The "DK Bond Method" is a slope construction technique implemented directly on the source of falling rocks, aiming to suppress the fall of floating stones and boulders. This method involves stabilizing unstable rocks by using an adhesive (DK Bond Mortar) to bond them to stable bedrock, thereby integrating and stabilizing them. In addition to integrating unstable rock masses with the ground, it also has the effect of preventing weathering and erosion, which are causes of rock falls. 【Features】 ■ Does not compromise the landscape ■ Can be applied in areas where large machinery cannot access ■ Not affected by the size or shape of the target rock masses ■ Expected adhesive strength can be achieved within 7 days ■ Can be used in conjunction with other construction methods *For more details, please download the PDF or feel free to contact us.

Our company is a certified construction agent for Rhino Japan Co., Ltd. in the Hokuriku and Koshinetsu areas. We have received training as construction supervisors for the "Polyurea Resin Spray Method" and our trained personnel carry out the construction. Polyurea resin is an advanced coating material derived from polyurethane, characterized by its quick-drying properties, curing in about 5 seconds, and demonstrating impact absorption performance. The standard film thickness is approximately 2mm, allowing for immediate use after construction is completed, significantly reducing the construction period compared to conventional methods. 【Features】 ■ Ultra-fast drying with a curing time of as little as 3 seconds and complete curing in 24 hours, enabling rapid service resumption. ■ Proven wear resistance with values ten times better than good results in the Taber abrasion test. ■ Thin film thickness, typically between 1mm and 3mm, forming a robust coating layer. *For more details, please download the PDF or feel free to contact us.

The "Bio-Organic(R) Method" is a technique that covers slopes (earth, concrete, rock) with a bag-like mat filled with plant seeds and vegetation substrate, protecting the slope in harmony with nature. Since the vegetation substrate is contained within the bag-like mat, there is no erosion from rainfall, frost, or freezing, and no runoff from spring water or melting snow, ensuring the establishment of vegetation substrate on the slope. In addition to protecting slopes, it is also used to protect riverbanks. 【Features】 ■ Greening earth and weathered rock ■ Greening hard rock with few cracks ■ Greening steep slopes ■ Greening in snowy and cold regions *For more details, please download the PDF or feel free to contact us.
