Cristex -  impermeabilizare beton romana english

     How does Cristex work?
In the presence of moisture, the chemically active compounds within Cristex products create a reaction between the un-hydrated concrete particles and water within the concrete matrix that generates millions of insoluble needle-like crystals which block the pores, capillaries and small cracks. It thus forms a permanent and effective barrier to water penetration without affecting the permeability of water vapors and allowing the substrate to breathe. Once they have penetrated into the concrete matrix the chemical compounds of Cristex remain permanently present. Latent when the concrete is dry, Cristex reactivates in the presence of humidity and moisture restarting the process of crystallization and sealing any new potential cracks or water ingress caused by settlement, shrinkage, static or dynamic stress, blocking water penetration as well as significantly inhibiting the carbonation process and penetration of aggressive contaminants like chloride, sulphate and nitrate ions. Laboratory assessments have revealed that beside waterproofing the Cristex treatment virtually improves concrete performance by increasing the compressive strength and its resistance in aggressive environments.

Why Cristex for waterproofing concrete?

Because Crystex is the modern solution to an age old problem! Modern concrete structures usually benefit from new advanced design techniques and new technologies that enable them to cost effectively provide higher quality concrete while solving specific problems. The use of Cristex technology is the modern solution to the age-old problem of waterproofing concrete results in a cost effective solution to increase the quality, functionality and lifespan of concrete while reducing ongoing maintenance and opportunity costs associated with modern concrete structures.


Cristex can be succesfully used for:

- Drinking water reservoirs

- Basements
- Swiming pools
- Manholes
- Diaphragm walls
- Elevator pits
- Bathrooms
- Aquariums


Cristex is a range of products that:

  • Chemically reacts in depth within the concrete to prevent capillary rise of water and water leakage with or without pressure.
  • The crystallization effect reactivates permanently in the presence of water.
  • Seals cracks up to 0,4 mm.
  • Easy to apply by brush, spray and as dry powder over fresh floor screeds
  • Improves the concrete mechanical resistance, abrasion resistance and freeze-thaw resistance.
  • Can be applied on both positive or negative side.
  • Provides resistance to attach from chemicals, sea water, waste water, carbonates, chlorides, sulphates, and nitrates.
  • Approved for use in potable water applications.
  • Short curing times, application can be performed on fresh concrete.
  • Can be applied by brush, spray and power trowelled as dry powder over fresh concrete floor screeds.
