The solution for a more economical alternative is to work from the inside with negative waterproofing development and designed specifically to waterproof mineral substrates as concrete from the inside (negative side) by reacting to the moisture in the wall as well as the components of the substrate to produce crystals that block the pores.

Crystalline penetrates into the substrate and so becoming an integral part of the wall that blocks water transmission while remaining open to vapour diffusion, which will not detach from the substrate.


  • Environmentally sound and certified
  • Suited for all mineral substrates
  • Becomes an integral part of the structure
  • Resistant to sulfates and chlorides
  • Self-healing properties on micro-cracks
  • Resistant to freeze and thaw cycles
