How The Penetron System Works 

The Penetron chemicals penetrate into the the capillary tracts of the concrete by pressure of osmosis, Brownian movement and dry particle reactions.

The active ingredients of Penetron react with various concrete minerals forming insoluble crystals which fill out cracks, pores and voids up to a width of at least 400 microns. This crystalline growth will eventually take place deep inside the concrete structure and has been found as deep as nearly 1 meter from the point of application.  

Water molecules (and a wide range of chemicals) are no longer able to pass through the concrete. However, air can still pass allowing the concrete to breathe and avoiding vapor pressure to build.
In the absence of further moisture, Penetron components lie dormant. Should moisture recur at any time, the sealing process resumes automatically and advances ever deeper into the concrete.
