Lightweight polyethylene pedestrian passage (pedestrian opening) "EP Sleeve"! Labor-saving!

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."

Tometaro Non-curing Water Stop Material [Rodent Control Measures - Rodent Prevention NETIS Registered]

"Shut out water and mice" Stop Water Material TometaroⓇ "Mouse prevention measures at the same time!" Recently, water disasters have been increasing dramatically. Implement mouse prevention along with water stop measures!

Non-drying polyolefin-based one-component water-stopping putty agent TometaroⓇ TometaroⓇ offers a proposal for "environmental control" against rodents. Structures have various environments that attract rodents (such as pipe penetration areas), and as long as these environments exist, rodent control will continue indefinitely. Therefore, we recommend "TometaroⓇ (water-stopping material)" for easy, safe, and highly sustainable pest control! After years of research, it has been proven to provide "water intrusion measures (waterproofing) - leak prevention and leak repair" along with "humane rodent control." <Features of Tometaro for Rodent Control> ■ "Basically no maintenance required" It does not contain any repellent chemicals. TometaroⓇ physically blocks the entry points. (This does not apply if there is already a history of rodent intrusion into the building.) ■ "Humane" Since no chemicals are used, there is no skin irritation during handling. ■ "Rodent control along with water intrusion measures (waterproofing)" TometaroⓇ, a non-hardening water-stopping putty agent originally developed for water intrusion measures, addresses both issues simultaneously. *For details, please request a catalog from "Contact Us" or view the PDF data from "Download"

Stop Water Putty TametaroⓇ Ser. Premixed Mortar Hatsureeru

TometaroⓇ optional products, mortar that can increase water resistance, and it's easy to chisel! 【Water infiltration measures / waterproofing】

For projects involving the construction of renewable energy, flood prevention, and waterproofing, we propose safe and long-lasting water-stopping solutions. In addition to the optional products for the water-stopping putty TometaroⓇ, which prevent leaks at cable penetration points and recommend the "two-layer filling" method, we have developed additional options based on the requests of design companies and contractors, such as "I want to solidify the bell mouth opening" or "I want even higher water-tight performance." Our company recommends the "two-layer filling" method using "backup material + non-drying water-stopping material TometaroⓇ," but when filling the third layer opening with a fully cured finishing material, please use it in conjunction with TometaroⓇ and Hatsureeru. As the name suggests, Hatsureeru allows for easy and safe chiseling after filling when re-running cables. *For details, please request a catalog from "Contact Us" or view the PDF data from "Download"
