Product Detail




Penetron® products are non-toxic and approved for use in potable water storage and delivery systems worldwide. They are designed to make concrete durable, watertight and significantly increase its resistance to chloride penetration and sulphate attack in aggressive environments.

Penetron® Admix is a chemical concrete additive providing total concrete protection to commercial, industrial, infrastructural and residential developments. Penetron® Admix improves the durability of concrete, thereby substantially lengthening the lifespan of structures. In addition, the Penetron® suite of Total Concrete Protection products is used for concrete waterproofing, protection and repair.

Penetron Admix™ consists of Portland cement, specially treated quartz sand and a compound of active chemicals. It is added to the concrete mix at time of batching. Its active chemicals react with the moisture in fresh concrete and the by-products of cement hydration to cause a catalytic reaction, which generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete, thus waterproofing and protecting while adding significant durability to the life of the structure. It can be incorporated into ready mix concrete and precast concrete for below-grade concrete structures, landscaped external concrete terraces over enclosed spaces, balconies, retaining walls and concrete roof structures. Over the course of a two year testing program, Penetron Admix was tested for durability and was shown to add up to 60 years to the life of certain concrete products it was added to.

Penetron® is a surface-applied, integral crystalline waterproofing material, which waterproofs and protects concrete in-depth.  Penetron® needs only to be mixed with water prior to application. Penetron® integral crystalline waterproofing can be applied to all structurally sound concrete - new or old. It may be applied to either the positive or negative sides of the concrete face. Penetron® has no added solvents, minimising net VOC emissions.

When the product is applied onto a concrete surface or mixed into the concrete, the active chemicals combine with the free lime and moisture present in the capillary tracts of the concrete to form an insoluble, crystalline structure. These crystals fill the pores and minor shrinkage cracks in the concrete to prevent any further water ingress and increase durability. The concrete dries out but remains vapour permeable, preventing the growth of toxic mold in enclosed spaces.  It can also seal cracks of up to 0.4mm rather than masking or bridging them. Even after the concrete has cured, Penetron® remains dormant in the concrete and will reactivate in the presence of moisture to seal capillary tracts and hairline cracks. In addition to waterproofing the structure, Penetron® also protects the concrete against seawater, wastewater, aggressive groundwater and many other aggressive chemical solutions. Penetron® Admix™ and Penetron is approved for use in contact with potable water and is therefore suitable for use in water storage tanks, reservoirs and water treatment plants.
