The foundation of urban regeneration! Introducing a construction method that uses vinyl ester resin with excellent chemical resistance!
This construction method involves forming a new rehabilitation pipe inside an existing sewer pipe without excavation, specifically targeting aging sewer systems. We offer two methods categorized by the type of base material used for rehabilitation: the "SD Liner Method <F+VE>" which uses non-woven fabric as the base material, and the "SD Liner II Method <G+VE>" which uses acid-resistant glass fiber as the base material. Both methods utilize a thermosetting resin that is a vinyl ester resin with excellent chemical resistance. 【Features】 ■ SD Liner Method <F+VE> - The inversion method allows for integrated rehabilitation - Uses non-woven fabric as the base material ■ SD Liner II Method <G+VE> - Acid-resistant glass fibers are evenly arranged in both the axial and circumferential directions - Uses acid-resistant glass fiber as the base material *For more details, please refer to the PDF document or feel free to contact us.

Company information
This construction method involves the non-excavation installation of a new rehabilitation pipe inside an existing deteriorated sewer pipe. - The rehabilitation method allows for three types of construction: standalone installation of the connection pipe, standalone installation of the main pipe, and integration of the connection pipe with the main pipe. - Vinyl ester resin, which has excellent chemical resistance, is used for the thermosetting resin. - There are two types of substrate for resin impregnation: standard non-woven fabric and glass-reinforced type. - The construction methods include the formation method and the inversion method. The optimal method can be selected based on site conditions and other factors. Please feel free to contact us.
