With the increase in building height and seismic resistance improvements, the width of beams has been increasing. - Increased amount of rebar (main bars and stirrups) in beams - Spread of high-strength concrete - Long-period and wind sway countermeasures - Increased load on beams due to the slimming of columns (design requirements) - Improved workability (especially with high-strength concrete) As a result of these factors, recent high-rise buildings show an increase in "beam width," particularly for underground beams, which tend to be significantly thicker, with widths exceeding 1,000 mm not being uncommon. Therefore, waterproofing work for the outer circumference of cable conduits penetrating through sleeves in underground exterior wall sections (underground beams) is extremely challenging. Due to the current shortage of construction workers and skilled labor, the waterproof performance of buildings is becoming increasingly unstable. Thus, we propose the following: **Application Scenarios** - Piping work for underground beams - Sleeve penetration work for exterior walls - Pulling through FEP pipes **Benefits of Implementation** - Significant reduction in construction time - Reduced burden on workers - Stabilization of quality - Decreased risk of water leakage

In the construction industry, there is always a demand for shorter construction periods and improved quality. In particular, the waterproofing treatment of the underground beam exterior wall is the most critical construction area for eliminating leakage risks and enhancing the safety of the building's power supply. Traditional methods often require complex waterproofing work on-site, leading to longer construction periods. However, the Pipe-in-Sleeve (PIS) system simplifies on-site work by prefabricating PVC sleeves and FEP pipes in the factory, contributing to shorter construction times. [Usage Scenarios] * Underground beam/exterior wall penetration * Underground penetration/power cable entry [Benefits of Implementation] * Labor-saving (reducing the burden on workers) * Shorter construction periods * Improved waterproof performance [For Designers and Contractors] FEP pull-through, bell mouth terminal installation, etc., can be customized to individual site specifications! Additionally, it can handle unexpected leaks! It is a versatile and highly adaptable product that also incorporates maintenance and serviceability. ● Be sure to check out the introduction video on YouTube, "Tome Taro Channel." * For more details, please request a catalog from "Contact Us," or view the PDF data from "Download."

[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!

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."
