Extending the life of concrete buildings

08 October 2014

Penetron® is a chemical concrete additive providing total concrete protection to commercial, industrial, infrastructural and residential developments.

Penetron® 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® may be added at the time of batching or applied post-construction to a suitably prepared surface from the negative and positive side. The crystalline action self-heals cracks up to 0.4mm and remains active for the life of the concrete.

Applications include the strengthening and waterproofing of concrete tunnels, harbours, runways, water reservoirs, basements, slabs, roof gardens and was recently used to great effect in South Africa’s first 6-star Green Star SA Office v1 Design rated building: the Vodacom Innovation Centre.

Penetron’s waterproofing effect is achieved by the reaction of the various chemical components contained in the solution when combined within the concrete matrix. The compound penetrates deep into the capillary tracts of the concrete by pressure of osmosis and forms crystals that completely seal the capillaries and shrinkage cracks to drive out moisture. The process works with or against the pressure of water. In the absence of moisture, Penetron components lie dormant. Should moisture recur at any time, the chemical reaction and sealing process repeats itself automatically and advances even more deeply into the concrete. Penetron chemicals will continuously seal and reseal due to their chemical nature. Crystalline growth from capillary waterproofing has been measured as deep as nearly 1 metre from the point of application. Penetron® is 100% compatible with concrete, brick, mortar, and stone.

Penetron® is available in over 80 countries and has been in existence for more than 30 years. The Penetron® suite of products are imported into Africa by Penetron® South Africa (Pty) Ltd and is available on the continent through an extensive distribution network.
