Sistema Penetron®

Penetron chemicals penetrate concrete cracks, microcracks, and capillary channels through osmosis, Brownian motion, and reactions between dry particles. Their active ingredients react with existing minerals in the concrete, forming insoluble crystals that fill pores, voids, and cracks up to 500 micrometers wide. This crystalline growth develops in depth within the structure, potentially advancing up to one meter from the point of application.

Once this crystalline shield is formed, water molecules — as well as a wide range of chemicals — can no longer penetrate the concrete. However, air continues to circulate, allowing the concrete to “breathe” and preventing the buildup of vapor pressure. In the absence of moisture, Penetron components remain inactive; when moisture is present again, the self-healing process automatically reactivates and progresses even deeper into the structure.

With over 50 years of development and presence in more than 100 countries, the Penetron® system is an integral, time-activated technology that uses moisture itself as a vehicle. Economical, versatile, and highly reliable, this solution ensures the durability of concrete structures throughout their service life.
