Fast setting mortar to plug active water leaks in concrete and masonry and for quick covings and patches prior to membrane application.
MasterSeal 590 is a fast setting cementitious mortar which stops active water leaks through joints, cracks and holes in concrete or masonry. It is successfully used as a seal for construction joints or floor joints prior to basement tanking with MasterSeal membranes.
MasterSeal 590 is the safe solution for stopping water leaks and for quick covings and patches prior to the application of cementitious and resin-based membranes. It is formulated without the use of chlorides. Therefore, dose not promote corrosion on concrete reinforcement and expands during hardening process, ensuring the effective blockage of water by compressing the substrate.
MasterSeal 590 is the necessary complement in all waterproofing application solving connections and completing the MasterSeal waterproofing system. It will stop leakages where a normal mortar would be washed away and resin would not bond. Its quick hardening allows the immediate application of the waterproofing membrane.
