Labor-saving! Underground beam section "Pipe-in-sleeve T-type" water immersion countermeasures and waterproofing.

PIS-T

EPJ

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."
