CABLOC® are crosslinked polymers with water binding groups. In their dry form these polymers are insoluble in water but highly swellable. They protect power and communication cables from damage through penetration of water. Penetrating water is absorbed immediately and is firmly bound through swelling. Defects and damaged parts are sealed effectively, thus preventing further penetration of water.


  • Rapid swelling properties
  • High gel strength and mechanical stability
  • Non-ageing
  • Resistant to micro-organism
  • Easy to use
  • Non-toxic
