“Repair Method CN6.0”

The Repair Method CN6.0 has realized the repair of RC water tanks, which until now was considered impossible, by using unique materials and equipment based on a new conception, obtained from the construction of more than 100 tanks, to densify the fine interior of the concrete and restore it to its original highly alkaline state. This method extends the service life of RC water tanks. Furthermore, it enables carbon dioxide emissions to be reduced by approximately 60% compared with new construction, and by approximately 97% if demolition is included, as well as a significant cost reduction of approximately 85% (600 t class RC water tank).
