Adeka Ultraseal

Description: Water-swelling rubber elastic type sealing materials


Adeka Ultraseal Made in Japan. It is an innovative hydrophilic rubber waterstop. Ultraseal stop water by compression of the rubber and by hydrophilic action (expansion pressure) when the seal is exposed to water, It will expand to fill in any gap or void within the limits of its expansion when exposed to water.



  • Controlled expansion with exposed to water
  • Easier and More Economical to Install
  • Stop water leakage by volume (expansion) pressure.
  • Stable expansion ability in a variety of water conditions.(Example seawater, cement water.)
  • Excellent elasticity
