Precast concrete with excellent material barrier properties and resistance to dissolution and leaching.
Many of the concretes excavated from ancient Roman sites and the Dadiwan ruins in China are believed to have chemically stabilized and improved durability through carbonation, allowing them to exist healthily. "EIEN" is a new concrete with excellent performance that reflects the findings of ancient concrete research in modern cutting-edge concrete technology. 【Features】 ■ It has a lifespan of ten thousand years. ■ By densifying the near-surface through carbonation curing and improving material shielding and resistance to leaching, its durability has been enhanced. ■ Due to its excellent material blocking and leaching resistance, it suppresses the rise in pH levels of the surrounding environment.
