PIS-T

*R2.6 Publication of National Transportation Document "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 is rapidly increasing in construction projects. "Pipe-in-Sleeve (PIS)" <Excerpt of Adoption Records from Local Governments> (Statistics from January to March 2026) - Osaka Prefecture ●● City) Communication equipment construction related to the expansion of ●●●● and others - 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 construction of a new building at ●● 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 of leakage problems in underground beams in recent years. To prevent leakage accidents that could lead to 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 "maintaining the waterproof performance of buildings," as well as Pipe-in-Sleeve T-type (abbreviated as PIS-T).
