Typical Applications

  • Deep section patch repair using form pour or pump, all orientatons, section depth between 50-200mm, and requiring high strength, between 30-60 MPa


  • Maximum compatibility with concrete compressive strength, 30-60 MPa
  • Unique dual expansion system offers an extremely high level of control of plastic and long-term drying shrinkage
  • Low alkali content minimises risk of alkali-silica reaction
  • Excellent bond to concrete substrates without independent primer
  • Very low permeability provides excellent protection against carbon dioxide and chlorides
  • Exceptional flow allows pumping or pouring into restricted locations
  • Self-compacting nature eliminates honeycombing and displaces air without vibration
  • Suitable for electro-chemical repairs
  • Pre-bagged to overcome site-batched variations - only the site addition of clean water is required
  • Contains no chloride admixtures
