- The set foam is a rapid foaming hardening type that cures in about 60 seconds. - The set foam reaches almost final strength in about 30 minutes, allowing the tunnel to be used immediately. - After curing, there is almost no volume change such as expansion or contraction. - Foaming starts about 12 seconds after mixing, resulting in minimal penetration into the ground behind the lining concrete and leaks from cracks, leading to less waste. - Due to its rapid foaming hardening type, there is little escape, allowing for complete filling of cavities. - It foams and hardens even underwater, and its independent bubbles provide excellent water-stopping properties. - The cured material has a low density, resulting in a smaller load acting on the lining concrete surface. - Analysis results and numerous achievements confirm that it does not cause water quality pollution and is safe.

"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 and produce reaction products upon the supply of moisture even after drying and hardening, filling newly occurring fine cracks and other voids after construction. These reactions densify the voids in the surface layer, including the depths of cracks, and suppress the intrusion of water and various deterioration factors over the long term. 【Features】 ■ Turns the structure into a waterproof body: Improved durability ■ Freedom in design: Fewer constraints ■ Significantly shortens construction time ■ Minimal aging deterioration: Easy management ■ Excellent environmental performance: High safety ■ Abundant track record: Long-term peace of mind *For more details, please download the PDF or contact us.
