[Official Release] Waterproof Sleeve for Underground Walls "Pipe-In-Sleeve" (Abbreviated as PIS) Reducing Labor at Construction Sites! Enhancing Waterproof Performance of Buildings!

■Recently, our "Pipe-in-Sleeve," showcased at the JECA Fair 2025, is officially released with great anticipation.■ In the underground wall section (underground beam sleeve), we have pre-treated the PVC sleeve and the outer space (gap) of the FEP with "waterproof treatment" at the factory, making it prefabricated for the site. On-site, there is no need for cumbersome work; after installing the PIS, basically only joint connections are required. It ensures stable waterproofing! Achieving work efficiency and promoting flood prevention and water resistance. This is an innovative and advanced product for underground beam sleeve construction. <Features> ■ Excellent waterproof performance [Flood prevention and water resistance promotion] ■ Proposal for labor-saving at construction sites ■ Adaptable to individual project design specifications ■ Improved work efficiency, standardized quality, and enhanced maintainability [To Designers and Contractors] FEP pipe through-piping, bell mouth terminal installation, connection of different pipes (AQ type), and various connection parts of Eflex can be arranged according to the specifications of each construction site! Furthermore, it can also respond to unexpected water leaks! It combines maintenance and serviceability, making it a versatile and highly adaptable product.

■Development Concept■ "Labor-saving in Construction Sites" In modern construction projects, the aging of skilled workers and the departure of young people have led to a constant demand for both work efficiency and construction quality. By utilizing "prefabrication technology," we aim to solve the persistent issues at construction sites and extend the lifespan of buildings. Furthermore, we are developing groundbreaking products that also incorporate maintenance and upkeep performance! "Enhancing the Waterproofing Performance of Buildings" At each construction site, the narrow gaps between the pit, underground beam sleeves, and penetrating pipes require "waterstop treatment" as mandated. According to the "Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings" issued by the Ministry of Land, Infrastructure, Transport and Tourism and the Ministry of Economy, Trade and Industry, we are advocating for the development of products that possess safe and reliable waterproofing performance! <Areas of Demand> Underground beam sleeves (subterranean outer wall sections) for various construction projects <Countermeasure Types> - Flood prevention construction: Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings by the Ministry of Land, Infrastructure, Transport and Tourism / Ministry of Economy, Trade and Industry - Promotion of waterproofing: Concept of waterproofing for sewer facilities by the Ministry of Land, Infrastructure, Transport and Tourism, etc. 【Inquiry Ranking】 1st: Medical Facilities 2nd: Accommodation Facilities 3rd: Commercial Facilities 4th: Educational Facilities 5th: Offices (High-rise)
