The durability of concrete has dramatically improved! [NETIS registered] We are exploring new possibilities for concrete that continues to regenerate semi-permanently.
Zypex is a concrete modification material that densifies the structure by promoting the growth of cement crystals in defects such as voids and cracks within the concrete, thereby blocking deterioration factors like water and enhancing waterproof performance to improve the durability of the structure. ■Mechanism of Concrete Densification■ The mechanism of densification by Zypex involves mixing concentrated powder with a specified amount of clean water to create a paste, which is then applied or sprayed onto the surface of the concrete. This allows catalytic compounds to penetrate deep into the concrete, promoting the growth of new cement crystals at the capillary voids and crack interfaces, thereby densifying the concrete structure itself. The depth of modification through crystallization can vary depending on the concrete conditions, but it can extend to over 30 cm in a moist environment.

basic information
Characteristics of Zypex ■ Waterproofing + Increased Durability ■ Concrete structures treated with Zypex block water by promoting the growth of cement crystals in capillary voids and cracks, which are the causes of water leakage. Therefore, Zypex demonstrates high performance as a waterproofing material. Additionally, it simultaneously prevents the intrusion of harmful substances and reduces moisture content, leading to effects such as the suppression of carbonation, rust prevention, salt damage prevention, suppression of alkali-silica reaction, and further prevention of freeze damage, thus creating added value that enhances the durability of concrete. ■ Self-Healing of Cracks ■ Concrete treated with Zypex can self-heal cracks as cement crystals repeatedly grow semi-permanently at the crack interface.

Company information
Our company was founded in 1958 and specializes in underground special civil engineering works such as underground continuous walls, underground obstacle removal, ground improvement, and pipeline construction. In recent years, we have expanded our business operations to include slope work and construction. There is a growing social demand for securing the natural environment, seismic reinforcement, liquefaction prevention, restoration of structures, and urban redevelopment, which have become pressing issues in recent years. In response to these social needs, we have developed seismic reinforcement and liquefaction countermeasure methods such as the "Ultra Multi-Point DP Method" and the "High Grip Grout Method." For structural restoration, we utilize our in-house developed restoration method called "Suiheikun," and for urban redevelopment, we are conducting research and development of new methods such as the "Hiro Work Kmigty Method," "Bauer Method," and "Super Top Method," aimed at underground obstacle removal. Additionally, as part of our eco-friendly initiatives, we are researching and developing methods that use bubble drilling fluid to reduce industrial waste, striving to contribute to society through high-quality construction and services. We aim to continue responding to the needs of the times by deploying a variety of specialized techniques and uniquely developed methods.
