Crystalline Materials

BETOCRETE-C series of crystalline materials are available in liquid and powder waterproofing admixtures as well as in dry ready mix powder. 

Self-healing nano crystals

The BETOCRETE-C admixture within the concrete reacts with moisture and free lime in the concrete to create millions of insoluble crystalline fibres that fill the pores, capillary tracts and minor shrinkage cracks within the matrix. This permanently blocks the passage of water through the concrete, either from the positive or negative water pressure side. BETOCRETE-C can be added to the concrete mix at the time of batching or to a concrete mixer with full mixing capabilities at the job site.

For post-applied crystalline waterproofing, the ready mixed AQUAFIN-IC or ASOCRET-IM mortars can be applied to the existing concrete structure.

Typical applications

  • Waterproofing of concrete according to
    • German "waterproof" concrete standard
    • BS 8102 Type B waterproofing
    • Less capillary absorption under non-hydrostatic conditions
  • Extending the lifespan of the concrete structure
  • Self-healing ‘normal’ concrete to make it more waterproof

General advantages

  • Enhances the durability of concrete
  • Self-seals static hairline cracks up to 0.4 mm
  • Does not block vapour
  • Impervious to physical damage and deterioration
