  • It is an admixture that makes concrete waterproof, corrosion-free and self-healing.
  • It is used to protect concrete structures against water ingress, shrinkage and cracking, chemical attack and corrosion of reinforcing steel.
  • Dosed at 2.5 kg/m³ of concrete subject to concrete mix design.
Krystaline Add Plus 2.5 - Aditivos impermeabilizante para hormigón


Krystaline Add PLUS 2.5 is a hydrophilic C-S-H technology admixture creating waterproof concrete through hydration enhancement. The catalytic nature of Add PLUS 2.5 reduces the pore and capillary structure through the generation of increased and enhanced C-S-H (calcium silicate hydrate) amorphous gels in the pore and capillary network of the concrete to effectively stop water ingress. The resulting concrete has a significantly greater ability to resist water penetration under hydrostatic pressure.


  • Stops water ingress into concrete.
  • Self heals and waterproofs cracks up to 0,4 mm.
  • Protects reinforcing steel against corrosion.
  • Total and permanent waterproofing.
  • Becomes an integral part of concrete.
  • Resists sulphate and chloride attack.
  • Waterproofing improves over time.
  • Excellent resistance to sulfate and chloride attack
  • Waterproofing and durability not affected by surface abrasion
  • Excellent resistance to hydrostatic pressure.
  • Waterproofs under positive and negative pressure.
  • Permeable to water vapor.
  • Suitable for use in contact with potable water.
  • Replaces conventional waterproofing systems.
