Hydraux Premium F125

Water-reducing superplasticizer for high-flow concrete


A high-range water reducer that makes concrete flow into the form instead of having to be worked in — fewer honeycombs, fewer hollow spaces, and strength gains rather than losses.

Use it for

  • Beams, columns, and precast concrete with congested reinforcement
  • Any pour where honeycombing is a risk
  • Reducing water content without losing workability
  • Concrete that must flow into complex formwork

Why this one

  • Flows into the mould
    Highly flowable concrete that fills the form rather than bridging over gaps
  • No honeycombs
    Eliminates the hollow spaces and voids that form when stiff concrete is poured
  • Strength gains
    Water reduction means a stronger mix, not just an easier one
  • ASTM C-494 Type F
    Meets the high-range water-reducing admixture standard
  • Powder admixture
    Simple to dose and store on site
  • Proven side by side
    Betonit’s own comparison shows the difference with and without F125
