We will be determined to be one of top construction materials companies that deliver satisfaction to customers.
Our artificial inorganic compound is a material-saving eco-friendly waterproofing agent, which, unlike current membrane-type methods, can adequately obtain required qualities by putting it into and mixing it either in the batcher plant or a truck agitator when making concrete and thus enhance the efficiency of the material management in the state key industries.

Our Company specializes in the production of "Powdered waterproof admixture" and "Corrosion-inhibitor and water proof admixture" which enable the simplification of construction methods by mixing the artificial inorganic compound at the time of making concrete to provide both waterproofness and corrosion resistance to concrete itself at the same time.

Out Company has remarkable growth with the development and production of water proof admixture suitable for tap water systems and sewage systems, railway and subway facilities, maritime structures, port facilities, underground structure etc since 1998 when it was founded. And it has strengthened its stance and reputation as an environment-friendly enterprise that puts out VOCs-free, eco-friendly products through the development of environment-friendly technologies.

In addition, our Corrosion-inhibitor and waterproof admixture has been accredited as an eco-friendly construction material that is in compliance with the environment-related Standards of the Ministry of Environment and has been filed for a patent domestically as well as in the USA, and China for the first time in the world. Furthermore, it has been awarded the NET certificate for the first time in the construction industry to prove to be the best quality product in Korea.

Based on permanent waterproofing and antirust performances of our waterproofing admixture, Jangsan CM will take the lead in this area with the concrete method that is one notch higher than others.
