Our company is a green company that specializes in the production of “PPS Powdered Waterproofing Admixture” and “PPS Anticorrosive and Waterproof Admixture.” They are intended to be mixed, when making concrete, to simultaneously maximize anticorrosion and waterproofness in reinforced concrete itself, which will achieve the durability of the concrete and ensure integrated construction methods.

When it comes to bridges, surface cracks resulting from structural movement and driving load allow water, moisture, and other harmful substances to penetrate into concrete and develops corrosion in iron rods, which eventually leads to damage to the structure due to the scaling and exfoliation of the coating of concrete. Likewise, SOC-related structures incur not only direct costs such as repair and maintenance expenses but indirect costs such as traffic control and preparation of detours. Therefore, design and construction of high durable concrete are required to provide resistance to corrosion in reinforced rods caused by cracks.

Our PPS admixture, an artificial inorganic compound, is a material-saving, eco-friendly waterproofing agent because, unlike current membrane-type methods, it can adequately lend required qualities by mixing it either in the batcher plant or a truck agitator to make multipurpose concrete. This concrete will maximize the life of structures so as to save construction materials and reduce the production of wastes.

All employees of JANGSAN CM will do their utmost to satisfy our customers with multipurpose, high-quality products and technology that can achieve waterproofness, anticorrosion and reduce cracks, and we will try to build structures of first grade durability in preparation of global warming that can last 100 years.
