Labor-saving! Underground beam section "Pipe-in-sleeve T-type" water immersion countermeasures and waterproofing.
Efficiently streamline on-site work with prefabrication! Achieve shorter construction periods and improved quality.
[Coming Soon] An upgraded version of the beloved "Pipe-in-Sleeve"! "Pipe-in-Sleeve T-Type," abbreviated as PIS-T. In contrast to the PVC sleeve, a through pipe made of FEP has been pre-filled with waterproof material (sealant) at the factory, making it prefabricated. The T-type further features a "drainage PVC flange" welded with PVC material to the outer layer of the PVC sleeve. This method replaces the ring-shaped or band-shaped waterproof material on the outer circumference of the PVC sleeve, responding to strong requests from construction companies. <Features> ■ Excellent waterproofing due to prefabrication: Promotes flood prevention and water resistance ■ Labor-saving at construction sites! Reduces worker burden and prevents troubles in advance! ■ No skilled techniques required! Simplifies complex tasks! ■ Flexibility to accommodate individual design specifications of projects! ■ Improved work efficiency, standardized quality, and enhanced maintenance! [For Designers and Contractors] FEP pull-through, bell mouth terminal installation, etc., can be arranged according to individual site specifications! Additionally, it is equipped to handle unexpected leaks! A versatile and highly adaptable product that also incorporates maintenance and serviceability. *For details, please request a catalog from "Contact Us" or view the PDF data from "Download."

Applications/Examples of results
*R2.6 National Public Works Publication "Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings" *R3.4 (Public Foundation) Japan Sewerage New Technology Organization "Promotion of Waterproofing (Final Version)" The adoption of these measures in construction work is rapidly increasing. "Pipe-in-Sleeve (PIS)" <Excerpt from Adoption Records by Local Governments> (Statistics from January to March 2026) - Osaka Prefecture ●● City) Communication equipment and other construction work related to the expansion of ●●●● - Shizuoka Prefecture ●● City) Electrical equipment construction for the (tentative name) ●● District Center in fiscal year 7 - Kyoto Prefecture ●● City) Electrical equipment construction related to the new building construction of ●● City Hospital (Section 1) - Kanagawa Prefecture ●● City) Electrical equipment construction for the expansion of ●● Elementary School building No. 1, among others Due to the recent shortage of construction workers and skilled labor, while "easy installation" is possible, there are also materials/methods that underestimate waterproof performance, leading to an increasing trend in leakage problems with underground beams in recent years. To prevent leakage accidents from resulting in large-scale repair work later on, we advocate for the adoption of Pipe-in-Sleeve (abbreviated as PIS), which combines both "labor-saving at construction sites" and "ensuring the waterproof performance of buildings."

JECA Fair 2026 Product Competition | Japan Electrical Contractors Association Encouragement Award〈Recipient〉
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.

We have published a FAQ for the waterproof sleeve "Pipe-in-Sleeve" for underground and outer wall use.
The "JECA Fair 2026 74th Electrical Industry Exhibition" will be held soon from May 27 (Wednesday) to May 29 (Friday) at Tokyo Big Sight. We are planning to showcase at the booth of Furukawa Electric Co., Ltd. "Waterproof Sleeve for Underground Outer Walls - Pipe in Sleeve" We have compiled the inquiries we received regarding the product launch and have created an FAQ, which we have started to publish. Since last year's JECA Fair, we have received numerous inquiries and requests from various fields, for which we are truly grateful. We kindly ask you to take a look. Thank you.
