Point repairs of sanitary sewage systems
In addition to the trenchless repairs in the technology where the CIPP "long liners" are used, we also make point repairs of conduits along lengths less than between two access points (two drains), using the short liner method called “packer". The “short liner” repair method is a technique for carrying out repairs on the drains with diameters of 200 to 600 mm where glass fibre liners, 0.5 m to 1.0 m long, saturated with epoxy or silicate resin mixtures are inserted along the length of the pipe.
Point repairs executed by our company also include the sealing of the inclusion of sewer lateral lines to the mainline, using the top hat type fittings or so called “packer-and-top-hat” type fittings, saturated with epoxy or silicate resin mixtures. The sewer lateral lines are sealed with top hat fittings or packer-and-top-hat fittings for connections of DN100-DN250 mm in diameter.
