UR-S101 & S102

UR-S101

UR-S101 is a medium-density polyurethane foaming sealing agent used to stop leakage caused by cracks in subways, underground utility tunnels, and other concrete structures. When injected, it reacts even with a small amount of water and expands more than 10 times, forming a closed-cell structure that prevents water or moisture penetration while minimizing shrinkage.

UR-S102

UR-S102 is a rigid polyurethane foaming sealing agent designed for leakage control in subways, underground utility tunnels, and other concrete structures. Upon injection, it reacts with small amounts of water and expands more than 20 times, forming a closed-cell structure that blocks water penetration with minimal shrinkage.
