What is self-healing concrete?
Self-healing concrete is a revolutionary technology that can autonomously seal cracks in concrete without human intervention. This concrete with self-healing properties uses advanced crystallizing self-healing concrete technology to prevent structural damage caused by water infiltration and to extend the lifespan of concrete structures.
How does self-healing concrete work?
The technology behind Penetron self-healing concrete is based on a unique crystallization process. When water enters a crack or void in the concrete, special chemical components are activated. These react with free lime in the concrete and form insoluble crystals that fill the cracks and restore the structure’s waterproofing. This makes durable self-healing concrete particularly suitable for infrastructure projects and industrial applications.
Chemical process of self-healing concrete
When water enters a crack, a chemical reaction starts: Ca(OH)₂ + SiO₂ + H₂O → CSH-crystals. These calcium silicate hydrate (CSH) crystals grow and seal the microcracks , preventing further damage from moist and external influences.
Applications of self-healing concrete
Zelfherstellend beton met Penetron-technologie is ideaal voor diverse toepassingen zoals:
Infrastructural projects: Bridges, tunnels, dams and locks
Watertight constructions: Pools, water reservoirs and basements
Industrial applications: Water basins, factory floors and cooling installations
Port and maritime structures: Protection against salty environments
Construction projects: Underground parking garages, foundations and concrete structures with a long lifespan
Why choose Penetron?
Penetron offers a proven, permanent solution for concrete. Thanks to innovative technology, structures remain intact for years and resistant to the most challenging conditions. The system provides automatic crack repair, enhances waterproofing, and extends the lifespan. Additionally, it requires less maintenance, maintains structural integrity, and contributes to an environmentally friendly construction solution.
Self-healing concrete and maintenance
With Penetron self-healing concrete, maintenance costs are drastically reduced. Concrete with automatic repair mechanisms prevents costly manual repairs and extends the lifespan of structures. This makes it ideal for both commercial and industrial applications where durability and corrosion protection are essential.
Self-healing concrete autonomously seals cracks, prevents water infiltration, and reduces the need for manual repairs, significantly lowering maintenance costs.
It is suitable for bridges, tunnels, dams, locks, parking garages, foundations, swimming pools, water reservoirs, industrial applications and maritime infrastructure.
Thanks to the crystallization process, self-healing concrete can last up to 50 years or more without structural degradation.
It maintains its strength better because cracks seal themselves and reinforcement corrosion is prevented , making it more durable than traditional concrete.
