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!

Based on the Ministry of Land, Infrastructure, Transport and Tourism's "Basic Plan for the Longevity of Infrastructure (Bridges, Roads, Public Housing, etc.)," we aim to achieve both the longevity of infrastructure and labor-saving at construction sites as a "two birds with one stone." 【Proposed Projects】 - Public facilities (public congestion, infrastructure-related facilities, etc.) - Seismic isolation structure high-rise buildings 【Effects of Implementation】 - Longevity through non-corrosive sleeves - Improved work efficiency through labor-saving/lightweight materials - Total cost reduction (materials + construction costs) Polyethylene is a stable material that fundamentally does not use plasticizers, and its lifespan is approximately 30 to 50 years if not affected by ultraviolet rays. In contrast, PVC resin containing plasticizers begins to deteriorate in about 10 years, potentially leading to reduced flexibility and cracking. EP sleeves contribute to the longevity of construction and infrastructure. "'Lightweight' accelerates 'efficiency' on site!" A sleeve material that combines high pressure resistance and direct workability with "lightweight." In particular, compared to rigid PVC pipes weighing about 53 kg/m, EP sleeves weigh about 17 kg/m, ensuring a significant weight difference that guarantees improved work efficiency and labor-saving at construction sites. *For details, please request a catalog from "Contact Us" or view the PDF data from "Download."

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."

"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.'

The trend of installing rainwater storage tanks in "underground pits" rather than "outdoor buried" locations is increasing in urban areas due to site constraints, construction feasibility, maintenance management, and the advancement of flood control measures. Utilizing underground pits contributes to the effective use of above-ground space and reduces risks during disasters, but the durability of the installed equipment becomes crucial. Our all-resin pedestrian access "EP Sleeve" provides a highly reliable solution to these challenges through the use of non-corrosive materials and extended lifespan. 【Usage Scene】 Pedestrian access during the installation of water tanks in underground pits. 【Benefits of Introduction】 - Extended lifespan due to non-corrosive material "ALL polyethylene material." - Improved efficiency in cleaning and maintenance operations. * Of course, it also contributes to "labor-saving" with lightweight resin during the construction process! * For details, please request a catalog from "Contact Us" or view the PDF data from "Download."
