SDライナー工法協会 List of Products and Services

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.

The "SD Liner Method" is a technique for constructing new rehabilitation pipes inside existing sewer pipes without excavation, specifically for aging sewer systems. There are three types of rehabilitation methods: individual installation of lateral pipes, individual installation of main pipes, and integration of lateral and main pipes. Additionally, there are two construction methods available: the formation method and the inversion method, allowing for the selection of the most suitable method based on site conditions. 【Features】 - The thermosetting resin used is vinyl ester resin, which has excellent chemical resistance. - There are two types of resin-impregnated substrates: - SD Liner II (glass reinforced type): uses acid-resistant glass fibers as the substrate. - SD Liner (standard type): uses non-woven fabric as the substrate. *For more details, please download the PDF or feel free to contact us.
