Production will start" Polyethylene sleeve / access hole (access port) "EP-Sleeve

High-density polyethylene pedestrian passage (pedestrian opening) "EP-Sleeve" - Lightweight, high strength, and a proposal for labor-saving! [Coming soon]

Polyethylene Personnel Access Hole (Personnel Access Port) EP-Sleeve In response to everyone's requests, we are excited to announce its upcoming release! ■ High Pressure Strength: The smooth double structure of the corrugated inner surface makes it resistant to impact and external pressure, providing excellent flat strength. ■ Lightweight Material: Compared to rigid PVC pipes, it is lightweight. It enhances transportation and work efficiency, contributing to "labor-saving" at construction sites. ■ Rust Resistant: Made of high-density polyethylene, it is safe and secure for installation in water areas! ■ Cold and Chemical Resistant: Compared to rigid PVC pipes, it is suitable for installation in extremely cold regions and shows no degradation against most chemicals. "Lightweight accelerates efficiency on site!" A material that combines high pressure strength with the lightweight that leads to direct workability. In particular, rigid PVC pipes weigh about 53 kg/m, while polyethylene sleeves weigh about 17 kg/m, showcasing an overwhelming weight difference! We guarantee a significant improvement in work efficiency at construction sites. Furthermore, it also reduces the burden on workers and lowers the risk of accidents, contributing to enhanced safety! *For details, please request a catalog from "Contact Us" or view the PDF data from "Download."

[Official Release] Waterproof Sleeve for Underground Walls "Pipe-in-Sleeve" (Abbreviated as PIS) Reducing Labor at Construction Sites! Enhancing Waterproof Performance of Buildings!

■Recently, our "Pipe-in-Sleeve," showcased at the JECA Fair 2025, is officially released with great anticipation.■ In the underground wall section (underground beam sleeve), we have pre-treated the PVC sleeve and the outer space (gap) of the FEP with "waterproof treatment" at the factory, making it prefabricated for the site. On-site, there is no need for cumbersome work; after installing the PIS, basically only joint connections are required. It ensures stable waterproofing! Achieving work efficiency and promoting flood prevention and water resistance. This is an innovative and advanced product for underground beam sleeve construction. <Features> ■ Excellent waterproof performance [Flood prevention and water resistance promotion] ■ Proposal for labor-saving at construction sites ■ Adaptable to individual project design specifications ■ Improved work efficiency, standardized quality, and enhanced maintainability [To Designers and Contractors] FEP pipe through-piping, bell mouth terminal installation, connection of different pipes (AQ type), and various connection parts of Eflex can be arranged according to the specifications of each construction site! Furthermore, it can also respond to unexpected water leaks! It combines maintenance and serviceability, making it a versatile and highly adaptable product. (Feel free to request drawings as well) *For details, please request a catalog from "Contact Us" or view the PDF data from "Download"

"Civil Engineering Watching - Infrastructure Encyclopedia: Collection of Civil Engineering Structures" is a portal site for images and information about civil engineering structures that form social infrastructure facilities. We have recently published photos and articles about the "Saale Valley Bridge." The "Saale Valley Bridge" was constructed at the border between Saxony-Anhalt and Thuringia, in Bad Kösen, Naumburg. Boasting an impressive height of up to 60 meters, this structure spans a total length of 1.2 kilometers and a width of 12.5 meters, harmoniously blending with the surrounding landscape designated as a nature reserve. In addition to the "Saale Valley Bridge," various civil engineering projects, photos, and articles related to civil engineering are also featured, so we hope you will take a look.

Many customers wish to obtain technical standards conformity certification (Giteki) and construction design certification to use imported Wi-Fi products domestically. However, since radio laws differ from country to country, it is important to note that adjustments to transmission power may be necessary to comply with Japan's radio law. Among these, we will introduce products that require special attention, specifically those compatible with IEEE802.11ax (Wi-Fi 6).

We have introduced the Majesta Fragrance commercial diffuser to a fitness gym located in the city. Gyms and sports clubs tend to trap sweat and humidity, making them spaces where odor issues can easily arise. That’s why "scent design (branding)" that dramatically changes the overall impression of the space is highly effective. - The diffuser being used is the [MF-01]. It is a stylish tower-type diffuser available for a monthly fee of 8,800 yen (tax included). This model is space-saving and blends well with any interior. - The scent being diffused is [Forest Green]. It is a refreshing fragrance that blends the crispness of bergamot with the natural scent of green, creating a clean and pleasant atmosphere. It enhances concentration during exercise while providing a refreshing and comfortable space. A free trial installation is available. "I don’t know what scent would suit my gym." "I want to try out the different scents available." For such stores, Majesta Fragrance offers a free trial installation. If you are considering space branding or odor control, please feel free to contact us.

We will be exhibiting at the 133rd Annual Meeting of the Geological Society of Japan. In addition to introducing services such as sediment surveys and chemical analysis of samples, we will also showcase products like core samplers. Please feel free to ask the booth staff about new graduate recruitment and experienced hires for the 2028 fiscal year. We look forward to seeing you all. Date: September 13 (Sunday) to September 15 (Tuesday), 2026 Location: Kanazawa University, South Area of Kakuma Campus (1st floor of the Natural Science Lecture Building, Kanazawa City, Ishikawa Prefecture)
