Smart protection of concrete structures thanks to hydrophilic self-healing technology

In the fight against concrete degradation and water penetration, more and more designers, contractors and building owners are opting for innovative solutions that not only protect, but also contribute to a longer life of their structures. Penetron offers a solution with a unique range of products based on hydrophilic, self-healing technology.

The concrete industry is under pressure worldwide due to aging infrastructure, stricter environmental standards and a growing need for sustainable solutions. Especially in countries such as the Netherlands and Belgium, where exposure to water, de-icing salts and chlorides is commonplace, effective protection of concrete is crucial.

Self-repairing

Penetron Benelux, led by Olivier Suerickx, brings this innovative technology to the market with the aim of protecting and strengthening concrete from the inside. "We often talk about waterproofing, but with Penetron Admix we go a step further. The concrete becomes not only waterproof, but also self-repairing. With new micro-cracks or cracks, a reaction automatically occurs with the moisture that enters, forming new bonds. That means the structure can 'heal' itself, without intervention."

Protected from the inside out

Unlike conventional coatings or sealers that are applied to the surface and are subject to abrasion, Penetron's technology works from the inside out. By adding Penetron Admix to the mix during the concrete process, the concrete itself becomes active in blocking water and harmful substances. When water penetrates the concrete, a hydrophilic reaction occurs that forms microscopic insoluble structures, permanently blocking water migration. And when new cracks appear, this reaction is reactivated.

Wide applications in new construction and renovation

Penetron technology is used both in new construction and in repairing existing structures. For renovation projects, there are specific products such as slurries, plugs and injections. These penetrate deep into the concrete and form an internal protection there against further penetration of moisture or chemicals. However, the real breakthrough lies in the application of Penetron Admix in new construction. The concrete is actively protected from day one. This allows savings on additional waterproofing layers or membranes. The choice to save on shrinkage reinforcement also becomes a possibility "The impact on the total cost of ownership cannot be underestimated. It makes the whole construction process simpler, more sustainable and efficient," Suerickx said.

Internationally proven performance

Although Penetron has been used worldwide for decades - from dams in Greece and tunnels in Sweden to subway stations in Dubai - the technology is still relatively new in the Benelux countries. Yet confidence is growing rapidly. Recent tests showed that concrete with Penetron Admix lasts more than sixty years longer than traditional concrete in environments with high chloride concentrations. That life extension makes the product ideally suited for applications in aggressive environments: underground structures, parking garages, tunnels, water treatment plants and coastal areas where concrete is put to extra heavy tests.

Simplicity and sustainability

What sets Penetron apart is its simplicity of use combined with a lasting effect. The technology is active as long as the concrete lives. It requires no maintenance, is environmentally friendly and prevents expensive repairs in the long run. With a clear mission to extend the life of concrete structures while reducing the ecological footprint, Penetron Benelux is ready to further expand its position in the region. "Our technology fits nicely with the future vision of the construction industry," concludes Suerickx. "Sustainable building starts with smart material choices and we believe that hydrophilic, self-healing technology will play a key role in this."
