Donplast Anti-Wash
Antiwash admixture system for underwater concrete (Formerly known as Flocrete Anti-Wash)
  • Higher concrete strength in the underwater concrete applications by significant minimizing the washout of cement particles.
  • Improve workability by reducing placing and compaction problems.
  • Minimizing segregation and bleeding problems by improving cohesion.
  • More durable concrete as a result of reduction in permeability and lower water to cement ratio.

Donplast Anti-Wash is concrete admixture formulated from selected polymers specially designed to produce more cohesive grouting and concrete mixes. It surrounds the cement particles by gel action to minimise the washout in the underwater cementitious applications.

  • Underwater concrete applications.
  • Foundations and piles where high water table occurs.
  • To produce cohesive concrete mixes.
  • Fluid grouting that may have subject to washout.

Donplast Anti-Wash is available in 22 lb (10 kg) bags.


The recommended dosage of Donplast Anti-Wash is 0.25 - 1.0 % of cementitious materials weight in the mix, including GGBFS, PFA or microsilica.

Representative trials should be conducted to determine the optimum dosage of Donplast Anti-Wash to meet the performance requirements by using the materials and conditions in actual use.
