The expansion-type rock bolt made of reinforcing steel pipes, developed by K.F.C. Co., Ltd., contributes to the longevity of tunnels.

When high-pressure water is injected using a dedicated high-pressure water injection system, the expansion section of the rock bolt inserted into the ground expands along its entire length, securing it to the ground. By providing a male thread at the mouth, it becomes possible to tighten the lining concrete with a nut, which is expected to enhance the effectiveness of ground support. 【Accessories】 Injection adapter High-pressure water injection system for expansion Anti-loosening nut "K nut" Protective pipe for lining concrete Multifunctional G type (tip cap detachable type)

Making the adsorption layer construction easier. No need for mixing work or quality control of the adsorption layer on site. Slope construction is also easy.

The "Padem Sheet" is a jointly developed product by Toppan Printing Co., Ltd. and ES Research Institute, Inc. It is a sheet filled with the adsorbent "Interface SMV#IR," which adsorbs harmful substances such as arsenic and selenium contained in the soil. In the adsorbent layer method that adsorbs and treats heavy metals, it is used as a base layer instead of the adsorbent layer. 【Standard Construction Procedure (when laying one layer)】 1. Ground leveling 2. Installation of protective mat (on the base surface side) 3. Installation of Padem Sheet 4. Installation of protective mat (on the contact surface side with excavated soil) 5. Transportation and leveling of protective soil *For more details, please refer to the materials. Feel free to contact us with any inquiries.

Inorganic injection-type anchor

The SR injection capsule is a capsule filled with special cement that is immersed in water to create a properly water-ratioed setting mortar. It is an inorganic injection-type anchor that can be filled into drilled holes by using a dedicated cartridge.
