NRM List of Products and Services

We would like to introduce the rock bonding construction method called "SP Bond Method." By simply mixing with a specified mixing liquid, high-quality polymer cement can be produced. We offer a range of products including the cement-based rock bonding material "SP Bond Filler," and the mortar bonding reinforcement material "SP Bond Emulsion," which enhances the physical properties of mortar such as impact resistance, flexural strength, abrasion resistance, and adhesion. For more details on other products and methods, please feel free to contact us. 【Features】 <Cement-based Rock Bonding Material: SP Bond Filler> ■ Main components: Ordinary Portland cement, natural aggregates ■ High-quality polymer cement can be produced simply by mixing with a specified mixing liquid. ■ High adhesion performance can be achieved by mixing with a diluted solution of SP Bond Emulsion at a 1:2 ratio with water. *For more details, please refer to the PDF materials or feel free to contact us.

The "FDC Rope Hanging Method" is a construction technique that involves securing large floating rocks and areas at risk of peeling and falling with anchors and wire ropes on a slope, where rockfalls are a concern. By installing a new device called a tension manager, which incorporates springs at both ends of the wire rope, a semi-permanent tension is maintained in the wire rope. This strongly presses the target rock mass against the slope, aiming to stabilize the rock mass. 【Features】 ■ Amplifies frictional force ■ Efficiently stabilizes rock masses on slopes ■ Can accommodate large rock masses with minimal materials ■ Excellent economic efficiency ■ Shortens construction time and enhances safety *For more details, please refer to the PDF document or feel free to contact us.

The "NPF Net Fence" is a high-energy absorption type rockfall protection net (pocket type) equipped with a rockfall energy absorption device. During a rockfall impact, it has the function of protecting ropes and anchors from shock due to its cushioning capability. Additionally, the support rope (commonly referred to as the vertical rope) that is attached to the posts is fixed with anchors, which enhances the stability of the wire mesh section (in this method, the fence) and reduces snow accumulation on the wire mesh. The large space between the mesh and the slope makes it less susceptible to the effects of snowfall, and it can also be used in conjunction with avalanche prevention fences and other structures. *For more details, please download the PDF or contact us.*
