Anti-washout admixture, for placing concrete underwater, or on porous or wet substrates.


  • Concrete can be exposed to water without excessive washout.
  • Eliminates time and expense of dewatering hydraulic structures prior to placement.
  • Eliminates the need for pumps or tremmies when direct placement is possible.
  • Self-leveling and self-consolidating.
  • Allows direct underwater concrete placement in repair locations.
  • Effective in fresh and salt water environments.
  • Improves concrete workability with no loss in strength.
  • Higher strengths may be achieved more economically using standard mix designs.
  • Improves cohesiveness and reduces concrete segregation and water dilution.
  • Lower permeability.
  • Higher durability.
  • Addition of high-range water reducer is not required.
  • Improved bond strength to steel and existing concrete.
  • No need for admixture dispensers because Hydrocizer is packaged in patented water soluble Fritz-Pak inner bags for convenient use at the plant or job site.


Fritz-Pak Hydrocizer is a dry powdered admixture, packaged in a ready-to-use water soluble bag. Hydrocizer is a polymeric fluid loss additive combined with a premium superplasticizer formulated to physically bind with the water in the concrete and provide maximum water reduction for controlled slump while producing stronger more durable concrete. The special combination yields an admixture suitable for concrete placement in fresh water as well as marine environments.

When used as an anti-washout admixture, Hydrocizer allows placement of concrete in underwater applications without segregation, reduces water requirements, increases concrete compressive strength, reduces permeability and increases durability. Hydrocizer is recommended for all types of underwater concreting where performance with decreased segregation, lower water-cement ratio, and improved slump characteristics are desired. Hydrocizer does not contain calcium chloride or other potentially corrosive materials and is compatible with all standard concrete admixtures.


Hydrocizer is compatible with most air-entraining admixtures as well as other conventional admixtures. When used with other admixtures, each one must be dispensed separately into the mix.
