Take immediate control of water ingress with the Soudal Soudaplug st rapid-setting mortar. This cementitious plugging mortar instantly stops running water and active leaks in concrete, stone, or masonry, even under high hydrostatic pressure. Formulated to set within minutes, it cures reliably even underwater, allowing you to execute emergency repairs in basements, manholes, and pipe penetrations without delay. Because the composition is completely chloride-free, it will not corrode embedded steel rebars in reinforced concrete. Supplied in a robust 25 kg bucket, this fast-curing compound gives you the volume needed to seal cracks, joints, and cavities with a lasting watertight finish.
