Sika Fastplug-102 rapid leak-stopping plug

A chloride-free, fast-setting cement mortar in powder form. Mixed with water, it becomes a permanent water plug that stops leaks and seepage through concrete and rock, and through joints between concrete and steel, in basements, pools, tunnels, culverts, subways and dams. It bonds well, does not crack, does not corrode steel bars and is non-toxic once hardened.
