  • Block Environment Business

We also conduct mold leasing for products such as the vertical wave-dissipating block “Igloo,” the eco-friendly type block “Aquareef” and the new type of covering block “Permex” as well as the wave-dissipating block represented by the “Tetrapod.”

For the adoption of each block, the Company provides various technological and design services, such as preparation of cross-section diagrams and positioning diagrams with CAD and proposals for required tonnage via simulations. Additionally, we will make proposals on technologies and products that are considerate of co-existence and harmony with organisms and scenery of shores, rivers, and surrounding areas.
