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."

[Adoption Results] Waterproof Sleeve for Underground Exterior Walls / Pipe-in-Sleeve TM

Please rest assured that pipe-in-sleeve has been adopted in public sector projects for 'flood prevention construction' and 'waterproofing promotion initiatives.'

This is the record of adoption (delivery) for the well-known underground wall waterproof sleeve "Pipe-in-Sleeve." For underground wall sections, we apply "waterproof treatment" in advance at the factory to the outer space (gap) between the PVC sleeve and the FEP, and then prefabricate it for the site. There is no need for cumbersome work at the construction site; after installation, it basically requires only joint connections. It ensures measures against water ingress and waterproofing stability! Achieving work efficiency and labor-saving! <Features of Pipe-in-Sleeve (abbreviated as PIS)> ■ Excellent waterproofing through prefabrication: Promoting measures against water ingress and waterproofing ■ Labor-saving at construction sites! Reducing the burden on workers and preventing troubles in advance! ■ No skilled techniques required!

Public/Private Facilities: Proposal for Pipe-in-Sleeve Flood Prevention by Design Company

A serious and practical proposal for "flood prevention measures"!

In recent years, there has been an increasing trend of intensified disasters such as typhoons. The Typhoon No. 19 in 2019 caused flooding in the underground electrical facilities of a tower mansion, leading to a prolonged disruption of infrastructure, which became a significant social issue. Since then, the flood prevention guidelines proposed by the national and local governments have recommended waterproofing measures for underground power supply facilities and entry points as essential. "Pipe-in-Sleeve (abbreviated as PIS)" involves waterproofing PVC sleeves and FEP pipes at the factory and prefabricating them, ensuring the sound waterproof performance of buildings while simplifying on-site work and contributing to shorter construction periods. 【Flood Prevention: Suggested Facilities】 * Public facilities (city halls, ward offices, police stations, libraries, etc.) * Hospitals and welfare facilities * Residential facilities (high-rise and medium/small scale apartments, etc.) * Transportation infrastructure facilities (railways, airports, highways, etc.) 【Flood Prevention: Suggested Applications】 * Underground beams/exterior wall penetration (underground penetration/power cable entry) <Implementation Effects> * Improved stable waterproof performance of buildings * Labor saving (reduction of worker burden) * Shortened construction period * For details, please request a catalog via "Contact Us" or view the PDF data from "Download."

Effective Use of Pits: All-Plastic Polyethylene Manhole 'EP Sleeve'

All resin: polyethylene pedestrian passage! Non-corrosive resin pedestrian passage "EP sleeve" [Installation of fire extinguishing tank and fire water tank]

"The 'underground pit' is a valuable shelter for 'water.'" In urban and commercial areas, land is a precious space that is desired to be rented or sold at a higher price, even by one tsubo (approximately 3.3 square meters). When planning construction, installing fire-fighting tanks or fire water tanks above ground can impact land utilization. There is a growing trend of utilizing pits for 'fire-fighting water tanks,' which are mandated by fire laws and regulations, and 'fire prevention water tanks' for the community. Since underground pits are protected by the building's foundation (a strong concrete structure), the risk of the tank itself being destroyed during a disaster is the lowest. Of course, installing them above ground or in exclusive areas reduces effective space (for sale or rent), but utilizing pits allows for the entire above-ground floor to be effectively utilized. [Utilization Scenes] In the installation of 'fire-fighting water tanks' and 'fire prevention water tanks,' there are no hygiene concerns since they are not for drinking water storage, but the corrosion of installed items and longevity are challenges. [Effects of Introduction] - Non-corrosive material 'ALL polyethylene material' for pedestrian access - Improved efficiency in cleaning and maintenance work *Of course, lightweight resin during the construction process also contributes to 'labor-saving'! *For details, please request a catalog from 'Contact Us' or view the PDF data from 'Download.'

【Apartment Building】 Underground Beam Sleeve: Power Cable Entry _ Sound Waterproofing

Streamlining on-site work through prefabrication! Achieving both shorter construction periods and improved quality simultaneously!

【Enhancement of Waterproof Performance of Buildings】【Labor-saving Construction of Underground Beam Sleeves】 The entry point for power cables in underground exterior walls of collective housing (RC construction), such as condominiums, is the most critical area directly linked to the risk of flooding during disasters. However, it is a "hard-to-see, invisible part," making it difficult to visually confirm after construction. This often leads to variations in construction quality. Although waterproofing work is carried out, there are not infrequent troubles where flooding into the underground pit has already progressed by the time defects are discovered. What is Pipe-in-Sleeve? It is a prefabricated sleeve that has been waterproofed in the factory using PVC sleeves and E-flex (FEP). It ensures the healthy waterproof performance of buildings and contributes to labor-saving on-site work and safe construction. ■ Proposed Facilities Collective housing, etc. (Waterproof Cast Iron Pipe VE Plan) ■ Implementation Effects * Stable waterproof performance of buildings * Labor-saving (reduction of workers' burden) * Shortened construction period <Of course, it also contributes to disaster prevention> ● JECA Fair 2026/Product Competition: Received the Encouragement Award from the Japan Electrical Construction Association (under the name of Furukawa Electric Co., Ltd.) ● * For details, please request a catalog from "Contact Us" or view the PDF data from "Download."
