Kajima Corporation of Tokyo, Japan, has contracted with Geocomp of Acton, MA, to provide engineering services on the construction and evaluation of an “Ice Wall” groundwater barrier around the Fukushima Nuclear Power Plant. Geocomp has subcontracted with Moretrench American Corporation, North America’s largest ground freezing contractor, to assist with their construction experience.
Geocomp and Moretrench will provide Kajima with assessments of comparable ground freezing experiences from around the world to help share technological achievements to enhance the design, construction and performance of the Fukushima Ice Wall. They will assist in the evaluation of the design, construction quality assurance and performance testing. This team brings experience from some of the largest and most challenging ground freezing projects performed in North America.
Artificial ground freezing is the process of converting the subsurface pore water to ice to produce a strong, water-tight barrier. It has been used for over one hundred years in the construction of deep shafts, excavations and groundwater barriers in the mining and civil construction industries.
Geocomp is a privately held company that specializes in geostructural design, performance monitoring of structures and active risk management services for the construction industry. Moretrench is an employee owned company the provides geotechnical design and contracting services.
