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.
Here are some examples of where Penetron is used:
Lift pits and shafts
Potable water tanks
Sewage treatment tanks
Balconies and Terraces
Traffic bearing structures
Chemical storage bunds
Penetron should not be confused with a coating or membrane solution. It actually becomes an integral part of the concrete, forming a complete body of strength and durability. The system therefore offers the following benefits:
Penetrates deep into the concrete structure.
Seals concrete's capillary tracts and cracks up to 0.4mm.
Permanent - waterproofing and chemical resistance properties remain intact even after surface damage.
Cannot come apart at the seams, tear or puncture.
More effective and less costly than other systems such as membranes, clay panels or coatings.
Easy to apply and therefore highly labor-cost effective.
Can be applied from either the positive or the negative side.
Resists high hydrostatic head pressure.
Increases compressive strength of concrete.
Does not require protection during backfilling or placement of steel.
Resists chemical attack and provides a wide range of protection from freeze-thaw cycles, corrosion of reinforcement steel, aggressive sub-soil waters, sea water, carbonates, chlorides, sulfates and nitrates.
Can be applied to moist or green concrete.
Can be applied as a slurry (brush or spray), dry-shake or admixture.
Approved for potable water use.
No extensive curing times except for extremely hot weather and low humidity.
We are currently developing detailed schematics for the use of the Penetron system in various scenarios providing a comprehensive source of information. In the mean while, the following diagram outlines how the Penetron system can be used to waterproof a building.
