Due to the area which is (sand and rock) it was necessary to repair using this technology, assured the council.
The work consists mainly in the interior of the pipe casing by a sleeve and injecting resin to harden forming a waterproof film.
The cooling process takes approximately 8 to 10 hours.

And the inconvenience to citizens by the invasion of field work are minimized.
The new line has the following qualities:
- No joints, resulting in a sealed tube and devoid of creases .- Improving the hydraulic characteristics of the existing pipeline with the new smooth surface .- Ensures high resistance to aggressive wastewater .- Stops embedding roots. - The use of non-polluting materials ensures compliance with environmental requirements.
