Underground exterior wall sleeve - Labor saving "Pipe-in-Sleeve" water immersion measures/waterproofing

Due to the impact of the Middle East conflict, the supply of JIS standard rigid PVC pipes (PVC pipes) is unstable. However, domestically produced recycled PVC pipes (NON JIS), which use high-quality recycled materials, provide a "reliable choice" that ensures stable supply and reasonable pricing. This is an ideal circular material for the coming era, meeting economic, environmental, and supply stability simultaneously.

JECA Fair 2026 74th Electrical Construction Industry Exhibition Will be held at Tokyo Big Sight from May 27 (Wednesday) to May 29 (Friday), 2025. The "Waterproof Sleeve for Underground Exterior Walls - Pipe-in-Sleeve," which was submitted by Furukawa Electric Co., Ltd., has been awarded the "Encouragement Award from the Japan Electrical Construction Association." "Innovation in Underground Beam Sleeve Construction!" We deliver a PVC sleeve with a pre-treated "waterproofing" process applied in the factory, integrated with electrical conduits (E-Flex) in a prefabricated state. At the construction site, there is no need for troublesome "waterproofing," and after installation, only joint connections are required, improving work efficiency and achieving "labor-saving." Furthermore, it provides stable waterproof performance for flood prevention and water resistance construction! It enhances the waterproof performance of buildings, balancing work efficiency and construction quality! This is all thanks to the support of developers, design firms, general contractors, subcontractors, and trading companies. We will continue to strive towards the next stage. We sincerely appreciate your continued support.

As always, our well-known "Non-drying Polyolefin-based One-component Water Stop Putty TometaroⓇ" and the "Underground Wall Waterproof Sleeve Pipe-in-Sleeve (abbreviated as PIS)," which has been well-received since its launch last year, will be exhibited at the "JECA FAIR 2026 - 74th Electrical Equipment Industry Exhibition" held at Tokyo Big Sight. This exhibition is the largest comprehensive electrical equipment exhibition in Japan, showcasing new products related to electrical equipment, tools, measuring instruments, software, systems, and more, as well as introducing construction techniques, improving construction efficiency, academic presentations, and initiatives for reforming work styles in the electrical equipment industry. The exhibition will be at the booth of Furukawa Electric Co., Ltd. We sincerely look forward to your visit.

A new innovative product for the underground beam sleeve construction is about to be released! Introducing the upgraded version of the "Pipe-in-Sleeve" that you have come to love! "Pipe-in-Sleeve T-type," abbreviated as PIS-T. The T-type features a "water drainage PVC flange" welded with the same material (PVC) to the outer layer of the conventional PIS PVC sleeve. This method serves as an alternative to the ring-shaped or band-shaped water-stopping material on the outer circumference of the PVC sleeve, responding to the strong requests from construction companies. Achieving both work efficiency and construction quality! Stay tuned for the official launch!
