Penetron Admix, a third generation crystalline admixture, is the most advanced formula to effectively waterproof concrete structures. It eliminates problems associated with first and second generation admixtures such as loss of slump and compressive strength as well as unusually long setting times.
Penetron Admix can be applied to any commonly used concrete mix in today’s construction industry. There are no known incompatibilities with other workability admixtures such as retarders or superplasticizers and there are no limitations in regards to the W/C ratio of the concrete to be treated. With dosage rates as low as 0.8% (by weight of cement), it is not only one of the most cost efficient and economic waterproofing choices, but also an effective formula that has been proven in many international laboratories and on countless projects worldwide.
Penetron Admix is non-toxic and contains no volatile organic compounds (VOC). It is approved for use in projects involving potable water (NSF 61 approval, European Environmental License) and green projects acquiring LEED certification points.
ADVANTAGES OF PENETRON ADMIX
Permanent Concrete Protection
Penetron Admix offers permanent protection and does not require any maintenance. It becomes an integral part of the concrete by forming insoluble crystals in the capillaries, pores and micro cracks. Once these crystal formations are fully developed in the concrete matrix, they will remain there forever, turning the structural element into a water barrier. Unlike surface-applied products (membranes, cementitious coatings), Penetron-treated concrete will retain its waterproofing and protection properties even if the surface is damaged.
Penetron Admix is an active waterproofing product that enables self-healing of concrete. Being a hydrophilic product, Penetron Admix reacts with moisture to form crystals in concrete cracks and voids. Should water enter through newly formed cracks, the resulting chemical reactions form more crystals to seal any new cracks, even decades after construction.
Corrosion protection of reinforcement steel
By sealing the capillaries, pores and micro cracks of concrete with insoluble crystal formations, Penetron Admix reduces the permeability of concrete and denies water and corrosive chemicals an entryway into the structure. Water-borne salts, chlorides and other chemicals cannot reach the reinforcement steel, preventing corrosion or a breakdown of the alkaline in the concrete (lowering of the pH levels) and protecting the rebar coating.
Protection against chloride penetration
Chlorides are a major cause of corrosion in concrete, usually entering over time through the capillary system. Independent tests have shown that the chloride content of Penetron Admix is very low (<0.10% aggregate) and unrelated to its waterproofing effects. Penetron-treated concrete is resistant to acidic and alkaline conditions ranging from pH 3 to pH 11.
