MAXPLUG is a quick-setting cement-based mortar that instantly stops running water from cracks, fissures, holes or other openings in concrete and masonry. It is non-shrink and sets within three to five minutes depending on the temperature. Once MAXPLUG sets, it adheres perfectly to the substrate. It only requires water for mixing.

  • Sealing of leaks in concrete surfaces, solid masonry and other sound substrates with active water flow through cracks and holes.
  • Emergency repairs on concrete water pipes. For broken concrete pipes, MAXPLUG will even work when the concrete pipes are under hydrostatic pressure.
  • Emergency plugging of gas leaks.
  • Sealing of concave corners and working joints, filling the grooves with MAXPLUG in the shape of a cone.
  • Anchoring of bolts and other accessories that require immediate use.
  • Stopping running water in basements, tunnels foundations and sewers under hydrostatic pressure.
  • It is a suitable maintenance material for homes and industry.


A quick setting hydraulic cement that instantly stops running water from cracks, holes or other openings in concrete and masonry.

  • Does not shrink, or become weak due to its exothermic reaction.
  • MAXPLUG increases in volume, giving a permanent seal in areas where there is flowing water.
  • Its quick setting-time from 3 to 5 minutes can be controlled, either sped up or slowed down, by adding warm or cold water.
  • Setting may even be instantaneous by adding hot water during warm weather.
  • Will set underwater.
  • Does not contain chlorides.
  • Easy to use.
  • Its mechanical properties are similar or higher than concrete.
  • Non-toxic. It can be used in contact with drinking water.
  • One kg of MAXPLUG/Maxgrip fills about 0.615-0.620
    l, depending on the amount of mixing water. (approximately
    1.62 kg/l).
