    MasterSeal 590 is a fast setting mortar to plug active water leaks in concrete and masonry


    MasterSeal 590 is a blend of hydraulic cements, well graded sands and additives supplied in dry powder form. It requires only the addition of clean water to produce a ready-to-use, ultrarapid setting, plugging mortar. 

    Where is MasterSeal 590 fast setting mortar applied?

    • Stops active water or seepage under pressure through joints, cracks and holes in concrete or masonry, where a normal mortar would be washed away and resin would not bond. 
    • For sealing cracks and construction joints in reservoirs and other water-retaining structures. 
    • For instant sewer connections. 
    • For rapid anchoring of bolts, conduits, pipes, railings, sanitary equipment, etc. 
    • Joint filling, pointing between concrete segments in concrete and brick tunnels, sewage systems, pipes and mines. 

    What are the advantages of MasterSeal 590?


    • Chloride-free, will not promote corrosion of reinforcement. 
    • Expands as it sets to ensure a permanent watertight seal. 
    • Mechanical characteristics similar to concrete.
