Environmentally friendly, non-separating underwater concrete that solidifies without clouding.
Hydrocrete was born in 1979 as the first non-segregating underwater concrete in Japan, enabling the construction of underwater structures with thin and wide components, reinforced concrete components, and highly reliable components, which were difficult to achieve with conventional underwater concrete. It has been used in many projects, including ports, fishing ports, rivers, and dam construction. Additionally, long-term durability has been confirmed through specimens exposed to the sea since 1985.

Company information
Our company is engaged in civil engineering projects in marine, coastal, and inland areas. In particular, we utilize unique technologies such as asphalt mats and underwater non-segregating concrete for caisson friction enhancement, shore protection against scour, waterproofing and water-stopping works for marine pollution prevention, and renewal of marine structures. Additionally, we conduct various geological surveys, underground facility investigations, underground facility and magnetic surveys, cavity investigations, unexploded ordnance surveys, various measurements, marine surveys, testing measurements, and hydraulic model experiments. We also carry out research, planning, design, technical guidance, and other engineering and consulting services related to these construction projects.
