Anti-washout Admixture

 EUCON AWA is a ready to use liquid admixture designed to prevent the loss of cement and fine aggregate during the placement of underwater concrete. EUCON AWA is a blend of different powerful ingredients and colloidal agents that act primarily on the water preventing the cement paste from washing out during casting under water. EUCON AWA provides superior slump retention while greatly reducing the environmental impact due to cement wash out in below water applications.

Features & Benefits

  • Minimal environmental impact due to cement washout
  • Eliminates the need for expensive de-watering during underwater construction
  • Greatly reduces or eliminates concrete bleed water
  • Superior slump retention
  • Does not effect water demand when slump is maintained
  • Easily metered with standard admixture dispensing equipment


  • Underwater bridge repair
  • Dam repair below the waterline
  • Underwater grouting and mortar application
  • Damming underground rivers/lakes in mining operations
  • Anti-segregation aid for use with lightweight and heavyweight aggregates
  • Reduction or elimination of concrete bleed water for use with fast track construction

Specifications / Compliances

  • Meets ASTM C 494 Types S


 EUCON AWA is packaged in 275 gal (1041 L) totes, 55 gal (208 L) drums and 5 gal (18.9 L) pails.
