Business Areas

• Trenchless Full Repair (CIPP) Business: Korea Litech Development's core business model is trenchless full repair of water and sewer pipes using the CIPP (Cured-in-Place Pipe) method. This method involves inserting a resin-impregnated tube into an aging pipe without excavating the road and curing it to form a new pipe.

Products

• TPLS Method (Trenchless Full Repair): The TPLS (Trenchless Pipe Lining System) method is a trenchless full repair technology that involves inserting a tube-shaped liner impregnated with thermosetting resin into an aging pipeline and curing it with steam or hot water. This method reinforces the structural strength of the existing pipe and extends its lifespan semi-permanently.
• TPLS-WR Method: The TPLS-WR (Wetout in place & Roll insertion) method is a new construction technology developed by Korea Litech Development, which is an in-situ impregnation and roll-insertion pull-type trenchless full repair method for sewer pipes.
• UV Light Irradiation Robot and Automatic Curing System Method: The trenchless full repair and reinforcement method for sewer pipelines using a UV light irradiation robot and an automatic curing system is a technology that involves inserting a UV light irradiation robot into a tube liner and curing it with an automatic curing system.

Special Notes

• Possession of Proprietary New Technologies and Patents: Korea Litech Development holds numerous new environmental technologies (TPLS method) and new construction technologies (TPLS-WR method, UV light irradiation robot method, etc.). Its technological prowess is recognized through over 10 patents related to trenchless repair of water and sewer pipelines.
• Environmentally Friendly Construction: By using a trenchless method to repair aging pipelines without road excavation, environmental problems such as traffic inconvenience, noise, and dust are minimized. This contributes to extending the lifespan of social infrastructure.
• Participation in Public Institutions and Local Government Projects: With local governments and public institutions as its main clients, the company actively participates in BTL projects and local government-commissioned construction projects in regions such as Busan and Gyeongsangnam-do.
