The Technological Center for New Developments in Trenchless Technologies offers pipeline rehabilitation by means of the SPR technology (installation of a liner from a spirally wound pipe). The technology is applied for rehabilitation of brick, concrete, cast-iron, fiberglass, plastic and other sewer pipes, low pressure water mains, rain water pipes and culverts with diameters of up to 3000 mm, providing structural rehabilitation even to severely damaged pipelines. The technology is based on the principle of “in-place” pipe production from continuous plastic (PVC or HDPE) factory manufactured strip of high stiffness and low weight. Pipe installation is implemented without any excavations, as the existing shafts are used. The technology guarantees the complete elimination of infiltration and exfiltration, improvement of the hydraulic properties and wear-resistance of pipelines and extends the life of sewers by 50 and more years.
