Batimix Mortar W-800

In-depth waterproofing slurry by crystallization


BATIMIX Mortar W-800 is a surface-applied cementitious-based material, which waterproofs and protects concrete in-depth. It is made from Portland cement, carefully-graded sand, and a combination of selected additives, including water-reducers, surfactants, anti-foams, emulsifiers, water-repellents, and crystallization chemicals.

When applied to carefully prepared substrates, the active chemicals of BATIMIX Mortar W-800 react with the free lime and moisture present in the capillary pores of the concrete to form insoluble crystalline complexes. The so-formed crystals block the capillaries and minor cracks to prevent any further water ingress.

BATIMIX Mortar W-800 allows the passage of water vapor through the concrete. It can thus be applied against active and passive water pressure surfaces.

Main Purpose

BATIMIX Mortar W-800 may be used in conjunction with BATIMIX Mortar W-810 on vertical and horizontal concrete and masonry surfaces in various applications, such as basement retaining walls, channels, bridges, construction joints, swimming pools, water retaining structures, and concrete slabs including roofs and balconies.


BATIMIX Mortar W-800 has the following characteristics:

  • Ready-to-use, ensuring consistent properties of the fresh and hardened product
  • Can be applied to all structurally sound pressure and non-pressure concrete faces – new or old
  • Strong adhesion to the substrate
  • Very-low water absorption
  • Increased water vapor transmission
  • Improved durability with a high quality finished texture
