Most pipelines, whether gas, water, sewerage, technological networks are already aging and infiltrations and leaks are occurring more and more often. These infiltrations and leaks in the pipelines of the companies must – for safety and economy reasons – be rehabilitated very quickly …

In order to recondition these pipes, the so-called NO DIG technologies have become more and more important in recent years – that is, reconditioning technologies without stripping.

For a still statically portable pipe, the reconditioning by the “re-lining” method is from the current point of view of the technique, the most qualitative method of reconditioning the pressure pipes and the pipes with gravitational flow.

The “re-lining” technology originates in Japan where a technical solution was sought to avoid leaks from damaged pipes due to frequent earthquakes in this area. The “re-lining” process solved this problem.

In a very short time, technology has developed and is today one of the most advanced reconditioning methods for gas, oil, drinking water and wastewater pipelines and for those in the chemical industry.
The method we present introduces a hose provided with a chemically resistant inner foil on the inside and one or more layers of felt on the outside, in the pipe to be rehabilitated. The felt layers are impregnated with a thermo-reactive resin, which will harden during the installation of the tube, at the same time taking the shape of the host pipe, forming a new pipe with special qualities.
