PALTEM（High Performance Products）
PALTEM (Pipeline Automatic Lining SysTEM) is a type of trenchless technique for rehabilitating buried pipelines—such as those carrying potable water, sewage, agricultural water, gas, telecommunications signals, or electricity—without having to dig up the pipe. This environmentally friendly method minimizes damages to pipeline surroundings while supporting lifeline infrastructure, helping procure safe water, and ensuring that residents can continue to live in their neighborhoods.
Contributing to Maintaining Essential Utility Services Using Safe and Secure Pipeline Rehabilitation Technology
PALTEM (Pipeline Automatic Lining SysTEM) is a type of trenchless technique for rehabilitating buried pipelines—such as those carrying gas, potable water, sewage, agricultural water, telecommunications signals, or electricity—without having to dig up the pipe. Since the development in 1980 of the hose lining method—a technology developed exclusively in Japan—the PALTEM Division has been supplying the materials required for the trenchless rehabilitation industry. PALTEM continues to contribute to the maintenance of these essential utility services.

Making the Most of Core Technologies Involving Fiber and Resin
Going beyond materials employed in our PALTEM methods, we are contributing to society by developing a variety of products that make full use of our core technologies for skillfully creating products using fiber and resin.
UNILINE is a type of hose developed for use in indirect cooling systems for underground electric power cables. It withstands high pressures, while being lightweight for easy transportation and handling during installation. Moreover, it can be supplied in lengths of up to 600 meters.
This is an H-shaped earth-retaining material made of GFRP (glass-ﬁber reinforced plastic) that can be cut by a shield tunneling machine. This environmentally friendly product signiﬁcantly reduces the need for soil stabilization and can be expected to reduce costs and shorten construction times.
