trench less repair solution, also known as ‘no-dig’ technology. Commonly CIPP involves insertion of a Resin impregnated reinforced liner through an existing pipeline, the liner is the cured insitu to form a seamless, jointless pipe within an existing pipeline, restoring the strength and serviceability of the pipe without he disruption that would be caused by the traditional method of excavation. CIPP is less disruptive to the environment to the public, and is more economic in almost all cases, than Open Cut Excavation. CIPP methods can be used to rehabilitate sanitary sewers, storm drains and pressure pipelines for water, gas and process effluents. We are able to accommodate circular pipes from 50mm to 1800mm diameter Firstly the pipe is cleaned and any debris removed. In the case of damage and deformation to the pipe, local repairs may need to be performed, ready for the CIPP process.

CIPP RELINING
Once this has been completed the process involves a needle felt or glass fibre liner being impregnated with resin. Using either pinch rollers or a wet out table to ensure the liner is fully saturated. The liner is then installed into the pipe using either an inversion or drag in method. The drag in method is most commonly used for small diameter pipes using ambient cure resin, in combination with a calibration hose or inflation tube, that is left in place until the liner is cured.
The inversion method makes use of an inversion drum or sluice to fill the liner with water or air. Thus forcing the liner to invert and be pushed into the host pipe. Where as the drag in method, which requires access to both ends of the rehabilitation, pulls the impregnated liner into place. Effectively the liner is pushed into the host pipe, and thus only a single access point is required for installation, this method is suitable for use with ambient, heat assisted, and hot cure applications. Once the liner is completely cured, the ends are cut as appropriate, any laterals reinstated and a new pipe is formed within an existing pipeline, You Need A Plumber will then finish by surveying the works and evidencing through CCTV survey.
