Description
NIKKEN KOGAKU CO., LTD. is a civil engineering company specializing in the development, manufacture, sale, and leasing of products for coastal and marine infrastructure. The company's core offerings include a range of high-stability, wave-dissipating concrete blocks (e.g., RAKUNA-IV, SANREN GRASP) and armor blocks (STONE-BLOCK) used for revetments, seawalls, and artificial reefs. It also operates a steel formwork manufacturing and lending business. A key differentiator is its strong focus on research and development, evidenced by over 800 patent applications and collaborations with universities. This has led to innovative solutions like Environmentally Active Concrete (EAC), designed to support marine ecosystems. The company primarily serves government agencies, local governments, and construction firms.
