Disaster Mitigation Products

Non-Frame Method™ stabilizes the slope through interaction between natural ground and reinforcing materials, by utilizing the natural slope vegetation and driving a number of relatively short rockbolts (rod-type reinforcement) along the slope.

Steel Slit Dam™ allow harmless sediments to flow downstream under normal conditions and secure the sediment volume until occurrence of a debris avalanche. They also contribute to maintain the riverbed level in downstream areas and prevent recession of the riverbank.
