Ideal for waterproofing the structural bodies of facilities such as parking lots, rooftops, basements, and water tanks.
"CS-21" is a concrete modification agent that penetrates hardened concrete through application, generating stable reaction products (CSH-type crystals) with calcium components in the concrete to fill voids. Additionally, the unreacted main components dissolve upon moisture supply even after drying and solidification, producing reaction products that fill newly occurring fine cracks and other voids after construction. Through these reactions, the voids in the surface layer, including deep cracks, are densified, suppressing the intrusion of water and various deterioration factors over the long term. [Features] ■ Improved durability of the structure as a waterproof body ■ Freedom in design with minimal constraints ■ Significant reduction in construction time ■ Easy management of minimal aging deterioration ■ Excellent environmental performance and high safety, etc. *For more details, please download the PDF or feel free to contact us.
