Batimix IWR 410

Liquid, integral water-repellent for concrete


BATIMIX IWR 410 is a liquid integral water-repellent admixture used in all types of concrete mixes to reduce absorptivity and water penetration from the surrounding environment. It is formulated from carefully selected inorganic stearate raw materials imparting water-repelling properties. Upon request, this product can be supplied in powder form.

Main Purpose

BATIMIX IWR 410 significantly decreases the water-permeability of concrete without altering its fresh and hardened properties. It forms a network of insoluble water-resistant material within the pores of the cement matrix. This yields an effective internal barrier preventing water transmission.

Applications using BATIMIX IWR 410 include all types of plain and reinforced concrete castings such as precast, ready-mixed, lightweight, pumped, and shotcrete.


Concrete prepared with BATIMIX IWR 410 is characterized by the following:

In the plastic state:

  • No detrimental effect on workability or setting

In the hardened state:

  • Minimized water permeability, capillary suction, and moisture transfer
  • No negative influence on drinking water in concrete storage tanks
  • Reduced potential for efflorescence and probability for rebar corrosion
  • Reduced attack of soluble salts and aggressive ions
  • Improved concrete durability and better surface quality
