Main Function:

  • Very low permeability to chloride and water intrusion.
  • Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete).
  • Increased abrasion resistance on decks, floors, highways and marine structures.
  • Superior resistance to chemical attack from chlorides, acids, nitrates and sulfates
